Filters are optical attachments that attach to the front of the lens. They can be made of glass or resin and are used to restrict the light coming into the camera. Filters are a great piece of kit to consider carrying with you in your camera bag, particularly when you have been doing photography for a while and are more up to speed with how to use your camera. Described below are several key reasons and benefits to using filters as well as how to use them and the different types of filters available.

Filters, like this kit from NISI, are a great addition to your photography kit, particularly if you do a lot of landscape photography.

1. Add color and contrast

Filters are a great way to improve your landscape photos. One of the most popular types of filters available on the market today is a polarizing filter.

There are a few reasons why it is beneficial to use polarizers.

Polarizing filters reduce reflections such as those found on glass or water. They can also help to restore natural color saturation and improve the contrast in your images. An example where a polarizer can be beneficial is when photographing woodlands, waterfalls or greenery to bring out more color in the vegetation.

using photography filters 01

You can vary the intensity of the polarization effect by rotating the filter until you achieve the desired effect. For the optimum effect, you are best to point your camera at around a 45-degree angle to the sun.

There are two types of polarizers available: a square and a circular version. You can use them as part of a square or round filter system.

You can place a square type of polarizing filter into one of the slots of the filter holder system that is attached to the camera lens via an adaptor ring.

The circular polarizer option either screws onto the front of the lens directly or attaches to the front of the square filter system by a ring. The front dial of the filter is then turned to polarize the light on the scene you photograph.

2. Create movement

5 Benefits of Using Photography Filters when Taking Photos

Another great advantage of using photography filters is to create some motion in your pictures.

Have you ever wanted to create more movement to a static looking scene?

Well, by using a Neutral Density (ND) filter, you can.

The way an ND filter works is by reducing the level of light that passes through the camera lens. If you haven’t used them before, they are quite straightforward to operate. You simply slot the ND filter into a filter holder attached to the camera lens. It then blocks some of the light that enters the camera sensor so that you can still use slower shutter speeds in bright daylight.

They come in a range of different densities varying from one, two, three, or even 10 or 16-stops of exposure. The darker the filter, the more significant the loss of light and the stronger the effect they can generate.

You may be wondering, do you really need one? Well, that depends on what you are photographing.

The 10-stop and 6-stop ND filters are specifically designed for long exposure photography. The 10-stop works very well for extending exposure times and blurring moving subjects in your images. It is great for capturing the motion of foliage, clouds, or water.

In comparison, the 6-stop can be beneficial for low-light conditions at dawn and dusk.

They are both advantageous. You can use them to accentuate cloud movement, create cloud patterns, or make running water appear smooth.

3. More balanced exposure

You can use filters to help capture a scene accurately. The fundamental reason for using a Neutral Density (ND) graduated filter is to reduce the amount of light entering the camera across the shaded gray part of the filter and correctly record the scene.

ND graduated filters are very popular for landscape photography as they help to provide more balanced exposures.

As great as modern cameras are you will often find with high-contrast landscape scenes, your pictures will either have a burnt-out sky or a dark, underexposed foreground. This is where the Neutral Density (ND) graduated filter works its magic.

using photography filters 02

In these high contrast scenes, when there are two different very unevenly lit subject areas, an ND graduated filter can be an appropriate solution.

For example, when shooting bright skies or sunsets, the exposure between the sky and the foreground varies significantly. Hence, an ND filter helps to capture the entire tonal range from the brightest to the darkest parts of an image, thus achieving a balanced exposure.

Start by placing the ND filter in the filter holder and position the dark section of the filter over the bright sky. This reduces the amount of light transferred to the sky part of the image whilst allowing the foreground to expose correctly.

This way, you capture detail in both parts of the image without the sky washing out due to too much light.

5 Benefits of Using Photography Filters when Taking Photos

In terms of the different types of ND grads available, they will either have a hard or soft edge where the gradation line gives a stronger or smoother transition from color to clear, respectively.

Hard ND grads are better suited to scenes with straight horizons, while soft grads are favorable when objects like buildings and trees cross the horizon.

ND graduated filters come in different strengths from 0.3, 0.6, 0.9, and 1.2 gradations. A 0.9 ND filter reduces the exposure by 3 stops of light. ND graduated filters alter the transition from dark to light, with 0.3 being a weaker gradation, and 1.2 being a stronger gradation.

4. Enhance images

Using photography filters can help to enhance your photography and different types of images, especially when using special effects filters.

You can get specific special effect filters that slot into your filter holder, such as infrared or black and white filters. Other filters you can use to develop wonderful in-camera effects include sunset and sunrise filters. These provide warm colors for dawn and sunrise.

using photography filters 03

Mist and fog filters are another popular type of special effect filter. They are used to imitate the effects of mist by carefully positioning the filter in the holder. You can also use these filters to clean up images by the removal of distracting backgrounds to create minimal compositions.

Other various filters can enhance effects in your photos. If you love to capture vivid, saturated shots, investing in color intensifiers is of benefit.

The intensifier filters broaden and enhance specific colors without affecting the other tones in your photograph.

Alternatively, there are sky filters available to enhance the colors in the sky, as well as autumn tint filters designed to accentuate golds, reds, and browns.

5. Change white balance

5 Benefits of Using Photography Filters when Taking Photos

When you are out capturing landscapes, you may want to alter the color temperature of the scene. Using specialist color temperature filters can be great for changing color tones with no added color cast.

Consider using photography filters that help to brighten up or cool down the white balance and give accurate color temperature corrections.

Coral filters are a great way to warm up a scene by adding pinks and reds.

Conclusion

In summary, popular filters, particularly amongst landscape photographers, include polarizers, graduated and neutral density graduated filters, and special effects filters.

Consider using photography filters as a way to add color to your images, manage variations in contrast, and to create more dynamic movement such as with clouds or water.

Filters are also a wonderful accessory to help protect your lenses and balance your exposures where tones are significantly different.

How to Create Beautiful, Artistic Photos Using a Book

11 Feb

The post How to Create Beautiful, Artistic Photos Using a Book appeared first on Digital Photography School. It was authored by Ramakant Sharda.

how-to-create-beautiful-artistic-photos-using-a-book

Photography is an art, and every photographer is an artist who uses his or her imagination to create a beautiful work of art. A real artist can take anything and convert it into breathtaking artwork. In this tutorial, we are going to do the same thing. We’ll create beautiful, artistic photos using a book and an LED light.

how-to-create-beautiful-artistic-photos-using-a-book

What you need to create beautiful, artistic photos using a book:

To create beautiful, artistic photos using a book, you need a camera. Any camera, including your mobile camera, will work. A tripod is a “must” to hold the camera. A shutter release cable is also required. You’ll also need an LED torch. Again, the LED light of your mobile will work perfectly for this shoot. You may also use a torch, a bulb, or any other light source – even flash.

Of course, you also need a book. It should be big and have thick, glossy pages so that it will reflect the light well. I used Guinness World Records; if you have this book, you can do the same.

You need a dark room, so it’s better to do this shoot at nighttime.

Setup:

This shoot doesn’t require a complicated setup. Simply open your book from the center and fold over 10 pages, like in the following picture.

How to Create Beautiful, Artistic Photos Using a Book

To find the center, divide the total number of pages by 2; whatever figure comes up, open to that page number.

Now place the book at the edge of a table. Put a light behind the book at a lower angle so that it won’t show in the photo.

You can put a black glass below the book to show the book’s reflection.

Camera settings:

To create beautiful, artistic photos using a book, set your camera on Aperture Priority mode. Set your ISO to 100 and aperture to f/11 or f/16. With these settings and a mobile LED light, you’ll get a shutter speed of between one and two seconds. Because our subject is still, you won’t have any problems.

Fix your camera on the tripod. Set the frame, focus manually, and leave it. Your aperture is too narrow, so you’ll get a deeper depth of field, and the entire book will be in focus.

Don’t forget to switch your camera to manual focus mode.

Workflow:

Now you need to throw light from the back and take the shot.

Play with different angles of light to get different shots, but remember that the light will always be at a lower angle.

Once you get enough shots, change the camera position. Set it a bit lower or higher to get different results.

How to Create Beautiful, Artistic Photos Using a Book

Method two

We have created pictures using LED light. Now we are going to create some different kinds of shots.

For this, you need a big monitor or TV and some abstract images. This method is quite simple. Display abstract images on your monitor or TV and place the book in front of it. There should be some distance between the book and the abstract images so that the abstract images become blurred in the picture.

You’ll need to widen the aperture, so set it to f/4 or f/5.6.

how-to-create-beautiful-artistic-photos-using-a-book

Method three – multicolor book

This method is a little hard and requires some post-processing work, but it’ll give you wonderful results. You should have a basic knowledge of Photoshop and an idea about layer masks.

It requires the same LED light setup.

You are going to take a series of pictures with different-colored lights and merge them in post-processing. You’ll need to use gels or colored gelatin paper to get colorful light.

Take five shots with different-colored lights like white, orange, red, blue, and green. Make sure that you don’t move your camera in between the shot.

Now you’ll use these photos to create a multicolor picture.

how-to-create-beautiful-artistic-photos-using-a-book

Putting it together in Photoshop

  • Open all five photos in Photoshop and stack them into layers.
  • Now select one layer.
  • Press ‘Alt’ and add a layer mask. This will add a black layer mask and hide everything. Do the same with all five layers.
  • Now take a soft brush and make sure that the foreground color is white. Set both brush opacity and flow to 50%.
  • Paint on the layer masks randomly. Change the brush size randomly. Increase and decrease the brush opacity randomly. You can also use special-effect brushes to get different results.

After some time and practice, you’ll get a photo like this.

how-to-create-beautiful-artistic-photos-using-a-book

So, postpone all the programs for tonight and create these artistic photos using a book to get some masterpieces. Then, share them here. If you have any problems, just comment on this post, and I’ll help you solve them.

YouTuber upscales classic film to 4K/60p resolution using neural networks

05 Feb

Chances are you’ve seen the famous short film ‘Arrival of a Train at La Ciotat (France),’ by the Lumière Brothers at some point in your life. If not, the original 57-second clip, created in 1895, can be viewed above.

YouTube creator Denis Shiryaev used neural networks to upscale and resound the original black and white clip. His efforts resulted in a 4K/60p clip that is quite astounding. The absence of jerkiness and artifacts makes the arrival of the train that much more impactful and shows just how powerful machine learning has become. Watch Shiryaev’s updated version, below:

Easy Skin Smoothing Using the High-Pass Filter in Photoshop

13 Dec

The post Easy Skin Smoothing Using the High-Pass Filter in Photoshop appeared first on Digital Photography School. It was authored by Adam Welch.

Easy-Skin-Smoothing-in-Photoshop

When you think about it, shooting portraits can be extremely tricky. Not because of concerns over lighting or wardrobe or hair or even makeup…although…sheesh. One of the largest issues that portrait photographers can face is how much (or how little) to retouch the, well, let’s call them the “imperfections” of their subject’s skin. The amount of skin smoothing and retouching can vary from subtle smoothing of skin to extreme masking of each and every blemish we all possess to one extent or another.

Easy Skin Smoothing Using the High-Pass Filter in Photoshop

Fortunately for us, there is an easy way to take full control of how much skin smoothing we apply (and where) when we bring our portrait images into Photoshop. No really, this is incredibly simple and relies on just a few basic features of Photoshop that won’t give your photos that gaudy, “in your face” sort of skin smoothing.

Let me show you.

The power of the High-Pass Filter

The engine which will drive our skin smoothing effect is an old stand-by tool found in Photoshop called the “high-pass filter”.

If you’re familiar with processing your images in Photoshop, you’ve likely heard about how powerful the high-pass filter can be for sharpening your photos. There’s a great article here at Digital Photography School which talks about how to use high-pass for easy, effective sharpening.

Image: Sharpening with the high-pass filter

Sharpening with the high-pass filter

However, in our case, we’re going to use the high-pass filter to essentially work in the opposite way of sharpening, which is to “soften” or smooth the skin of our subject. Moreover, we will use the high-pass filter to accomplish this task easily and with a realistic outcome. Meaning, it won’t make your subject appear to be made from wax – unless you want them to for some reason.

At any rate, here’s how to apply easy skin smoothing in Photoshop using the high-pass filter.

Duplicate the layer

This is the image we will use to demonstrate our skin smoothing technique with the high-pass filter. Incidentally, it’s a portrait of my father.

Easy-Skin-Smoothing-Using-the-High-Pass-Filter-in-Photoshop

I wanted to preserve the character of his visage while granting a small amount of skin smoothing to areas of his face.

After you bring your photo into Photoshop, the first thing we will do is duplicate that layer. The easiest way to duplicate the layer is to click on it and use the keyboard shortcut Ctrl+J on Windows or Cmd+J for Mac. I’ve renamed the copy just to keep track.

Easy-Skin-Smoothing-Using-the-High-Pass-Filter-in-Photoshop

Add the High-Pass Filter

Next, we’ll add the high-pass filter to our newly duplicated layer.

Find the high-pass filter located under the ‘Filter’ tab. Select ‘Other’ and then ‘high-pass’.

Easy-Skin-Smoothing-Using-the-High-Pass-Filter-in-Photoshop

It’s here where we must set the radius for the high-pass filter, but don’t get nervous. Generally speaking, the higher the number for the radius, the more intense the smoothing effect will be.

Increase the value until you begin seeing more and more of your image coming through from behind the gray mask of the high-pass.

It’s difficult to give specific numbers here, but a radius of 100 and above is a good starting point.

Easy Skin Smoothing Using the High-Pass Filter in Photoshop

Click ‘OK’

Change the Blend Mode

You might be thinking “ewwwwww”.

Easy-Skin-Smoothing-Using-the-High-Pass-Filter-in-Photoshop

You would be correct to recoil, but don’t worry, it’s all about to get better with the next step.

Make sure the newly-filtered layer is selected and then change the blend mode to ‘Overlay.’ You can also experiment with other blend modes (Softlight also works well).

Easy-Skin-Smoothing-Using-the-High-Pass-Filter-in-Photoshop

Notice how the photo now appears to be massively sharpened? This is due to the high radius we set for the high-pass filter which we will need for the next phase of the process.

Invert your adjustments

The skin-smoothing magic happens here.

We must invert the adjustments of our high-pass layer. We can easily use the invert layer keyboard shortcut Ctrl+I for Windows or Cmd+I for Mac. Alternatively, select the ‘Image’ tab, then ‘Adjustments’ and finally ‘Invert’.

Easy Skin Smoothing Using the High-Pass Filter in Photoshop

After the high-pass layer is inverted we can instantly see the effects of the skin smoothing.

Easy Skin Smoothing Using the High-Pass Filter in Photoshop

This global smoothing effect grants the photo a glowy “pictorialist” feel which might actually work for some photos.

Of course, we’re not finished yet. Now we can freely adjust the opacity of this layer until you have the desired amount of overall smoothing.

Easy Skin Smoothing Using the High-Pass Filter in Photoshop

Add a Mask for complete control

You might be happy with the results of the smoothing as-is, which is fine. However, I highly recommend tailoring your skin smoothing effect using a layer mask to achieve the best, most professional-looking outcome.

Adding a layer mask will allow you to add or remove the skin smoothing from the image selectively. Believe me, even if you’re a first time user of Photoshop, working with simple layer masks such as these is incredibly easy. I’m going to approach this next step as if you’ve never used a layer mask before in your life.

First, with the high-pass layer selected, click on the layer mask icon at the bottom of the Layers panel.

Easy Skin Smoothing Using the High-Pass Filter in Photoshop

This will add a mask to the layer.

Depending on your settings, this mask will manifest as either a white or black square. From here, we’ll select our paintbrush from the toolbar…

Easy Skin Smoothing Using the High-Pass Filter in Photoshop

…and make sure that our brush is set to the opposite color of whatever our mask might be.

So if our mask is black, make sure the brush is set with white over black or vice versa. This will make the brush remove the skin smoothing effect wherever we paint.

To add the smoothing effect back in, simply switch the brush color to the same color as the mask by clicking the swatch at the bottom of the tool panel.

And here we have our finished portrait.

Easy-Skin-Smoothing-Using-the-High-Pass-Filter-in-Photoshop

Details are preserved, and yet, we’ve managed to dial back the clock slightly and even-out some effects of aging, all while keeping the overall impact of the photo intact.

Painting the skin-smoothing effect in or out truly is that easy. Also, remember you can adjust the flow rate and opacity of your paintbrush as you work.

Make it an Action…

I’m all about saving work, saving time, and saving mouse clicks. Turning your skin smoothing effects into a Photoshop action is not only a great way to save time, but you can also save multiple variations of skin-smoothing effects. Then make them available with just a single click (maybe two).

By creating an action for your skin smoothing, you can easily access different variations. You can have one with lots of opacity, another with very subtle opacity, and multiple blend modes, all without having to go through each individual step every time you want to produce the skin-smoothing effect.

So when you’ve practiced the steps a few times, it’s a good idea to record them as an action for future use.

Here’s a quick walk-through of creating the action for the skin-smoothing effect we used here.

Click on the actions icon to open your Actions Panel if it’s not already visible.

Easy Skin Smoothing Using the High-Pass Filter in Photoshop

Click on the New Action icon (next to the folder icon) and then name your new action. I’ve gone with the highly creative title “Skin Smoothing 1.” When your ready, click ‘Record.’

Easy Skin Smoothing Using the High-Pass Filter in Photoshop

Photoshop will now record each step you make in creating the skin smoothing effect, including layer opacity and the layer mask.

Once you’ve finished, click the Stop icon to halt the recording. And, viola, your new action is now nested in the Photoshop Actions panel for quick selection later.

Easy-Skin-Smoothing-Using-the-High-Pass-Filter-in-Photoshop

I like to keep my Actions panel in “Button Mode” for easier viewing

IMPORTANT NOTE: It’s important that you stop your action recording prior to painting onto your adjustment mask. For more in-depth information on creating Photoshop actions check out this article by Melinda Smith.

Wrapping up

Just as with any sort of digital post-processing, the amount of skin smoothing (and how you go about it) varies tremendously from photographer to photographer and from subject to subject.

Some prefer the visceral realism of seeing every pore and line in the skin, and some like to see porcelain-smooth skin with no signs of aging or blemishes – to each their own.

This is why using the high-pass filter method for skin smoothing is so wonderful. It allows us to tailor our skin-smoothing effect not only to fit the expectations of the client but also to our own style of portraiture.

I hope you enjoyed this quick and easy guide to easy skin smoothing in Photoshop using the high-pass filter. There are many other methods for smoothing and retouching portraits, and we’d love to hear your favorite technique. Let us know in the comments below!

MIT project uses camera and AI to ‘record’ hidden objects using the shadows they cast

10 Dec

Researchers with MIT’s Computer Science & Artificial Intelligence Laboratory (CSAIL) have published a study detailing the use of cameras and artificial intelligence to recreate hidden actions based only on the shadows they cast. The method produces fairly low-quality results at this time but may be refined for future computational photography purposes that include helping self-driving cars ‘see’ hidden objects in their environment.

Shadows can reveal the presence of things a person may not be able to directly see; in the most obvious example, someone could, for example, perceive that a person is standing around a nearby corner because of the shadow they cast on the sidewalk. Though humans can perceive the movement of objects using their shadows, we cannot determine their colors and may not be able to determine their shape.

The newly detailed MIT AI can, however, recreate videos that include hints about an object’s color and shape based on the shadows it produces. As demonstrated in the video above, the AI was surprisingly capable of recreating the movement and general shape of hands and forearms in motion out of view of the camera. As well, the algorithm generated a video of hands moving large blocks and a small ball, recreating part of each object’s color.

This is the latest example of researchers combining cameras and artificial intelligence to produce seemingly magical results. This past summer, for example, experts with Facebook Research and the University of Washington unveiled an algorithm that can generate ‘living’ animations from individual still images.

Why Using Smart Previews in Lightroom CC is a Good Idea (and How to Set Them Up)

25 Nov

The post Why Using Smart Previews in Lightroom CC is a Good Idea (and How to Set Them Up) appeared first on Digital Photography School. It was authored by Kevin Landwer-Johan.

smart-previews-in-lightroom-cc

Smart Previews in Lightroom CC will help enhance your workflow. They are a smaller file you can work with rather than working on full-sized RAW files.

One of the biggest advantages of using Smart Previews in Lightroom CC is when you work remotely. You can store your RAW files on your main hard drive and keep the smart previews on your portable drive. So if you have your RAW files imported to your main computer hard disk, you can make smart previews for your laptop or external drive. You can even store them on a flash memory device like a thumb drive, SD card, or the cloud.

Smart Previews Lightroom CC

How to use Smart Previews in Lightroom CC

Creating Smart Previews in Lightroom CC is easy and can be done when you import your files or at a later time. Lightroom makes a smaller DNG file (an Adobe Digital Negative RAW image file.) These are compressed and take up a fraction of the space RAW files do. The DNG files are located in a separate folder than the RAW files of the same images.

To configure Lightroom CC to create Smart Previews when you import photos, go to the File Handling panel. This is on the right of your screen after you have clicked on the Import button. Make sure that the Build Smart Previews box is checked.

Smart Previews Lightroom CC

You can create Smart Previews in Lightroom CC when you’ve already imported your photos.

Select the files you want to make Smart Previews of in the Grid mode. Go to Library in the top menu and choose Previews->Build Smart Previews. When an image has a Smart Preview, there is an icon indicating this in the Histogram window.

Why Using Smart Previews in Lightroom CC is a Good Idea (and How to Set Them Up)

Working on a smart preview in the Lightroom Develop Module, you will be working on the compressed DNG file. This means your computer will run faster. To ensure you have this enabled, go to Edit->Preferences. Check the box ‘Use Smart Previews instead of Originals for image editing.’

Why Using Smart Previews in Lightroom CC is a Good Idea (and How to Set Them Up)

What are the main advantages of Smart Previews

The three main advantages of using Smart Previews in Lightroom CC are:

  1. Speed up your workflow
  2. Save hard drive space
  3. Easier remote editing

Once you have created the Smart Previews, your computer manages the image files using fewer hardware resources. The file sizes are smaller, so they draw less of the computer’s CPU, GPU and RAM.

Working with Lightroom CC on a laptop or with an external drive is better with Smart Previews. You do not need to have all your RAW files on a remote hard drive to be able to keep editing. Your edits will be auto-synced (keep reading to learn how to do this).

Remote editing from a laptop or classroom computer is much easier. This is because catalogs with smart previews are so much smaller. By only exporting the DNG files with your catalogs, you are saving a huge amount of space.

Smart Previews Lightroom CC

How to export and re-sync using Smart Previews in Lightroom CC

Once you have imported your photos and created Smart Previews in a Lightroom CC catalog, you can export the catalog or part of it. Simply go to File->Export as catalog and make sure to check these boxes:

  • Export selected photos only
  • Build/Include Smart Previews
  • Include Available Previews

You don’t have to check the ‘Include Available Previews’. But if you have already made adjustments to some images, it’s a good idea to.

Uncheck the ‘Export Negative Files’ box.

Save the file where you can locate it again easily. Now you can copy it to another storage device or the cloud.

When opening Lightroom on your laptop or another computer, select the catalog from your storage device. You can work from your device or copy the catalog to the drive of the computer you are working on.

If you open the catalog from where it’s stored, all the changes you make in Lightroom will be saved there. Copying the catalog file to the hard drive of the computer you are now working on requires you to export it again when you’re finished.

To bring the files you have worked on back to your main computer, simply connect the portable storage. Copy the Lightroom catalog with the images you’ve been working on back onto your main computer’s hard drive.

To do this, go to File->Import from Another Catalog. Now locate the catalog from your portable storage. From the drop-down box, select ‘Replace: metadata and develop settings only.’ Click OK. Your Smart Previews will appear in your catalog, including the changes you made.

Conclusion

Using Smart Previews in Lightroom CC is a game-changer if you often work on your photos from more than one computer. Being able to make use of your laptop because the file sizes are smaller and more portable is a great advantage. It may seem like a little more work to set up to use Smart Previews, but once you have done it a few times, it will seamlessly become part of your post-processing workflow.

Portrait Editing with Luminar 4 – Using Artificial Intelligence

02 Nov

The post Portrait Editing with Luminar 4 – Using Artificial Intelligence appeared first on Digital Photography School. It was authored by Caz Nowaczyk.

In this video by Jacques Gaines, he looks at Portrait editing in Luminar 4 using the artificial intelligence features.

?

Luminar 4 is a stand-alone software or works as a plugin in Adobe Photoshop (which is great if you like working in Photoshop and don’t want to completely swap to new software).

This video uses the plugin version with Photoshop.

Jacques uses a retouched, flattened image in Photoshop and then opens the Luminar 4 plugin and does further editing work on his portrait.

He discusses the different portrait enhancement options that Luminar 4 offers.

Within Luminar, there is a section called “Portrait.”

This is the section that consists of:

  • AI Skin Enhancer
  • Portrait Enhancer
  • High Key
  • Orton Effect

AI Skin Enhancer

Smoothes out the skin on a portrait and does it realistically. You can decide how much you want to apply it from 0-100%.
If you don’t want it to apply to certain sections, you can also mask it out using a brush tool.

Portrait Enhancer

The Portrait Enhance panel consists of:

  • Face Light
  • Red Eye Removal
  • Eye Whitening
  • Eye Enhancer
  • Dark Circles Remover
  • Slim Face
  • Enlarge Eyes
  • Eyebrow Improve
  • Lips Saturation
  • Lips Redness
  • Lips Darkening
  • Teeth Whitening

Jared shows the effects these settings have on a portrait.

When you apply the changes in Luminar, it makes the image as a new Photoshop layer. You can then use a mask to paint out any areas in the image that you don’t want the effects applied to.

Set Up Your Own Cloud System and Avoid Using Commercial Services

30 Oct

The post Set Up Your Own Cloud System and Avoid Using Commercial Services appeared first on Digital Photography School. It was authored by Herb Paynter.

If you’re anything like me, you have taken way more photos than you can access at any given time, especially if you’re away from your home system. In this article, I’ll show you why you should set up your own cloud system so you can access your image files all the time, and avoid monthly fees with commercial providers.

Image storage

set-up-your-own-cloud-system

For most of us, home is where we maintain massive drives full of images, both edited and unedited. Most of which are only loosely cataloged or organized too. When I need to find a particular photo, I perform a pretty detailed metadata-based search spread over my multi-drive setup.

The operation is neither efficient nor pretty.

Particularly when the photo I’m looking for was taken years ago and could be anywhere on my system. It’s far from the tidy professional setup I would like it to be. I’ve been adding to this collection daily since the mid-1980s.

Now multiply this dilemma by being away from home much of my life, armed only with a laptop and maybe a thumb drive or small USB pocket drive. If I haven’t uploaded all my images to one of several cloud storage systems I use, this exercise is over before it starts.

Even if I can access my desktop system, the chances are slim that all those pesky permissions doorstops will let me search all my drives remotely.

Hard-drive mania. Repaving the parking lot

Recently, I counted more than a dozen hard drive carcasses stacked on shelves in my home office.

They have served as photo and file storage depots over the years. Some contain images taken twenty years ago that I didn’t transfer to my newest, latest, largest storage device.

There are some great images that I simply haven’t had the time to weed through and sort out. It’s all pretty discouraging.

For those files I have stored online, many times I have to “qualify” them with a password often deemed incorrect (aargh!). Perhaps I’m simply getting older, but there are too many passwords for too many storage sources for this to be fun anymore.

Frustration and anxiety sets in every time I leave the house with my laptop in hand. I know I’ll need to get to something that I won’t be able to access.

Two months ago, I faced the recurring problem of needing more file storage space. What to do? Yet another even larger hard drive? More online parking space? Where does this cycle end?

Flying the friendly skies

This time I took the time to seriously investigate the commercial cloud systems available.

If you think you’re not using cloud storage, think again.

If you have an Adobe account, you are a member of the Creative Cloud. If you are a Mac user, you have an iCloud account. If you are on Google, you probably are a member of Google cloud. Most likely, you use Dropbox – yet another cloud system.

All these systems provide file access from remote locations, but you certainly don’t have all your files on a single cloud.

While these clouds are wonderful, to some extent, there’s a significant downside to each. There’s also a lot of common problems with each. The restrictions, privacy, cost, access, limitations, and vulnerability involved with each is significant when all the facts are in.

Enter the personal cloud system

set-up-your-own-cloud-system

What I have discovered is the surprise upside of installing my own personal NAS (network-attached storage) system, which is basically a full access file server.

A NAS is a standalone Linux or Windows processor (computer operating system) acting as a full-service librarian attached to host one or more hefty hard drives and providing a significant variety of server services. Each server is available only those to whom the server’s owner (typically known as Admin) gives permission, and accessible from virtually everywhere around the globe.

You can configure each personal multi-drive cloud server as either a single massive drive system or as one of several RAID configurations. RAID stands for Redundant Array of Inexpensive Drives and consists of two identical hard drives recording mirrored copies of your files. Each drive stores identical backups for near-bulletproof security.

These NAS RAID arrays provide from two to twelve terabytes of online storage and backup.

Cloudy skies and bumpy rides

Set Up Your Own Cloud System and Avoid Using Commercial Services

But you should take great care to investigate ALL customer reviews of the various private cloud systems available.

Read beyond the marketing talking points and glitzy advertising and read the comments of current users.

The technology is proven, but not all products are quite as user-friendly as they seem. Lower-priced units sometimes indicate entry-level and basic features. Also, sometimes, the lower price indicates a lesser-quality product.

You can’t judge either books or NAS systems by their appearance OR brand popularity.

The system I originally purchased was manufactured by a highly-rated and respected hard drive company. It consisted of two four-terabyte drives set up as a RAID type 1 system that provided immediate access to virtually all my photos, videos, music, and files.

The server worked wonderfully, as long as I was on my home WiFi network. However, when I attempted to set up access away from home, some air escaped from the balloon. This lack of remote access led to me renaming my server “Fogbank” in protest.

After re-reading, reinstalling, and re-configuring the system as best as I could understand the ambiguous installation instructions, I first contacted customer support via email. Detailed explanations of my failed attempts were responded to by references to endless generic PDF documents in their “knowledge base” and forum discussions.

Unfortunately, my phone calls were handled by friendly technicians whose English was so challenged that I simply could not get a direct answer to my questions.

Multiple attempts to put this Humpty-Dumpty server back together failed over and over. Further reading on the company’s forums revealed hundreds of other frustrated users who had given up on the hardware. I will not name the product or the manufacturer. Instead, I’ll just encourage you to do your diligence and read the reviews of actual users before you buy.

Clear skies ahead

Set Up Your Own Cloud System and Avoid Using Commercial Services

I believe totally in both the concept and the technology of NAS personal cloud servers and have since purchased a quality, value-based product. I’ve spent a bit more than I did for my initial system, but I am rewarded with the amazing freedom and power behind this amazing technology.

I now enjoy speedy access to all files in my vast image library. My personal cloud server system provides file sharing and syncing, and personal multimedia services for streaming video and TV shows. It has a bulletproof backup, home security system monitoring, and many more amazing features.

I can even upload images directly from a photo session (through the camera’s WiFi) to my personal server – no waiting to get home!

set-up-your-own-cloud-system

And best of all, this secure server system is fee-free. Once you own the equipment, your only cost is Internet access. If you have an Internet account, you’re good to go. Monthly fees and service restrictions are only distant memories.

You no longer have to rent the rare air on someone else’s cloud. You can collaborate with other users and photo club members, share and download huge files via FTP, all while being entertained. And they actually call this work!

Check into these devices, ask a lot of questions, and open up a whole new communications experience for as little as a $ 500 investment.
