How to Make and Photograph Rainbow Water Droplets on a CD

02 Jul

Do you enjoy doing a nice experiment, that gives you colorful photographs? In this article, you’ll discover how you can create a photo of rainbow water droplets using simple household objects and your imagination. The technique uses the principles of refraction and applies it in an easy to use way.

A nice experiment to do while it’s raining outside, create your own water drops and photograph them in an experimental way. So it’s time to setup your home laboratory, and photograph droplets on a CD!

You can make some captivating rainbow colors by using this technique.

What you need to photograph water droplets on a CD

As mentioned, you’ll need just some simple household items to carry out this photo of rainbow water droplets. You’ll also need some camera equipment as well!

  • CD – This is what’s needed to create the rainbow effect, make sure the shiny surface is clean.
  • Water dropper – Any simple dropper will do, you could use an eye dropper perhaps.
  • A glass of water – You’ll need a supply of water handy.
  • A flashlight – Any flashlight or headlamp will work for this technique.
  • A camera – Your camera must be capable of doing long exposures.
  • A macro lens – This works best with a macro lens or a camera with a built-in lens capable of close-up photography.
  • A tripod – This is a long exposure technique, so you will need a tripod.
  • External shutter release – In a pinch, you could use the camera’s self-timer, but an external shutter release will be better.

These are the items you’ll need for this technique.

The method

The following describes the simple method you’ll need to follow when creating this style of photo. The most important thing is you’ll need a dark room.

  1. Place your CD on a flat surface, this can either be a tabletop or the floor.
  2. Add water droplets to the surface of the CD using the dropper. Make sure they make a nice pattern.
  3. Now put your camera on the tripod.
  4. Position the camera and tripod so that the camera is looking straight down onto the CD.
  5. Focus the camera using manual focus and live view. Keep the camera in manual focus so that you retain the focus position. If your camera is on autofocus, when you turn the light off and hit the shutter, you will lose the focus.
  6. Your camera should be set to expose for around 20-30 seconds, the aperture will need to be around f/10-14. This aperture allows for both the long exposure and keeps the depth of field for the water droplets wide enough to ensure they’re all focused.
  7. Now switch the light off. Ensure the room is as dark as possible, so avoid one where there might be light seeping in from outside.
  8. Hit the shutter or trigger to begin the exposure.
  9. Turn your flashlight on. Make sure the light does not shine up directly into the lens element, use a lens hood if you have one.
  10. Keep the angle of the light roughly vertical and slightly down towards the surface.
  11. Now circle the light source around the CD, and let the magic happen! Adjust the length of time you do this for depending on how bright you wish the photograph to be.
  12. Repeat and adjust as necessary. You may wish to try different angles for the torch (flashlight), the higher the torch the more light you’ll see on the reflective surface of the water drop. Using different camera angles may also work well too.

The basic setup for this photo looks like this. It will of course be dark when you expose the image.

Other water droplet experiments

This is not the only way to photograph droplets, there are in fact a host of different methods out there. Here is a brief list you could also try out.

  • Water droplet – Taken using water dripping into a tub, and captured using a strobe. This is a great technique to try out.
  • Water droplets on glass – Use refraction to make amazing photos with water drops, and repeating patterns.
  • Water droplets after the rain – This one you’ll need to go outside for. Photographing droplets on flowers or spiderwebs always looks nice.

There are lots of other ways you can photograph droplets. This is taken with droplets on glass.

Start creating your water droplet photos!

Photographing droplets is a lot of fun, and I hope you enjoy trying out this idea. Have you ever tried photographing droplets before? Did you use a CD to do it, or one of the other methods mentioned in this article.

As always I’d love to see your images in the comments section, together with any comments you may have.

How to use Photoshop Droplets and Actions to Automate Your Workflow

22 Apr

Most photographers who do any kind of event photography (including corporate or weddings) need to find ways to automate aspects of their photographic workflow. This is because events usually generate a lot of images. There are many ways to automate your workflow. This article will describe a technique for speeding up your workflow using Photoshop Droplets and Actions (rather than Lightroom).

To understand this method you need to grasp a couple of Photoshop concepts: Actions and Droplets.

Droplet Processing

Created using an Action and the Droplet we’ll make below.

Photoshop Actions

What is a Photoshop Action? An Action is a powerful tool in Photoshop which is essentially is a recorded sequence of steps. By recording the repetitive individual steps as a group, the entire sequence can be repeated. Actions are really intended for global edits and not for image specific local edits.

Conceptually, as you develop your editing skills as a photographer, regardless of whether you are using Lightroom or Photoshop, you will eventually develop a style or procedure that you like to do when you process your images. Using Actions will help automate these procedural edits.

Beyond your own types of global edits, Photoshop comes with a small set of pre-configured Actions that are included in the installation of Photoshop.  In addition, there are many Photoshop Actions available either for free or for purchase on the internet.

Many photographers try to engage their followers by selling Actions to achieve particular looks. Anyone purchasing Actions should know that they are just pre-recorded sequences that anyone can do within Photoshop to achieve the same look (they do take time to set up though). Regardless, Actions automate repetitive steps in Photoshop.

Droplets

Droplets are a great way to automate the use of Actions with Photoshop. Droplets are similar to Actions but can be used on many files and activated from outside of Photoshop. There are other ways to do batch processing, but Droplets are a neat and simple way to allow actions to be performed on multiple images.

Sound confusing? Here it is in a nutshell: a Droplet is a small executable file that allows you to drop a folder full of images onto a file on your desktop that will run an action set and create final image results that are stored in another folder.

Why do this?

By using a Droplet, you can take a folder full of images and process them without having to open each one individually. It allows you to perform a long series of repetitive steps on images simply and cleanly. Just drop the folder on the Droplet and walk away to allow your computer to do all the work while you do something more fun, like make a sandwich or watch a Netflix show.

Why not do all of this with batch processing in Lightroom? Lightroom allows for batch processing of images with Presets. But some Actions are too complex for Lightroom and Actions for Photoshop don’t work in Lightroom unless they are specifically built for Lightroom. Any event photographer or any photographer that has to take and process a lot of images needs to find a way to simplify their process to get images finalized.

So how do you set up a Droplet?

First, you need to either decide on an Action or sequence of Actions (you can use more than one) and decide where you want to put the edited files when they are done. To show how to use a Droplet, let’s create a simple action and then set it up as a Droplet.

Step 1: Open an image

Droplet Batch Processing Before - How to use Photoshop Droplets and Actions to Automate Your Workflow

Image before processing

Let’s make a simple action to apply the appearance of motion to an image by applying a radial blur.

The first step is to open an image in Photoshop. You need to start with an image in order to be able to go through all the steps to save the Action and create the Droplet. You can use a pre-existing Action but to create the Droplet you need to modify the Action and that can get complicated.

For this example, you are going to create an Action first, make sure it works, and then use it to create the Droplet.

Launch the image into Photoshop

Step 2: Create the Action

Create an Action - How to use Photoshop Droplets and Actions to Automate Your Workflow

Dialogue box for creating a new Action in Photoshop.

If you already have an Action that you want to run, you can skip the process of recording a new one, but for this example, we are creating a new Action. First, you need to open the Actions panel. If yours is not visible, go to Window > Actions from the top menu.

Once the Actions panel is open, you need to make sure you are not in button mode (button mode has colorful boxes).  If the list in the Actions panel is grey staggered boxes, you are in the right mode. At the top right corner, there is a small wing menu. Open that and choose New Action. You will then see the panel above.

For this Action, we are creating a motion effect using a radial blur. Call the Action dPS Radial Blur (or whatever makes sense to you) and then press the Record button to start recording the Action. You are on your way and you should see a red dot at the bottom of the Actions panel.

Step 3: Create the Radial Blur

Duplicate the image by selecting Duplicate Layer from the pull-down menu at the top of the layer panel (or use the keyboard shortcut Cmd/Ctrl+J).

Duplicate the image - How to use Photoshop Droplets and Actions to Automate Your Workflow

Create a duplicate layer.

The name of the duplicate layer is not important, but this is the layer to which you are going to apply the radial blur. Now, with the new layer selected go to the menu bar select Filter > Blur > Radial Blur. This will open the following dialogue box.

Radial Blur Dialogue - How to use Photoshop Droplets and Actions to Automate Your Workflow

Apply the radial blur.

The default method is spin and the default quality is good. Change these to zoom and best (as seen above). You need to apply a fair bit of blur for this effect, so anything higher than 70% will work. Your dialogue box should look like the image above.

Step 4: Create the Mask

For this effect, you will only be applying it to the outside edges of the image. To do this you are going to use a layer mask. To create the mask, select the layer you just applied the radial blur effect to and then click on the icon with the white rectangle with a dark circle in the center (third from the bottom left). This should create a white square next to the thumbnail of your active layer, that is your mask. The white mask means that your effect is still being applied or showing across the entire image.

Create the Mask - How to use Photoshop Droplets and Actions to Automate Your Workflow

Create a layer mask on the layer with the blur effect you just created.

Once you have created the mask you need to paint on it with black to selectively hide parts of the effect on this layer. Select the Brush Tool and choose a large brush with a soft edge to modify the mask. The size of the brush should be pretty big so that it covers a large portion of the center of your image. Use a really soft brush (hardness of about 15%).

Paint on the mask with black (make sure the mask is selected not the layer itself – square white brackets should be around the mask) over the center of the image to reveal the sharp part you want showing. Use the softness of the brush to make the transition from blur to sharpness gradual. Your mask should now look mostly white with a black dot in the middle.

The finished image - How to use Photoshop Droplets and Actions to Automate Your Workflow

This is the image after the steps have been completed.

Your image should look something like this effect. Your Actions panel has been recording all these steps in the background. Save your image in the format you want (JPG, PSD, TIF, etc.), the location should be your destination folder.

Step 5: Finish recording the Action

Go to your Actions panel and press the square box (stop button) at the bottom of the panel next to the red dot.

Action panel still recording - How to use Photoshop Droplets and Actions to Automate Your Workflow

Finishing the Action, press stop (square) next to the red dot

This stops the action from taking further steps. Your Action is now complete. If you delete the layer with the blur on it, you can test your action on the same image.

Simply go back to the Layer panel, delete the top layer with the mask.  Go to the Actions panel and find the new Action with the label dPS Radial Blur, highlight it, and click the triangle pointing to the right on the bottom line of the panel. This will activate or run the action. If you have done it correctly you will get the same image again. Yeah!

Step 6: Making the Droplet

Okay, we are almost ready to create the Droplet, there are only a couple more steps involved. To make sure the Action works properly you need a fresh instance of Photoshop. So the first thing to do is to close Photoshop and relaunch it.

The steps to make the Droplet from this point on are quite simple. To create the Droplet, go to the menu bar to File > Automate > Create Droplet.

Creating the Droplet - How to use Photoshop Droplets and Actions to Automate Your Workflow

The Droplet dialogue box.

This is the last set of steps but they are important. First, pick a good location for your Droplet. Usually, a great spot is on your desktop. Click the “Choose…” button, select the desktop and a name for your Droplet (give it a meaningful name for you).

Under the Play heading, uncheck all the boxes (these will stop your droplet from processing) and select your new Action from the pull-down list. Set the destination as Folder and choose a destination for your images (it is usually convenient to put the folder on the desktop as well). Uncheck the Override Action “Save As” command.Press OK.   The last thing to do is to create an empty folder (this will be the source folder where you put your images to be processed) in the same location as you put your Droplet (e.g. the desktop). Close and exit Photoshop.

I like having the source folder, Droplet and destination directory close to each other on the desktop. My arrangement looks like this:

Source folder, Droplet and destination folder

A typical layout for a Droplet on my desktop.

Step 7: Using your Droplet

You are now ready to use your Droplet. Simply put your images to be processed (try only a couple to test first) into the source folder (in this case it’s called To Be Processed). The images should be in the same format you chose previously. Make sure Photoshop is not running (sometimes this causes communication errors). From the desktop, highlight the source folder and drag it onto the Droplet.

Here’s what should happen: the Droplet launches, Photoshop starts, runs your action, and saves your images in the destination folder. Using the test image, it should look like this.

The finaished image

The finished test image after processing

Conclusion

Sometimes droplets are finicky to set up but once they work, they work really well. Each image is processed separately one at a time, so you can take a number of images, put them in your source folder and then just drop the folder on the droplet. This allows you to walk away from your computer for a while, grab a coffee, update your Facebook status (#Workinghard!), have a short nap and come back to a finished set of images.

Droplets can really help to simplify your workflow. The only word of caution is that if you are processing a large number of images with an Action that causes the finished image to get significantly larger, make sure you have sufficient hard disk space for the finished images. I have found if you run out of disk space, Photoshop will crash during a droplet operation.

Happy workflow! If you have used Droplets before please share your experience in the comments below, as well as if you have any questions.

How to Photograph Water Droplets on Glass

02 Apr

A little creativity at home can be a lot of fun in photography. In this article, you’ll see how you can make some miniature worlds with some water droplets and a piece of glass!

The process is straightforward enough, you just need some magic sauce. We’ll get to the magic sauce, and why that works in a moment. So let’s take a look at this how-to guide for photographing water droplets.

How to Photograph Water Droplets on Glass

Who can resist photographing the club badge of their favorite sports team?

The equipment you’ll need

With the exception of the camera equipment, all the items you’ll need for this can be found around the home. The following is a guide to that equipment, but you may have other alternatives as well:

  • The glass – You’ll need to find a piece of glass to put the water on. This must be cleaned, so there are no marks. Glass from a picture frame is the obvious source.
  • The stand – A pile of books with a gap in the middle will work here, once again use what you have at hand. You will need to have two piles of books, with the glass bridging the gap. Each pile needs to be around 20cm (8″) high.
  • A background – This is the picture or patterned paper that you wish to appear in the water droplets when you photograph them.
  • A camera – Ideally this will be a DSLR, though any camera that allows for macro photography will work. A camera that allows you to use off-camera flash is better still.
  • The lighting – You have two options here, to use strobes or to use a spotlight. Your result will be better with a strobe that it triggered by a remote attached to the camera hot-shoe. If this is unavailable you could use spotlights to light up the background, the brighter the better.
  • A tripod – A tripod to put your camera on, is the key to ensuring the sharp focus of the water droplets. You can use the camera handheld, but the results will be less sure.
  • The water – A water dropper will be needed to place the water droplets on the glass.
  • The magic sauce -You’ll need some car windscreen water repellent. Using this will make the water form droplets on the glass.
How to Photograph Water Droplets on Glass

Here is some of the equipment needed for photographing water droplets on glass. The most important product to get is Rain X.

The setup

The above equipment now needs to be set up ready to photograph water droplets. This is an easy process, so just follow these steps:

  1. Create two piles of books. These should be around 20cm (8″) in height, and with a large enough gap to fit your background between them.
  2. Clean the glass, ensuring that there are no marks on it.
  3. Place the piece of glass on top of the two piles of books, arranging it so that it bridges the gap between the piles. Be careful with the glass, try to avoid breaking it!
  4. Spray the glass with the rain repellent. Wipe away the excess liquid, and then allow it to dry. This should happen fairly quickly.

    ***The repellent is flammable, so again, please take care handling this liquid.***

  5. Now place some water drops onto the glass using the dropper. The pattern of drops and proximity of each of them to one another is up to you.
  6. Place your background between the two piles of books.
  7. Place your light source over the background. Make sure it’s not going to shine on the glass first, the aim is to bounce the light off the background and back up through the glass.
  8. Position your tripod next to the plate of glass.
  9. Put your camera on the tripod so it is aiming down through the glass. Ensure the tripod is steady and doesn’t tilt or tip over with the weight of the camera body.
How to Photograph Water Droplets on Glass

This is the main setup I used for taking these photos. The strobe is not in the right position yet, it should be aimed at the striped background.

How to take the photograph

With the setup complete, you’re now ready to take the photos. The following is a step-by-step guide on how to do this:

  1. Focus your camera on a section of the glass plate with an interesting water drop formation. To get the sharpest focus turn off the camera’s autofocus and use manual. Now turn on Live View mode, zoom into a droplet (using the magnify view button), and focus the lens manually until the image is sharp.
  2. Move the background around to ensure it’s in the best position. You’ll want to look at both how it looks in the water droplets, and also as a background behind them.
  3. The camera settings you use can be varied, the following are a guide or starting point. The strobe you’re using may vary in strength, but there is certainly no need for full power. A Canon 430ex II at 1/32 power is sufficient. An aperture of f/9 and a shutter speed of 1/60th was used for the photos in this article.
  4. Once you have your photo check your results. You could now focus on some different droplets, move the background, or change the background.

The demonstration photos I took for this article didn’t quite work. In Korea, I was unable to buy Rain X, and the brand I did buy, didn’t work in the same way.

Now it’s your turn!

This, of course, is a form of refraction photography, and not the only way to photograph water droplets.

Have you tried this method, or something similar? How about showing the community your work in the comments section, either past or new images. This is an easy technique to try out at home, and anyone can do it. So why not have a go!?

Here Rain X was used, and the difference is clear. In the background are some colored pencils.

At the time these photos were taken I was living in Malaysia, so this is the Malaysian flag.

This was my first attempt at this style of photo, at this point I wasn’t using Rain X.

How water droplets came to life for a Gatorade ad

13 Jun
Image courtesy UNIT9 and Gatorade

Video production outfit UNIT9 pulled off some neat visual tricks in a recent project for client Gatorade. Using a custom-built ‘rain rig,’ precisely timed water droplets fall to the ground in the shape of a figure. Strobes illuminate the droplets and give the effect of freezing them, and frame-by-frame the water figure appears to run, jump and kick right in front of our eyes.

The figure’s movements were informed by motion-capture, and the rain rig had to be timed to turn water pressure on and off at millisecond intervals. The camera, strobes and rig were all synced to work in concert with each other, and each frame was processed to correct for gravitational acceleration of the drops as they fell.

Manipulating falling water to this extent hadn’t been done before, so the rig was custom built. It’s a neat piece of innovation that plays with the most basic principle of video capture: string together a certain number of still images every second in front of a viewer’s eyes and they’ll look like a moving image. For a behind the scenes look, check out the video below and visit UNIT9’s website.
