Star Stacker lets you create star trail images and timelapses on iPhones, iPads

05 May

Star Stacker, an astrophotography app available for iOS, allows users to create star trail images and timelapses on their phone, computer or tablet. Michael Webb, the developer, posted about his latest creation on Reddit’s r/LandscapeAstro community. To demonstrate a final result from using the app, Webb posted the image, seen above, and explained how he achieved it in the post’s comments section.

Using a Sony a7R III camera and Rokinon 14mm M2 lens, Webb captured 170 15-second exposure images with an ISO of 640 and an F4.0 aperture. Webb then copied the 170 RAW files to his phone using an SD card adapter and stacked the images in the app. To be clear, you can also import JPEG, .tiff or .png images from your iPhone or iPad’s photo app into Star Stacker. Pixelmator was used to combine images of the foreground and stars together for a final product.

After importing your selected photos, you can start creating images or timelapses with the following effects:

  • Full trails – shows every star at full brightness.
  • Faded trails – stars get brighter as the process runs.
  • Shooting star – similar to faded trails but the last image is brighter than the previous, giving off a shooting star effect.
  • Warp modezooms into the image stack slowly creating a warped effect. This will also impact the foreground so post processing may be required if the images have the foreground included.

Astrophotographers typically take a series of images in the same place and stack them to reduce noise. Is 170 necessary? Likely not. This video from Milky Way Mike breaks explains how many photos you should stack and why.

The app isn’t available for Android yet though Webb mentioned he would ‘certainly consider making an Android version depending on how popular this version is.’ One Reddit user pointed out that Star Trails, available on Google Play, could be a decent alternative. Star Stacker is available for $ 1.99 in the App Store for the Mac, iPhone and iPad.

The LomoGraflok 4×5 Instant Back lets you capture Instax Wide images with large format cameras

02 Sep

Lomography is back with the announcement of its latest, well, back. The LomoGraflok 4×5 Instant Back is the world’s first Instant Back for 4×5 cameras designed for Fujifilm Instax Wide film.

Developed in collaboration with large format photography professionals as a substitute for the peel-apart Polaroid film discontinued back in 2016, the LomoGraflok 4×5 Instant Back works with all Graflok-equipped 4×5 cameras and uses a light-tightened film ejection unit to push out the Instax Wide film shots after capture.

Below are a few sample photos, shared by Lomography:

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_2697116613″,”galleryId”:”2697116613″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

The device is constructed of plastic, is powered by four ‘AA’ batteries (LR6) and features an automated frame counter so you know how many shots are left. It measures in at 181mm (7.13”) tall, 120mm (4.72”) wide and 50mm (1.97”) deep, and weighs roughly 500g (1.1lbs).

Below is a guide on how to use the LomoGraflok 4×5 Instant Back:

The LomoGraflok is currently available to pre-order on the Lomography website for $ 134 (MSRP will be $ 149 once launched). The first units are expected to ship in April 2021.

Nikon offer lets you trade up any camera to a Nikon Z5 with a special $100 bonus offer

04 Aug

Nikon has announced an introductory trade-in offer for photographers interested in Nikon’s new entry-level full-frame mirrorless Z5 camera. From now through one month following the Z5’s August 27, 2020 release date, customers will be able to trade-in any working camera from any brand and save $ 100 USD on the Z5, in addition to the trade-in value of their camera. This deal is available retroactively as well, ensuring that those who already preordered through Nikon directly or through an authorized reseller can still get in on this new deal.

The basics of the deal are as follows. You visit Nikon’s dedicated trade-in website to get a quote for your camera. You then purchase a new Z5 (or Z50, Z6 or Z7, albeit without the $ 100 USD bonus). Next, you send Nikon your old camera, with Nikon covering the cost of ground shipping. Once the camera has been received and checked over, Nikon will send you a refund.

As an example, let’s consider the (plausible) case of a Nikon D750 owner wishing to trade-up to a new mirrorless camera, while still being able to use their existing full-frame F-mount lenses via Nikon’s FTZ adapter. Further, let’s assume that the camera is in excellent condition, meaning it shows minimal wear and functions properly. In this case, Nikon will offer $ 495 trade-in value, plus an additional $ 100 with the ongoing promotion. ‘Good’ and ‘poor’ conditions are also available to select, although all three conditions require the camera to function properly. You cannot trade-in a camera that is not functional.

If Nikon determines that the quality of the camera is less than you stated during the trade-in quote process, you will be eligible to return the Z5. However, you will otherwise forfeit the $ 100 bonus if you, for any other reason, return the camera. As expected, there additional terms and conditions to consider, the full list of which can be viewed here.

To participate in the trade-in program, you must have the Z camera shipped to a valid US address. You can trade-in multiple cameras when purchasing multiple Z cameras, but only a single trade-in can be applied per camera, so there is no way to combine $ 100 bonuses on a single Z5 purchase.

Nikon has published a Frequently Asked Questions list for their Z camera trade-in program as well. Before participating in the program, it is highly recommended reading. There is included information worth highlighting.

You can trade in any camera in working condition, not just a digital camera nor only an interchangeable lens camera. Cameras not listed as trade-in options are eligible and Nikon will send a quote within 1-2 business days of receiving your submitted information, in most cases. You cannot trade standalone lenses in as part of the promotion, however, some kit lenses are included in the promotion, such as a Nikon D3000 and accompanying 18-55mm VR kit lens, for example. If you are worried about being without a camera, fret not as Nikon will ship your new Z camera with free two-day shipping and you aren’t required to send in your trade-in camera until your new Z camera has arrived.

If you would like to learn more about the Nikon Z5, which was recently announced on July 21, you can read our detailed overview here. If you’d like a quick hit piece on what you need to know about the Nikon Z5, we have that too. New cameras aren’t released in a vacuum; click here to learn how the Z5 compares to the Sony A7 II and Canon EOS RP.

Let’s Enhance 2.0 introduces new AI-powered algorithms for upscaling your photos

09 May

Upscaling photos isn’t ideal under any circumstances, but when there’s no other solution to making your images higher-resolution, you want to make sure you’re using the right tool. Let’s Enhance, an online-based upscaling tool, has released a 2.0 update that’s effectively built from the ground up with improved algorithms, new enhancement modes and presets for common image types.

Let’s Enhance 2.0 has been restructured with a new UI that puts its entire settings panel in one box for a simplified interface. The updated web app offers upscaling in increments of 2x, 4x, 8x, 16x and a custom setting for more precise scaling. Under its algorithm tab, Let’s Enhance 2.0 offers five dedicated AI-powered algorithms: Auto, Photo, Illustration, Photo 2.0 (beta) and Photo 2.0 Faces (beta). The Photo 2.0 Faces (beta) algorithm uses Let’s Enhance’s proprietary face reconstruction AI to automatically recognize faces in images and prioritize clarity when upscaling.

Also new are six presets, which will automatically apply pre-determined variables to an image based on the specific preset option you choose. The presets include options for photo prints, real estate images e-commerce images and more.

Let’s Enhance 2.0 lets you upscale five images for free (limited to 15MP) before needing to purchase either a subscription or pay as you go credits (where resolution isn’t limited). Below is a price breakdown of the various plans:

To find out more information and to try out Let’s Enhance 2.0 for yourself, head on over to the Let’s Enhance 2.0 website.

Let’s talk about Dorothea Lange

08 Mar
Dorothea Lange at work in California, 1936. Library of Congress, Prints & Photographs Division, Farm Security Administration/Office of War Information Black-and-White Negatives.

If you don’t know Dorothea Lange by name, you know ‘Migrant Mother’. It’s an image that’s practically synonymous with the Dust Bowl, a period of devastating drought in the North American plains that displaced hundreds of thousands. If you’ve opened an American history textbook or watched a Great Depression documentary on PBS, you’ve probably seen Lange’s classic photo.

it’s time to get better acquainted with Dorothea Lange and recognize her for who she was: a complete and utter boss

The work was part of a major project run by the Farm Security Administration, which involved multiple photographers including Walker Evans. Lange played a major role, and is best known for this Depression-era work, while other images like her photos of Japanese American internment and incarceration have only relatively recently gained wider recognition. And it probably comes as no surprise that behind this legacy was an incredibly resilient, hardworking woman whose body of work is as moving and relevant today as it was decades ago.

So just in case you haven’t already, it’s time to get better acquainted with Dorothea Lange and recognize her for who she was: a complete and utter boss.

She knew she was a photographer before she ever picked up a camera

On graduating school and being asked what career she’d like to pursue, Lange’s response was quick: a photographer. She’d never actually held a camera before, but that didn’t stop her. She walked into a well-known portrait photographer’s studio one day and asked for any job he could give her. Thus her career was born – she learned the trade and acquired her first camera.

She didn’t let trivial setbacks – like having all of her money stolen – hold her back

Born on the East Coast, Lange launched her career in San Francisco and many of her best-known works were made in western states. So how did she end up settling on the other side of the country? Funny story!

After graduating school she and a friend embarked on what was meant to be a trip around the world with her best friend. They only got as far as San Francisco when they encountered a minor setback: all of their money was stolen. Did they ask their parents for help? Admit defeat and go back home? Heck no, they just got jobs and decided to live there. Lange went on to establish a successful portrait photography business.

Her less well-known photos of Japanese American internment are as poignant and raw today as they were nearly 80 years ago

Well into her professional career she was hired by the federal government to take photos of Japanese Americans during internment and incarceration. Many websites (this one included) have reported in the past few years that the photos she took were hidden for decades from the public by officials, deeming them too biased against the government’s actions.

That’s not the case. While it’s true that the images were withheld for the duration of World War II, they’ve been available to the public ever since. Either way, the photos and the humanity that Lange captured are as poignant today as ever.

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_2013785745″,”galleryId”:”2013785745″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

Even with mobility limitations, she never slowed down

Throughout her life, Lange walked with a limp – an effect of surviving polio in childhood. Toward the end of her career the lingering effects of the disease took a severe toll on her body, and when she couldn’t work through the physical pain any longer, began photographing subjects close to home. She worked right up until her death in 1965, planning her MoMA retrospective – the first for any female photographer.

Dorothea Lange Exhibition at the Museum of Modern Art, New York City, 1966. Photo by Rolf R. Petersen.

Her approach to documentary photography remains exemplary today – even if she didn’t always get it right

Lange considered her portrait subjects collaborators and is quoted as saying “I never steal a photograph.” While many of today’s working photographers share that philosophy, every now and again the debate re-surfaces around street photography and photography in third-world countries when a photo feels less like a collaboration and more like exploitation.

Nobody’s perfect of course. Lange admits that she did not ask for the name of her ‘Migrant Mother’ portrait subject, Florence Owens Thompson, who was embarrassed by the photo and didn’t want to be publicly identified when it began to gain recognition. Despite it being one of the works that solidified Lange’s legacy, Thompson received no benefit from it – financial or otherwise – until her family asked for help supporting her medical care at the very end of Thompson’s life.

However, Lange’s limited interaction with Thompson has been attributed to the photographer’s exhaustion after a long trip, and certainly appears to be a deviation from her standard approach of getting to know her subjects. As photographers – and human beings, really – that’s a philosophy we can still learn a lot from.

News: The Nikon Yellow Program Lets You Try the Nikon Z 50 for 30 Days

21 Dec

The post News: The Nikon Yellow Program Lets You Try the Nikon Z 50 for 30 Days appeared first on Digital Photography School. It was authored by Jaymes Dempsey.

nikon-yellow-program-z-50-camera

Nikon has started a program called Yellow, which allows potential customers to try the Nikon Z 50.

You can get 30 days of use out of the Z 50. And at the end of the trial period, if you don’t like the camera, you can send it back.

According to Nikon’s website:

We’re so confident that you’ll fall in love with the photos and videos you’ll get with your new mirrorless Z 50 camera, especially when compared to the ones you get with your smartphone, we’ll let you try one at home for 30 days. If you don’t fall in love, send it back to us for a full refund, including shipping.

A neat aspect of the program is that Nikon allows you to choose your kit so that you can trial the Z 50 with a 16-50mm VR lens (for $ 999.95 USD), with the 16-50mm lens and a 50-250mm VR lens (for $ 1199.95 USD), or you can just get the Z 50 (for $ 859.95).

The camera arrives with a charger, a battery, and a memory card, so you’ll have everything you need to start taking photos.

Now, you will have to be careful when trialing the Z 50, because you’re responsible if the camera comes back to Nikon in anything less than like-new condition. Note that Nikon makes you pay upfront, either in full or in installments through PayPal, so you’ll need to be prepared to hand over money in advance.

Really, there’s a lot to like about this program with very little to lose; assuming you take care of your camera equipment, you should have no problem trialing the Z50 without risk.

Of course, the Z50 isn’t a camera for everyone. But it does offer a lot of power in a little, fairly inexpensive camera body: a 20.9-megapixel APS-C sensor, 11 frames-per-second continuous shooting, 4K video, and much more. If you’re a user of full-frame cameras, you’ll probably want to go for one of Nikon’s other mirrorless options (or a Canon, or a Sony, or a Panasonic).

But if you’re a hobbyist looking to upgrade from a smartphone, a compact camera, or a consumer DSLR, then the Z 50 is definitely worth a look!

Will you take advantage of this and try out the Nikon Z50?

Security firm warns Android camera vulnerability lets hackers spy on phone owners

21 Nov

Security analyst firm Checkmarx has detailed the discovery of an Android security issue that enables hackers to access a smartphone’s camera app, existing videos and images, audio from the microphone and location information pulled from EXIF data. Though the issue has been fixed on Google and Samsung phones, it remains in many camera apps from other vendors

The security researchers first analyzed the Google Camera app included on the Pixel smartphones. Upon discovering the security vulnerability, which involves ‘manipulating specific actions and intents,’ they found the same issue could be exploited in the Samsung Camera app included in its various smartphone models.

The vulnerability is extensive, according to the researchers. Hackers can access the camera app, use it to capture videos and photos even if the display is turned off or a call is in progress and access content saved to the phone. In addition to accessing the images, hackers could pull the location information from image metadata and use that to locate the handset’s owner.

The exploit introduces a number of privacy issues for users; attackers could use the video recording functionality to record a phone call, for example, and could retrieve sensitive images from the user’s phone for blackmail purposes.

According to Checkmarx, Google confirmed that the issue isn’t limited to the Pixel phones and that it is working with its Android partners ‘to coordinate disclosure.’ Both Google and Samsung released fixes for the security issue in their respective camera apps before Checkmarx published its report. It’s unclear how many phones from other vendors may still be vulnerable to the exploit, however.

Canon PowerShot G7 X III review: the compact camera that lets you broadcast to the world

20 Nov

Silver Award

81%
Overall score

The Canon PowerShot G7 X III is the third in a series of 1″-type sensor compacts aimed at smartphone camera upgraders and enthusiast photographers looking for a small second camera. Its core photography features – notably its fast 24-100mm equivalent F1.8-2.8 lens – are very similar to the G7 X II that preceded it, but Canon has given the Mark III a new Stacked CMOS sensor and Digic 8 processor that together promise better image quality and performance.

The biggest changes in the G7 X Mark III are to its suite of video features, which now includes the option to live stream video: a useful feature for vloggers. Resolution has been bumped up to 4K, with 30p available out of the box and 24p coming via a future firmware update.

Key Specifications:

  • 20MP 1″-type Stacked CMOS sensor
  • 24-100mm equiv. F1.8-2.8 lens
  • Built-in 3-stop ND filter
  • Touchscreen tilts up 180° and down 90°
  • 8 fps burst shooting with autofocus, 30 fps Raw burst mode
  • 4K/30p and 1080/60p video recording
  • Microphone socket
  • Live YouTube streaming support built-in
  • Vertical video capture
  • 1080/120p slow motion video (with no audio or autofocus)
  • Wi-Fi + Bluetooth wireless connectivity
  • USB 3.1 (with USB-C connector) for data transfer and charging
  • 235 shot battery life per CIPA standard

Aside from the lens, the majority of the features highlighted above are new, so the Mark III isn’t just a small upgrade, even if it’s hard to differentiate cosmetically from its predecessor.

The G7 X Mark III is priced at $ 749 and comes in silver/black and black finishes.


What’s new and how it compares

The G7 X III has a new sensor, new processor and a first for a compact camera: live video streaming.

Luna Display now lets you use an old Mac as a secondary display

18 Oct

Products like Luna Display, Astropad or Duet Display have been offering the ability to turn iPads into secondary displays for the Mac for quite some time. However, with its latest macOS version Catalina Apple has integrated this feature into its own operating system, MacOS, making the third party solutions pretty much redundant.

Duet Display has responded to the challenge by making the feature work with Android tablets in addition to Apple’s iPads. The latest update of Luna Display, version 4.0, now brings the ability to use a second and/or older Mac as a secondary display. Luna Display calls this the Mac-to-Mac mode.

Apple’s in-house solution only works with macOS Catalina and the iPad. It is also limited to newer Mac models. This is where Luna Display adds value. In addition to the iPad you can use an old Mac as a secondary display, and it also works with older Mac computers – the main Mac has to run macOS El Capitan or later – and the secondary Mac which is used as the external display can run the even older macOS Mountain Lion which was launched in 2012. This makes Luna Display a good way of making use of an old and unused Mac that might otherwise be collecting dust hidden away in storage.

Luna Display comes in the shape of a hardware dongle that plugs into the main Mac and is available in USB-C or Mini DisplayPort versions. On the software side of things the Luna Display has to run on both machines. For the system to work both computers have to be connected to the same Wi-Fi network.

Luna Display is available now for $ 69. Early adopters can benefit from a 25 percent launch discount. More information is available on the Luna Display website.
