AI-powered Same Energy is a visual search engine designed to show you aesthetically similar photos

Canadian developer Jacob Jackson has created a new web tool for using visuals to search for images. The AI-powered tool, Same Energy, allows you to either search using text or using a pasted or uploaded image.

Once you have entered keywords or uploaded an image, Same Energy shows you relevant results. In the case of a keyword, you get images that match the keyword. For example, if you search ‘tiger,’ you see images of tigers. What makes Same Energy distinct is that when you upload an image or click on one of the image results, the tool then shows you visually similar images.

After searching ‘tiger,’ these are the initial results Same Energy delivered. Some results are, understandably, illustrations and drawings. I wanted to see wildlife photos of tigers, so I clicked on one of the images to initiate a new search for visually similar images.

To continue the example of ‘tiger,’ I clicked on a nice wildlife photograph of a tiger from the results and then was shown a mosaic of similar photos of tigers. I clicked on an image of a tiger in the snow and Same Energy displayed additional images of tigers in snow, plus other wild cats in snow, such as an image of a lynx, bobcat and a snow leopard.

You can see the image I selected in the top left corner of this screenshot. Many of the results show fairly similar results to the initial image, including with respect to overall color palette and even the pose of the tiger.

I queried ‘Grand Canyon’ and then clicked through on a lovely image with many purple and orange hues. Same Energy displayed many images with similar colors and some that were simply of the same subject.

After searching ‘grand canyon,’ I selected an image with a heavy emphasis on purple and orange. You can see those revised results here.

When you right-click on a particular image, Same Energy displays its source and creator when the data is available. Per Jackson, Same Energy relies upon the same precedent as Google Images and Bing Images. PetaPixel writes that Same Energy utilizes deep learning to produce its results and currently indexes about 19 million images shared on Reddit, Instagram, and Pinterest. The search tool operates without tags and metadata, relying instead only on images.

When you right-click on an image, Same Energy shows its source.

Of Same Energy, Jackson writes, ‘We believe that image search should be visual, using only a minimum of words. And we believe it should integrate a rich visual understanding, capturing the artistic style and overall mood of an image, not just the objects in it.’

If you want to try Same Energy for yourself, click here. The program is in beta but it works well so far. It could prove very useful for photographers looking for inspiration.

World’s largest camera: 3.1 gigapixels for epic timelapse panos of the universe


We have a winner for sensor Top Trumps: the LSST camera is the world’s largest astronomy camera. It’s more than 350 times the size of a full-frame sensor, for reference.

“Space,” according to Douglas Adams’ Hitchiker’s Guide to the Galaxy. “is big. Really Big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.”

It turns out the same is true of cameras made to map space. You may think your full-frame camera is big but that’s nothing compared to the Legacy Survey of Space and Time (LSST) camera recently completed by the US Department of Energy’s SLAC National Accelerator Laboratory.

You may have seen it referred to as the size of a small car, but if anything that under-sells it. SLAC has essentially taken all the numbers you might recognize from photography, made each of them much, much bigger and then committed to a stitched time-lapse that it hopes will help to understand dark matter and dark energy.

Unlike many astro and space projects, LSST is recognizably a camera: it has a mechanical shutter, lenses and rear-mounting slot-in filters.

We got some more details from Andy Rasmussen, SLAC staff physicist and LSST Camera Integration and Testing Scientist.

The LSST has a 3100 megapixel imaging surface. That surface is an array made up of 189 individual sensors, each of which is a 41 x 40mm 16.4MP CCD. Each of these sensors is larger than consumer-level medium format and when arranged together gives an imaging circle of 634mm (24.9″). That’s a crop factor of 0.068x for those playing along at home.

The individual pixels are 10μm in size, making each one nearly three times the area of the pixels in a 24MP full-frame sensor or seven times the size of those in a 26MP APS-C, 61MP full-frame or 100MP 44 x 33 medium format model.

To utilize this vast sensor, the LSST has a lens with three elements, one of which is recognized by Guinness World Records as “the world’s largest high-performance optical lens ever fabricated.” The front element is 1.57m in diameter (5.1 ft), with the other two a mere 1.2m (3.9 ft) and 72cm (2.4 ft) across. Behind this assembly can be slotted one of six 76cm (2.5 ft) filters that allow the camera to only capture specific wavelengths of light.

This camera is then mounted as part of a telescope with a 10m effective focal length, giving a 3.5 degree diagonal angle of view (around a 634mm equiv lens, in full-frame terms). Rasumussen puts this in context: “the outer diameter of the primary mirror is 8.4 meters. Divide the two, and this is why the system operates at f/1.2.”

That’s f/0.08 equivalent (or around eight stops more light if you can’t remember the multiples of the square root of two for numbers that small).

Each 16MP chip has sixteen readout channels leading to separate amplifiers, each of which is read-out at 500k px/sec, meaning that it takes two seconds. All 3216 channels are read-out simultaneously. The chips will be maintained at a temperature of -100°C (-148°F) to keep dark current down: Rasmussen quotes a figure of < 0.01 electrons / pixel / second.

But the camera won’t just be used to capture phenomenally high-resolution images. Instead it’ll be put to work shooting a timelapse series of stitched panos.

The sensor array under construction in 2020. Each of the sensors in the 3 x 3 array being installed is a 41 x 40mm chip. The final camera uses 189 of these imaging sensors, plus another 8 for positioning the camera, along with 8 wavefront sensors at the corners of the array.

The camera, which will be installed at the Vera C. Rubin Observatory in Chile, will shoot a series of 30 second exposures (or pairs of 15 second exposures, depending on the noise consequences for the different wavelength bands) of around 1000 sections of the Southern sky. Each region will be photographed six times, typically using the same filter for all 1000 regions before switching to the next, over the course of about seven days.

This whole process will then be repeated around 1000 times over a ten-year period to create a timelapse that should allow scientists to better understand the expansion of the universe, as well as allowing the observation of events such as supernova explosions that occur during that time.

The sensors, created by Teledyne e2v, are sensitive to a very broad range of light “starting around 320nm where the atmosphere begins to be transparent,” says Rasmussen: “all the way in the near-infrared where silicon becomes transparent (1050nm),”

The sensors, developed in around 2014, are 100μm thick: a trade-off between enhanced sensitivity to red light and the charge spread that occurs as you use deeper and deeper pixels.

No battery life figures were given, but the cost is reported as being around $168M.

A nature photography tour of Madagascar, Part 1: Andasibe

A nature photography tour of Madagascar, Part 1: Andasibe


Madagascar. A huge, wild, faraway Island. Even mentioning its name provokes an exotic, exciting feeling in my soul. I had wanted to visit Madagascar for many years before finally realizing my plans in 2022. It was one of the most wonderful trips I’ve done in recent years, one that stayed with me for a while. It included many adventures, diverse and exciting locations, new experiences and a heck of a lot of photography. Enough photography to be interesting (in my opinion, at least) even for the general photography crowd, not to mention nature photographers.

Madagascar may not be a beginner’s destination in the sense that it poses some challenges to the traveler. My scouting trip included extremely long drives (one of them two days in total, during which we had to sleep in a guest house surrounded by a very tall metal wall…).

In some locations, sleeping conditions aren’t on par with the expectations of the typical western tourist. The already-poor country was also badly hit by COVID-19, which left some of its better hotels permanently closed. It is currently recuperating and reinstating the tourism infrastructure, domestic flight schedule and higher-tier accommodation possibilities.

While it has more than its fair share of domestic problems, Madagascar is an absolute heaven for wildlife and landscape enthusiasts. In this series of articles, I’d like to tell you the story of my scouting trip to this magical island. I hope it gives you new insights and information about its sheer natural diversity and triggers your interest in visiting. While a Madagascar trip is not always easy or comfortable, it is extremely worth it for the adventurous soul.

Without further ado, let’s move on to my first stop on the trip: Andasibe-Mantadia National Park. Andasibe Park is located about 150 km (3-4 hours) east of Madagascar’s capital of Antananarivo, near the small village of Andasibe. It consists mostly of a vast rain-forest, which is habitat to numerous species, many of them endemic, rare and endangered, among which 11 lemur species, including brown lemurs, Diademed sifaka lemur, wooly lemur and others. There are several chameleon species and numerous bird and insect species. Andasibe is especially known for its population of the largest lemur species, the Indri Indri.

In general, lemurs are quite hard to photograph. They are energetic, move around quickly and often, and are increasingly reluctant to get close to humans since feedings are being phased out (a wonderful thing in any other respect). They live in dense forests, so good viewings and compositions are few and far between. The photographer often has to chase the animal as it moves through the canopy, which can be challenging and exhausting, especially in the wet, muddy, humid environment. I got back to the lodge absolutely dirty with mud and plant material from head to toe every day.

Indri Indri (locally called Babakutu, which may be translated as “father of a little boy”) is a diurnal tree-dwelling lemur. It lives in family groups, feeding mainly on leaves but also seeds, fruits and flowers. Photographically, the Indri Indri is a wonderful subject. The black and white fur (with hints of brown and grey) is starkly contrasted by its beautiful, large green eyes (and by the colors of its forest habitat). It is also very loud and often bursts into song, allowing easier detection and photography of the singing itself.

The only photographic disadvantage is that it chooses to stay high up in the canopy most of the time (other than when going to the toilet), which can harm the shooting angle; remember, as wildlife photographers, we usually prefer an eye-level vantage point. When you see an image of an Indri Indri at eye level, chances are it was shot during human feeding, which should be avoided and discouraged.

The song of Babakutu is made of high-pitched glissandos and can be heard from far away. In my opinion, it’s pure joy to listen to. It’s very much an arboreal equivalent of a whale’s song.

Besides the Indri Indri, there are several other beautiful lemur species in Andasibe.

Brown lemurs are some of the most common lemurs, but they’re fun to photograph. They are also the most likely to climb to eye level, making them easier to capture.

The Diademed sifaka lemur is one of the largest and most colorful lemur species. Classified as critically endangered, population estimates for the species range between 6,000 and 10,000 individuals.

Malagasy chameleons are known for their striking colorations. I shot several species of chameleons on the trip, but the most beautiful one was the male Parson’s chameleon, whose coloration was especially vibrant and eye-pleasing.

It’s interesting to note that the female Parson’s chameleon is comparatively dull in appearance. I guess the male is dressed to impress!

Atomos announces Ninja Phone for connecting camera to iPhone for monitoring and recording



Atomos has announced the Ninja Phone, a monitor and recorder that connects cameras with HDMI out ports to the iPhone 15 Pro and iPhone 15 Pro Max. The unit acts as a ‘co-processor’ to encode a camera’s HDMI signal to 10-bit ProRes or H.265 and send the encoded video to the phone. There is also support for USB-C mic input.

A Ninja Phone iPhone app was also announced to control the unit. Through the app, users can control settings and file transfer between the Ninja Phone and their iPhone. The app will also allow for vertical video capture, live streaming and remote file uploading to cloud services. An encoded ProRes file can also be saved locally to the phone as a .mov file, allowing users to build some redundancy into their workflow by having the source camera and iPhone both save the same file.

There are some limits, however. Source camera output taps out at 1080/60p, meaning you can’t send a 4K signal from a camera to the Ninja Phone.

No plans were shared for bringing the device to Andriod phones or other USB-C iPhones.

Atomos’ announcement today spent considerable time gushing about the iPhone 15 Pro/Max display stats (2,000,000:1 contrast ratio and support for Dolby Vision, HDR10, and HLG). Atomos has said the device leans on Apple’s A17 chip to decode the video feed and display video with no latency, so it’s unclear how dependent the Phone Ninja is on Apple’s tech or if there are technical limits for if/when the Phone Ninja may come to other devices.

The Atomos Ninja Phone is expected to ship in June 2024 at an MSRP of $399. The unit will also require a $59 phone case, which Atomos says is needed to “ensure that the locking cable system can be deployed.”

Now your phone can be a Ninja too!

Melbourne, Australia, April 12, 2024 — Atomos announces Ninja Phone, a whisper quiet, 10-bit video co-processor for smart phones and tablets that lets you record from professional HDMI cameras.

The first release of Ninja Phone, demonstrated at NAB 2024 at the Atomos booth (C4931) is designed for iPhone 15 Pro and iPhone 15 Pro Max and their amazing OLED display. It’s a powerful combination that uses Atomos’ world-beating knowledge of Apple ProRes encoding and Apple’s cutting-edge silicon and screen technology to create the world’s most beautiful, portable, and connected professional monitor-recorder.

Atomos has a proud history of working closely with all leading Japanese camera manufacturers and as you would expect from an Atomos product, the Ninja Phone lets you connect any professional camera with an HDMI output to Apple’s magnificent OLED screen in HDR.

The Ninja Phone encodes the camera’s HDMI signal to ProRes or H.265, both formats at superb 10-bit quality for perfect HDR. The encoded video is sent via Ninja Phone’s USB-C output to the iPhone 15 Pro or Pro Max’s USB-C port. The iPhone’s super-advanced A17 system-on-a-chip decodes the pristine camera sensor image to display on the high-resolution iPhone screen.

The display is a massive improvement over typical built-in screens that come with most cameras, boasting a 2,000,000:1 contrast ratio and supporting Dolby Vision, HDR10, and HLG. It can display 11 stops of dynamic range with a peak brightness of 1600 nits, perfect for HDR and outdoor viewing.

The Ninja Phone iPhone app, downloadable from the App Store, controls and coordinates the operation of both the Ninja Phone and the iPhone, making them feel like a single, responsive device. For social media creators who need to shoot in 9:16 portrait mode, the Ninja Phone app adjusts to horizontal or vertical video modes. The Ninja Phone app will run on iOS and iPadOS, and will be downloadable at the time of shipping.

The camera’s output appears on the iPhone screen with zero latency thanks to Atomos’ super-efficient ProRes pipeline – encoding on the Ninja Phone and decoding via Apple’s state of the art iPhone.

We’ve added professional video and cinematic smarts to the world’s most advanced phone, says Atomos CEO and Co-Founder Jeromy Young. Ninja Phone is for the thousands of content creators who capture, store, and share video from their iPhone 15 Pro but aspire to work with professional cameras, lenses, and microphones. At the same time, the Ninja Phone is a perfect tool for longer-form professionals who want to adopt a cloud workflow without a complex and expensive technology footprint.

The ProRes-encoded video can be stored on the phone as a .mov file and/or simultaneously transcoded by the iPhone to 10-bit H.265 for workflows like camera to cloud, or live streaming via the iPhone’s built-in 5G and Wi-Fi 6E connectivity.

The Ninja Phone accommodates external iPhone accessories by integrating a separate USB-C hub to allow necessary professional add-ons like wireless USB-C microphones, for perfectly synchronizing video and audio. Third-party accessories are supported via the Ninja Phone with more added over time.

Powered by standard NP series batteries, a battery eliminator, or a USB-C 5V/3A input, the Ninja Phone charges the iPhone while in use with any of these power sources, ensuring long phone operation can match professional shoots.

Atomos has developed a unique and rugged locking ecosystem to maintain a secure grip on connected HDMI and USB-C cables. With Atomos locking cables, it is the most robust capture cable system available today, although it is fully compatible with standard, non-locking cables.

The iPhone 15 Pro’s enhanced connectivity opens a door for Ninja Phone users to make full use of Atomos’ Cloud Services (ACS). These include super-efficient Camera to Cloud workflows, remote live production, and cloud editing. With ACS, content creators can publish video to social media within minutes, and filmmakers can send their footage to their postproduction team via the cloud for the fastest possible production workflow.

I’m so proud that Atomos is once again teaming up with Apple to unlock video creativity through ProRes, and this time it’s on Apple’s most advanced device ever, the iPhone 15 Pro. I’m especially pleased that this product has no fan and is whisper quiet. Atomos has always had an amazing relationship with Japanese camera manufacturers too, and now the Ninja Phone connects these incredible cameras directly to an iPhone’s storage, monitor and its extraordinary wireless and cell networking,” added Young.

Thanks to the iPhone 15 Pro, this is the first time Ninja users will have access to an OLED monitor screen, which, at 446 PPI, is by far the highest resolution, most capable HDR monitor that’s ever been available to them,” added Young. It’s the perfect partner for many of the new, smaller format mirrorless cameras coming out of Japan, for example Fujifilm’s X100 and G series, Canon’s R5 Series, Sony Alpha Series, Nikon Z series cameras and Panasonics GH and S series.

Remarkably, the Ninja Phone weighs in at just 95gms, and a sprightly 335gms when coupled to an iPhone 15 Pro.

The Ninja Phone will cost USD/EUR 399, excluding local sales taxes, and is expected to begin shipping in June 2024. Customers will also need to choose the case for iPhone 15 Pro or iPhone 15 Pro Max, not just to protect the phone in normal use, but to ensure that the locking cable system can be deployed. The cases will be available separately at USD/EUR 59 each, also excluding local sales taxes.

In summary, the Ninja Phone is an essential addition to any filmmaker’s toolkit. It combines road-tested Atomos ProRes expertise with an out-of-this-world screen, proven professional monitoring features, and built-in mobile connectivity for collaborative, remote editing.
