How to turn a chocolate easter egg into a pinhole camera

In this delightful project, Will Gudgeon turned a frozen chocolate easter egg into a fun and effective pinhole camera. The first step is to eat the contents. "The main challenges were it melting, cracking and light leaks around the seal," Gudgeon writes.

Absolutely spectacular first-ever air-to-air images of supersonic jets' shockwaves interacting

For a decade, NASA scientists have worked on an air-to-air photographic technology that will be used to collect data for the agency's next-generation supersonic airplane project. They've just released these absolutely astonishing "first air-to-air images of supersonic shockwave interaction in flight."

“We never dreamt that it would be this clear, this beautiful," says NASA scientist J.T. Heineck.

From NASA:

The images feature a pair of T-38s from the U.S. Air Force Test Pilot School at Edwards Air Force Base, flying in formation at supersonic speeds. The T-38s are flying approximately 30 feet away from each other, with the trailing aircraft flying about 10 feet lower than the leading T-38. With exceptional clarity, the flow of the shock waves from both aircraft is seen, and for the first time, the interaction of the shocks can be seen in flight.

“We’re looking at a supersonic flow, which is why we’re getting these shockwaves,” said Neal Smith, a research engineer with AerospaceComputing Inc. at NASA Ames’ fluid mechanics laboratory.

“What’s interesting is, if you look at the rear T-38, you see these shocks kind of interact in a curve,” he said. “This is because the trailing T-38 is flying in the wake of the leading aircraft, so the shocks are going to be shaped differently. This data is really going to help us advance our understanding of how these shocks interact...”

While NASA has previously used the schlieren photography technique to study shockwaves, the AirBOS 4 flights featured an upgraded version of the previous airborne schlieren systems, allowing researchers to capture three times the amount of data in the same amount of time.

How to make your own camera lens from sand and rocks

Andy George made his own camera lens with borax, river sand, and soda ash. From PetaPixel:

“It has been one of the most challenging projects I’ve ever done,” George says after completing his lens. “Every single step in the project has been a huge pain.”

Making clear glass took over a dozen tries, annealing the glass pucks took at least four attempts, and grinding the lenses themselves took at least 30 hours of continuous grinding.

Sure, the lens is cloudy and, er, imperfect, but HE MADE HIS OWN DAMN CAMERA LENS FROM SCRATCH!

Astronaut's magnificent photo of SpaceX Crew Dragon capsule approaching the International Space Station

NASA astronaut Anne McClain captured this astonishing image of the SpaceX Crew Dragon capsule approaching her temporary residence, the International Space Station. "The dawn of a new era in human spaceflight," McClain tweeted with the photo.

The SpaceX Crew Dragon, containing supplies rather than humans for this test, docked at the ISS yesterday morning and the hatch was opened a few hours ago. From NASA:

(The mission, called) Demo-1 is the first flight test of a space system designed for humans built and operated by a commercial company through a public-private partnership. The mission also marks a significant step toward returning to the nation the capability to launch astronauts on a U.S.-built spacecraft from U.S. soil.

“It’s an exciting evening,” NASA Administrator Jim Bridenstine said after the launch. “What today really represents is a new era in spaceflight. We’re looking forward to being one of many customers in a robust commercial marketplace in low-Earth orbit.”

This is a real African black panther and it's incredibly rare

View this post on Instagram

A post shared by Will Burrard-Lucas | Wildlife (@willbl) on Feb 13, 2019 at 3:05am PST

In central Kenya, biologists and wildlife photographer Will Burrard-Lucas captured footage of a fantastically rare melanistic leopard, sometimes known as an African "black panther." There are only two known prior photos of an African black leopard, from 1909 and 2007. From National Geographic:

"Almost everyone has a story about seeing one, it's such a mythical thing," says Pilfold, of San Diego Zoo Global's Institute for Conservation Research.

"Even when you talk to the older guys that were guides in Kenya many years ago, back when hunting was legal [in the 1950s and ‘60s], there was a known thing that you didn't hunt black leopards. If you saw them, you didn't take it..."

Pilfold adds it’s curious that the fictional country of Wakanda, home of the superhero Black Panther, is located in East Africa, fairly close to Kenya.

"It's a unique coincidence," says Pilfold. "The only place where we have black leopards is where this place in the Marvel Universe appears to exist."

Photographing computers to show the art inside the black box

[Editor's note: I was utterly taken with the gorgeous photos in the new edition of Core Memory, photographer Mark Richards and writer John Alderman's lavish survey of the vintage computing hardware in Silicon Valley's gem, the Computer History Museum; below is senior curator Dag Spicer's introduction to the book, along with some photos, which the publisher was kind enough to supply -Cory]

What computers mean to us depends largely on what we bring to them. Our expectations, our past experience, the dreams and myths that surround them, their physical characteristics—all these aspects resonate on multiple, often overlapping levels. Read the rest

Striking photo essay about Oakland's Black Panther Party (1968)

Fifty years ago, San Francisco's DeYoung Museum exhibited Ruth-Marion Baruch and Pirkle Jones's striking photo essay depicting Oakland's Black Panther Party at the peak of their community activism and political activity. Starting this week, those powerful images will be displayed again as part of the Vanguard Revisited: Poetic Politics & Black Futures exhibition at the San Francisco Art Institute.

The work is still pertinent today and will serve as a platform to discuss issues of documentary photography, social activism, and how the Black Liberation Movement of the 1960s in many ways manifests itself in the social context of today...

Black Futures is not delivered with a passive voice, but a voice steeped in deft poetics and sharp politics that continue to accumulate power from its own rich history.

See more of the images at Juxtapoz.

To learn about the Black Panthers's inspiring, polarizing, and ultimately tragic history, I recommend the fantastic documentary "The Black Panthers: Vanguard of the Revolution."

Samsung faked a smartphone portrait with a stock photo taken with a DSLR

Samsung's latest phones have a "portrait" mode that cleverly fakes the look of a shot taken with a fancy lens on a full-frame sensor. But a picture they used as an example in an ad turns out to be a stock photo taken with a high-end DLSR. Moreover, the photographer, Dunja Djudjic, has a blog and is currently murdering Samsung.

My first reaction was to burst out into laughter. Just look at the Photoshop job they did on my face and hair! I’ve always liked my natural hair color (even though it’s turning gray black and white), but I guess the creator of this franken-image prefers reddish tones. Except in the eyes though, where they removed all of the blood vessels.

Whoever created this image, they also cut me out of the original background and pasted me onto a random photo of a park. I mean, the original photo was taken at f/2.0 if I remember well, and they needed the “before” and “after” – a photo with a sharp background, and another one where the almighty “portrait mode” blurred it out. So Samsung’s Photoshop master resolved it by using a different background.

Huawei did exactly the same thing a while back. We wonder at the sheer stupidity of it, but I wonder if that's just confirmation bias, in that the stupid ones get caught.

Just think of all the plagiarism that's going to be exposed virtually overnight when someone turns the AIs loose on the problem. But also the false charges of such, generated by the normal and natural lines of influence and fair use it will also reveal. Read the rest

The Death of Tumblr

Tumblr will ban 'female-presenting nipples' and other content beginning December 17, 2018. Photographer and writer Nate 'Igor' Smith is a longtime Tumblr user whose work straddles the boundaries of art, editorial, and adult. Here, Nate explains why Tumblr's decision to censor is devastating for the Tumblr's longtime users, and the rest of us. — XJ

THERE WAS A TIME when Tumblr was my favorite place to post photos. It was a social network that you could customize in so many ways that you could create a blog or a mood board or hide a secret project behind a password protected gate. It was used by so many people in so many different ways. You could posts .gifs on Tumblr before they worked on Twitter and you could post uncompressed images that looked good on desktop or smartphone without having to know any code.

I used it as a great place to post images that I could then send to Twitter to get around Twitter’s terrible compression and constantly flowing feed. I used it as a place to organize my images because of Tumblr’s tagging system. I could search for a person or subject or send someone a link to just a specific tag so they could see all my favorite photos of juggalos for example. It was a fantastic tool and my most popular social network until Instagram really exploded. Read the rest

Behold! A 400,000 megapixel panorama of Prague!

Jeffrey Martin (previously) writes, "I shot this gigapixel image last year in mid November. It's made of 8000 photos, shot with a fullframe SLR and a 600mm lens. It was shot from the top of Prague's 'Orloj', the clock tower on Old Town Square, built in 1410. The tower had a scaffolding all over it at the time, going all the way up past the top of the roof: a perfect platform for a high resolution 360º photo, if only I could get up there! I actually didn't even consider trying, as the answer to such questions is usually 'no'. My colleague, a rather more enterprising Marketing guy, was able to smooth talk them into saying 'yes'. Wow!
