How Snapchat Filters Work

If you're one of the hundreds of millions of people who uses Snapchat every day, you've probably played with its lenses that transform your face into all sorts of humorous, interesting, and horrifying things (trust me, I face-swapped with a clock once, and I looked like a Dali disaster). Making all that magic happen takes a lot of math and computing power, however, and the process is fascinating.

Beware the Golden Myth of Photography

As someone who has spent a life in mathematics, I see a lot of attempts to ascribe mathematical concepts to real-world ideas in an overly simplistic way. The media misinterpreting a single medical study and reporting that a glass of red wine is equivalent to an hour at the gym does not mean you should forget the treadmill and buy more Malbec. Weathermen in Kansas do not expect the flapping of butterfly wings to cause tornadoes. But in photography, there's one incessantly perpetuated myth that drives me crazy.

Learn About the Process of Tintype Photography

Tintypes continue to fascinate us. Despite the process being over 150 years old, its methodical, almost meditative procedure and striking results have kept it alive. It's also a fairly scientific process that involves a good bit of chemistry. Check out this video to learn more about the technical and practical aspects of the practice of shooting tintypes.

Suren Manvelyan: The Person Behind ‘Your Beautiful Eyes’ Extreme Macro Photography

I have known Suren Manvelyan for more than 10 years. When I first met him, I was a graphic designer who was fascinated by photography and he was a physics teacher at school who was looking for opportunities to grow as a photographer. We used to gather with our small Armenian photographer’s community each Friday to share experiences, discuss photography, and develop our skills. Years passed, a lot of the enthusiasts gave up and only a few stayed faithful to their art. Suren, on his behalf, not only grew to a professional photographer, but also didn’t give up on his other interests.

Liftware Put a Gimbal in a Spoon

A gimbal is an important piece of technology that makes for some smooth video. It's the device that stabilizes the camera so you can get that cinematic look in your shot. It removes the vibration and shake. The gimbal's motors keep the camera level as the camera operator moves it. Drones use them, the DJI Ronin is basically a large gimbal, and the DJI Osmo is the latest handheld gimbal that DJI brought to market.
