The Role of the Slit-Scan Image in Science and Art

The use of slit-scan photography is actually quite old. It is often called line-scan, photo finish, or streak photography. Slit-scan photography has a rich and colorful history rooted in chemical analog photography. This technique is often used to visualize high-speed events such as missiles and bullets, although it is probably best known as photo finish photography used to determine the outcome of races.

The Expanding Universe of Crowdfunded Photo Gear

I confess: I’m a photo gear junkie. I’ve bought dozens of cameras and lenses, way too many tripods, camera bags and backpacks, and many thousands of dollars’ worth of filters, flash units, and other accessories. I’ve tempered my obsession over the last few years, mostly because there's only so much room to store these things, but from the flood of new products hitting the market recently I'd say I slowed down just in time.

Photos and Color Profiles: The Quickly Approaching Move to Wide-Gamut

My name is Kelly Thompson, and I'm a VP at 500px.

Photo Studio Polyboards and Thrifty Alternatives

Nearly every professional studio I’ve ever used has these "polyboards" and you‘ve probably even seen them yourself but may not have known what they’re used for.

One of the other defining characteristics is that they are often white on one side and black on the other.

My name is Robin Roots and I'm a photojournalist for Õhtuleht, one of the largest newspapers in the small country of Estonia. Our team of five photographers has to write down every trip we do with a company car. I was looking over our trips from last month and thought that perhaps others would like to know what we newspaper photojournalists do on a daily basis.

Gerda Taro: The Woman Who Invented Robert Capa

Gerta Pohorylle was born in 1910 in the German state of Stuttgart to a middle-class Jewish Galician family.

In spite of her bourgeois origins, she became part of socialist and labor movements while still very young.

A Forgotten Solution to the Problems of Zoom Lenses

For a few years now, I’ve had in my collection one very strange lens. I bought it primarily for its value as a collectible so, up until now, I haven’t really spent much time playing with it. Made in 1975, this manual focus Minolta MC Rokkor-X 40-80mm f/2.8 lens is one strange puppy.
