Lens Hoods Can Ruin Photos Taken in Cold Weather

Photographer Steve Perry was out photographing snowy owls with his wife when they both realized that something seemed off about their photos: they were soft. After some testing, he realized that the culprit might be his lens hood.

Lenses Don’t Cause Perspective Distortion and ‘Lens Compression’

The focal length of lenses doesn't cause perspective distortion, which is often explained as "lens compression." Period. Now before you call me crazy and dismiss whatever I have to say, I’d like to invite you to take a dive into how lenses work and what actually causes perspective distortion.

Venus Optics Releases 4mm f/2.8 Fisheye Lens with 210° Field of View

This is Why ‘Zooming with Your Feet’ Isn’t the Same Thing

"Zooming with your feet" means getting closer to your subject physically instead of relying on a longer lens, but you should be aware that the results you won't be the same.

This is How Cameras Glitch with Photos of Propellers

If you've ever photographed spinning airplane propeller or helicopter rotor blades with your smartphone, you may have found that the spinning blades were turned into bizarre shapes in the resulting photo. What you're seeing is distortion caused by a rolling shutter, when a CMOS sensor captures a scene by scanning across it very quickly rather than capturing the entire frame at once.

Glitché App Intentionally Distorts Photos Into ‘Works of Digital Art’

Aberrations, distortions, corrupt images; all of these are things we typically try to avoid in the world of digital photography. But the Glitché app does the exact opposite. Instead of trying to remove digital imperfections from your photos, the app piles specific distortions on, and in the process turns your pristine pics into "works of digital art" ... at least that's what they're calling them.

Using a Prism for Creative Photo Effects

Have you ever considered adding a prism to your camera bag? Washington DC-based wedding photographer Sam Hurd has done quite a bit of experimentation using an equilateral prism -- the kind used in schools to teach properties of light -- to add special effects to his photographs. The results are pretty interesting.
