Those of you who own long lenses might want to give this five-and-a-half minute video a watch.

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.

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.
We’ve written a couple of times in the past on how you can achieve drastically different portrait looks by choosing different lens focal lengths and subject distances. Basically, your choice of glass can make a huge impact on what your subject’s face looks like… and how much they appear to weigh.
You’ve probably heard before that focal lengths between 85mm and 135mm produce the best head shots because they provide a desirable perspective in head shots, but how much of a different does the focal length actually make?

Tom Hogarty, the Lightroom product manager over at Adobe, has posted a sneak peek at the automatic lens correction technology that will be included in Lightroom 3 and Adobe Camera Raw 6 (included in CS5).
Using profiles for lenses that are either included or added by the user, the feature can automatically correct the distortion, chromatic aberration, and vignetting characteristics of particular lenses, helping you to “normalize” how your work looks across your various lenses.
John Ncak, the Photoshop product manager, writes on his blog:
With the introduction of killer new noise reduction, demosaicing algorithms, and sharpening plus sophisticated lens correction, the Lightroom/Camera Raw duo put even more distance between themselves and the competition, and I’d expect them to keep mopping the floor with Aperture among pro photographers.
As you can see from this quote and from recent events, Adobe and Apple absolutely love each other.
Here’s a pretty interesting sneak peek video showing you the lens correction technology in action:
