Finally! Perspective Control Right on My iPhone
Here's a photo I shot with my iPhone in Wisconsin Dells last month from a moving car. It used to be that if I wanted to do something like making the ramp and the telephone pole truly vertical, without converging lines, I would have to export to Photoshop -- and it usually wasn't worth it. Now i can do it on my iPhone (right), thanks to an app called Perspective Correct. (It can also be used live, while shooting.) And it's very easy and intuitive to use.
Perspective control is most often used for architectural photography, and pros normally use either a view camera with a lens that shifts or an expensive perspective control lens that can run many thousands of dollars. Software, whether Photoshop or an iPhone app, can mimic the same effect at much less expense. (The drawback is that perspective control in software creates artifacts that show up in big prints; it also involves drastic cropping.)
But if you're shooting for the web or not making gigantic prints, this software tool is a valuable resource. It can make a snapshot pop and look like something shot on a view camera, because the perspective is so unusual. It can make your travel shots of buildings look more professional. And, if your makeup, like mine, includes a bit of OCD, it's just plain fun to play with.
Now my digital-darkroom-in-a-phone is just about complete.
