My favorite new iPhone app is PhotoTropedelic by Larry Weinberg ($1.99). I’ll say upfront that v1.0 auto-adds a credit to your photos – BOO for a paid app – but the developer heard the cries of his public and has submitted a 1.1 revision which he promises will eiminate this annoyance.
Here are a few originals and the PhotoTropedelic versions I created of them. Click each one for a larger image. For a one-button photo modifying app, it’s pretty sweet, don’t you think?
