As a growing and exciting art movement, iPhoneography is fast becoming a way for anyone with an iPhone to express their creative side. It's now easy to take photos and then tweak, enhance or transform them into works of art just by using a careful selection of apps. It's hard to believe that the iPhone was only first introduced to us back in January 2007. In the past four or so years, we've seen Apple release four different generations of the iPhone, each packed with more features than the last. The latest generation, the iPhone 4, now comes equipped with a 5-megapixel built-in camera with optional HDR and an LED flash. Today, we've collected for you, some of the most beautiful and inspiring iPhone photography out there. These 25 have been chosen because they show a wide range of effects. (Can you believe that all of this can be done with apps?) Click into them if you'd like to know exactly which app these photographers used. (Most of the time, they'll share that information with you, especially in their tags.) Finally, if you have an iPhone and want to know which to download and spend your money on, here's our list of Top 10 Apps to Make Your Photos Pop!
