Adobe Photoshop Express
The granddaddy of all image manipulation programs is indisputably Adobe Photoshop. In fact, the very name of the product has become synonymous with photo editing. Fortunately for iPhone users. Adobe has released a smaller version of this beast, without the painful Photoshop price tag (it’s free!). No, you can’t use this app to put George Clooney’s head on your husband, but you CAN use it to adjust the exposure, saturation, and tint of your photos. I find it especially useful when I need to quickly crop a photo I took with my iPhone. The app includes a few presets for special effects, although those functions are better served by other apps. In a nutshell, you NEED to have PS Mobile on your iPhone for small, subtle fixes to just about every photo you take.
