HERE’S THE BIG PICTURE WHO SCORES WHERE?
Although both tools are meant for working with your photos, but they take very different approaches to the problem, and which tool works best for you depends on what you are trying to achieve on the ipad. Photoshop Touch is oriented towards heavy editing and the ability to create new images from scratch, whereas iphoto is geared towards managing, tweaking and sharing images you already have. So while iphoto excels with easy tweaking effects and excellent Journal sharing capabilities, Photoshop Touch powers ahead with the ability to work with multiple effects on one image, cropping and selecting any shape (not just the rectangles that iphoto is limited to) and adding text to an image. But remember that both have their limitations too. While iphoto limits file sizes to 19 megapixel images and does not edit RAW uncompressed files, Photoshop Touch has slightly troubling size limitation, in that the program will resize images to fit a maximum resolution of 1600 by 1600 pixels and 16 layers. While that can be attributed to the increased performance demand of working with layers, this limitation restricts Photoshop Touch’s use to making images fit only for small prints or the Web, or for mock drafts on the go. It wont be killing CS5/CS6 on the desktop, that’s for sure.
