When I started shooting mostly RAW it spoiled the fun of editing photos on my iPad. The iPad imports RAW but you really cant do much with the photos except store them and transfer them to your computer. This app changes that. I mainly use the app to convert my RAW shots to JPEG (although you can do some basic edining in the app). I can then edit the JPEGs with a variety of other, very capable photo editing apps. If theres a shot I really like I can edit the original RAW on my Mac. I have a Canon S95 and a Panasonic G1 and both RAW formats import into the app without prpblem. I did have some issues with the app becoming non-responsive after exporting to JPEG but after restarting my iPad the problems went away. In trying to figure out the problem I found the developer to be very responsive with email. There are some improvments that Id like to see and the developer said they will be comming over the next several releases. Top among them for me are: - Ability to select multiple photos and have them automatically export one after the other. - Less sensitive in-app image manipulation controls. Currently, a small movement of the slider prduces a BIG effect. - Ability to restore to the original RAW after manipulating an image. One word of caution. RAW images are large and the app takes a while to import a photo, about a minute for a 10 MByte image on my iPad 1. The developer said the next release will bring significant performance improvements. But I expect the times to remain in the 20 to 40 sec range for some time to come, perhaps much faster on the iPad 2. All in all the app provides important functions for RAW shooters and I look forward to its evolution.
