SnapShot+ by Nao is currently free in the AppStore. It's a pretty basic shooter, but I've been playing around with the quality it puts out. Currently trying to compare the maximum quality of 1280x720 to that of Camera+ and ProCamera. Should be about the same, but it's always nice to check them out and see where you're getting the best quality. Also I don't know if it's been posted already but FX Photo Studio is currently 99 cents in the US App Store. Not sure what that translates to in Euros, but I'm sure others from overseas would know. It's a pretty solid editor with alot of filters that some may like. I find their best ones are the Hollywood FX set of filters, but they cost an extra fee. Last one is AutoPanorama. Literally just went free a few hours ago. Haven't played with it yet, but I will soon. Description says it puts up to 18 megapixels of clarity and it's free, so why not give it a shot?
