I have about 12 third party camera apps, and I just purchased ProShot.
ProShot is now my favorite; I recommend this app as is.
In Addition to the 12 apps, I use two pro Canon SLRs, high end PC Photo Editors, and Print my own with commercial quality Epson Printer on high end papers.
So, this App is a no brainer.
Follow up: I am revisiting this review because I an still so impressed by the app. Until another app surpasses this selection, ProShot is the go to app for iPhone shooters.
