OK, getting back on track, here is Camera + for the iPhone, probably the one app for the iPhone you’ll ever need.
It’s done quite cleverly: it displays the picture of a DSLR (viewed from the back) on the iPhone screen to make it look like you’re looking at the LCD display at the back of a DSLR to select functions, then it zooms thru the viewfinder of the DSLR so you feel you’re looking thru one to take your pictures. Well done, Lisa [Bettany]!
