Ive been waiting for this combo app and here it is

I love posting photos on Instagram and have used various photo editors that work well. But this is the first time Ive been able to download a powerful manual camera app for my 7+ along with an equally powerful photo editor. Im raring to learn the manual camera controls, which look really easy. Imagine ... being able to adjust my shutter speed and multiple exposure levels on the fly!
