4 June 2013Camera Noir, App Store:
Camera Noir features a monochrome filter with three carefully-tuned settings that let you see the world in a classic way. You can easily shift focus and adjust exposure by tapping on your screen. Make sure nothing is left out of Instagram with square crop marks. And with the built-in level line, you know when your photos are balanced. You can even import existing photos from your camera roll.
How do you know this is a really great app? It has a really great website.
