Spica - Super Monochrome is a camera application that allows you to take a super strong black-and-white contrast photo. The black and white sharpness of the picture will clearly show up the lights, shadows and texture of an object, and creates beautiful pictures with a great atmosphere.

Spica is very simple to use. Get a slight of an object you'd like to take a picture, then just tap the shutter button! Taken pictures will be automatically transformed into a super high contrast black and white photo and saved right on your iPhone.
