Like many photographers I shoot my fair share of photos with my iPhone but to get the black and white look that I like in the past I've always had to post process the image in Snapseed or other editing app. While I do love Snapseed it is an extra step and MPro seems to have solved this for me. MPro is a monochrome photo app that shoots only in black and white. In fact it saves in greyscale rather than RGB which results in a different black and white look that I like. In addition to that it has an onscreen contrast slider to add contrast to the image with real time feedback on the screen before you even take the shot. Sweet! Right? Oh and it's only 99 cents. Here's the link to the app on the iTunes store.
