Photoshop is a great tool if used correctly and sparingly, if not it can be a hot mess. So while tinkering(successfully) with my iPad recently I came across a free app PS Express. I used the free and basic edit to enhance and change the colors on these pictures of the Boylston T stop in Boston. Amy and I took these pictures one night during a class assignment. The photos on the left are the original and the Photoshop on the right and bottom. I am quiet impressed and I am upgrading the app, with new purchases.
