Hello all. I'm a noob when it comes to photo/drawing apps and I have a question. I would like to cut and paste people and objects out of different photos and add them to a collage. I purchased Photoshop for the iPad which has layers, but it is very hard to cut around the person in the photo. Photoshop from what I can tell only lets you cut squares. You can't get precise with your cutting. What are some of the best apps that are great at precise cut and pasting? Something with layers would be good too. Thanks for your help!
