Hey guys, I've been using the camera to take pictures of documents on auto mode. I noticed that sometimes that somtimes it crops things properly and sometimes doesn't do it at all. I've tried to be steady but it just doesn't do it. Any reason why? For example I take a picture of a health ID card it crops it perfectly and then I took a picture of a different card and it just refuses to crop it. On another note. What is the difference between saving the pictures as a document, picutre, coloured picture etc? Thanks in advance!
