My father just signed up on Facebook last week. Now that he's looked at his friends' walls / pages posting old photographs, he wanted to do the same. I have been helping him to use the smartphone (and thus the FB account), but I am not good at all with using the camera feature, so I cannot help him there.
My question is, how to snap an old hard-copy photo using a smartphone that looks like it was scanned over a scanner (no shadow, no flash spots, no fingers at the edges etc)?
