Not sure how you could do this with a Sony A350, I have had good success with a canon 60mm macro lens, I made a tube out of black card to fit over the lens sandwiched the film between two black cards with a hole the same size of a picture this was fitted at the other end of the tube, with this being fixed to the lens you can hand hold it without getting any movement blur and aim the camera towards natural light like a bright sky, I can’t show you a picture of it because I have mislaid it but I could knock another up to show you what it looks like?
