I have had some problems lighting my white background evenly. I'm using a P&S and whatever I can find around the house. I got a good shot but when I resized to submit I see some "banding" of the background. It looked fine on my regular monitor but it is really noticable on my laptop. I am not PS expert and I don't dare mess with the levels any more than I already have for fear of messing up the subject. Is there anything I can do in PS to correct the background and not alter the subject within the rules?

Danny, if your camera offers a real-time histogram, make sure you expose so the data is as far to the right as possible without touching the edge. This probably means you will need to overexpose by about a stop or two.

You should be able to do this by adjusting your EV setting.

Curve are more accurate and are not damaging quality on your file like levels do for large printing when I am talking about over 120 cm, you can find articles on web by expert and it is working for me but you need to find small advice to work on curve do to my language barrier I cant explain it truly to you all but look it up on the net :)

levels have at most three control points which will shift the output by changeing the white point , black point and where the middle (18%) grey point is.
curves can have multiple points (16? in ps) and the ability to control smaller areas of the contrast map.

hmm, I think I'll stick to levels right now... only 3 things I can screw up rather than 16, haha!
