I tried cleaning up DSC_0034_good_1, and posted the PNG to Imageshack:
The original XCF is available at
MediaFire.
Overall, this was a really good product photo! Three suggestions:
1. Use two or more light sources for your lightbox, so you don't get such a sharp shadow. I tried cleaning it up and got it how I liked it.
2. Clean the Pandora really well first. Go at it with both compressed air and electronics cleaning wipes, should run you ~$10 at any decent electronics store (that's about a pound-twenty, for our friends across the pond). I got the largest of the smudges off and some of the specs, but cleaning it all takes more patience than I have at the moment.
3. If you can put your camera on a tripod, take the same picture with different focuses so you get everything in focus, over multiple pictures. Any decent photo editor should have no trouble combining the set of images to get everything in focus. I played with the contrast and the sharpening tools to get both the SD card and the pen in focus. I think I overdid the pen a little though.
Edit 1: Removed comma splice.
Edit 2: Brightened the screenshot (technically, increased the luminosity, but who's keeping count?).
