Chris says the best way to scan your prints, is to scan the negatives, rather than the prints.
This week's photo superpower is how to "shoot appealing photo shots." You can make up to 30% more with a good photo of something you're trying to sell. Keep your image simple. Keep the distractions at bay by having nothing but your product in the image. Put a sheet of plain white paper behind it to mask out everything else. Some use a laptop and tape the paper on it, having it curl across the keyboard. Have it lit well. Hard light will not make it look well, so you want a nice soft light that enhances the image, not blows it out with harsh shadows. A light tent is a very good way to do this, because it can envelope the subject with a nice glow. If you're selling something large, maybe wait until an overcast day. Use manual white balance to make the colors look nice. You want it set to the light conditions you're in.
Don't forget our current assignment - SQUARE. Take a photo of, about or otherwise concerning the concept of "Square" and then post it to the Tech Guy Group on Flickr. Make sure to tag it with the word "Square" as well! And if Chris likes it, it could end up on next month's photo contest review segment!
