As I mentioned on the home page, the 4 steps that you need to master if your original photograph is a good representation of the item you are selling is to "Crop", "Rotate", "Resize" and "Save As". This can normally be done with either the software that came with your camera or a wonderful FREE software product called Irfanview (pronounced "EarfanView") . Click here to read more about Irfanview and download a copy. If your pictures need additional post production work, you can purchase several photo editing software packages. My favorite is Paint Shop Pro. 

If you use a Cloud Dome or some other product that takes great pictures, try the software that came with your digital camera. If that doesn't work, download a free copy of Irfanview and try that product. If you can get an excellent result from free software, that would be great. Again, if you don't have the right "studio" set-up, you will probably need to purchase a more expensive photo editing software product. I recommend looking for Paint Shop Pro at Amazon.com .
