Wayne, it's the photo editing program that came on the computer. It does work pretty well to get rid of bases. It takes a little practice I guess, but I've been doing it for years now and have gotten the hang of it.
Thanks. If you allow your camera to take on default, it's probably using a low aperture number like 4 to 7 or something like that. That means that what it is focused on will be in sharp focus, but what's in the background will not.
If you want to get the background to be in more focus along with the main subject, you have to use a higher aperture number setting. I do this manually on my camera. The photos I make that have a clear/in focus background are usually taken with an aperture setting of anywhere from around 18 to 29.
There is a tradeoff though.... you have to have the camera almost perfectly steady when taking photos with a high aperture setting or they will not be in focus. You also must have ample light or the high settings do not work as well.
Hope this helps.
