I have listed two photographers sites on this page.
I have used both to help me understand Photoshop and Lightroom. Both are great
programs, but can be a bit daunting. Having photographers that are so generous
with their knowledge is a great help and I can not state on this page how much I
have learned from them.
If you need some pointers, I am sure that either
will have information on their sites, they are masters. My personal thanks to
