John,
Seven years ago, I had a special computer built for my amateur photographer/videographer wife. It had some specilized software from Dell.
Just last week I replaced it with another special built Dell computer. I bought it with Adobe Photoshop Elements 8 for her photography.
I also bought Adobe Premiere Elements 8 for her videography.
I talked with a number of knowledgeable friends including one who is a professional photographer and Photoshop Elements was the recommended software by all.
I have played with the program a little and it seems to be pretty intuitive so I think my computer challenged wife will be able to comfortably and easily use it.
