I am glad you like the portrait of my beautiful wife. There are four secrets of how I did this painting:
1. I knew the person who's portrait I was going to paint very well. 2. A lot of patience taking the portrait photos. 3. I took the two photos that reminded me most of her. Then morphed them and found a place between them that was closer to my idea of her. Then I found a third photo I could morph with the morphed version to get even closer to my idea of the essens of my wife. 4. I spend a lot of time painting it. I just used the final morphed photo to refer to. No projector or other tehcniqally help at that time.
