I have been working on a painting from Velazquez and there is a part of it I can't get right. This is the reflection in the mirror. You can see the original painting here: http://en.wikipedia.org/wiki/File:RokebyVenus.jpg
The painting is all done and I'm very happy with the results...except for the face
I must have done this over 10 times now. Wiping off the canvas and starting over and over. On the original it is very smudgy and I have had the inside of the mirror photograph developed several times but it's so dark that I have a hard time to differentiate the colors on the dark and shiny photo.
I know some of you are Photoshop wizard. Can someone do a polarized version of this to help me see where the colors are and what they are? Or maybe someone can give me some trick on how to proceed for this section.
