It really did make a difference. I did notice that the white wings were never really snow white and had a dingy grey tone to them. I always thought it was my lights (I use premade ones only). Since I did that "reverse normals" for the groups, it's made all the difference. White wings are really white wings! LOL Dan, that is a wonderful image. I'm sorry about your Dad :( Both of my parents are deceased and that moved me.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
