Plein Air Painters of Oregon has a winter challenge contest. We were given 3 black and white photos and left to interpret them ourselves. Actually, as a past board member I was the one to submit the photos. But I dutifully did this painting from black and white (not even sure I could fine the color photo in my photo reference, had I wanted to cheat)...and it was a lot of fun. The problem with painting from a color photo is that the photo is often off, and the painter subconsciously tries to replicate the mistakes of the photo resulting in an off painting. I suspect the original had green grass, but I really wanted to capture a late autumn day (bare foliage, warm colors just before the winter cold).
