We did sort of do this thread once before, but it is a good topic and we have some new people. I guess sometimes I use all of the techniques mentioned so far... What I really like about Wolfie's presentation here is that the thought process is tied to a specific example. "This is the thinking I went through to create this image." I'd really like to see more of this done here. I think it would be a way for all of us to learn from each other.
