Thanks Toby and Lois! That one's very cool Lois.
Yea, it is great fun! I kind of get why George Lucas revised the original Star Wars movies. I've been playing a bit with Split Toning lately. I used to think it was a B/W or monochrome tool, but I'm finding it can do some amazing things with color images as well.
Chris, that one really has an interesting quality to it. Though if you really wanted to you could easily change the color cast. Personally I'd leave it. It's very unique.
