Here's a new one:
Haven't tried it yet, but will certainly give the demo a run through.
I must admit the for "normal" shots, I quite enjoy manually tweaking colour balance etc. But sometimes this can become a real chore - this weekend I shot a local Xmas fair in a church hall - mixed flourescent, tungsten and natural light. A colour nightmare, and, because I was moving around, the balance of the various light sources was changing in every pic, so no batch processing of the shots was possible.
Standard PS tools (Auto-whatever) really can't handle this sort of thing, and colour correcting manually is tedious to say the least. Tools like Colorwasher are a real blessing when faced with this situation and worth every penny.
