Ace stuff in the colour-department as ussual Josh.

At first I wondered why he seemed to be missing parts, but then it dawned on me: he's de-cloaking!
I've been meaning to ask you, do you use a special layer for shades, set to multiply like I do?

Or do you do that thing with dodge and Burn tools, straight on the colour-layer?
Also, what is preferrable, the easier quicker way of paint-blobs, or cut-selection and paint-bucket when doing shades?
