I was wondering too and looked at it, finding it broken in a few
trivial ways (details coming soon to a ChangeLog Near You!)
Input: 1. a desaturated RGB image
2a. a gradient OR
2b. an image with some saturated colors; it derives a gradient
from such an image.
What it does:
Lets say the gradient (2a|b. however derived) ranges from red to cyan with
grey in the middle range.
The plugin colorizes the desaturated image in accordance with the gradient,
so:
1. The shadows of the desaturated image colorize red
2. The midtones of the desaturated image colorize gray (which is not much at all ;)
3. The highlights of the desaturated image colorize cyan
There are Image/Color/Level controls so mapping is not exactly linear
and a few other toys that noisify the mapping that one can play with;
these will be functioning when I commit the fixes (tomorrow, I think).
Personally, I think similiar tricks may be pulled fully in the confines
of the Curve tool, but as Marc pointed out, not everyone is a copy of me
(or is it 'a copy of Daniel Egger'? I forget ... ;), so some people
may find this plug-in to be lots and lots of fun.
Be good, be well
