That's it! Perfect.
glad to hear it works as expected. Just want to add that the programmer's route,
aka doing it by the math, is quite viable, too. Some selected options:
- the MathMap plugin probably enables the most concise solution:
Duplicate layer, invert bottom layer and cut all blacks and whites out
of (transparent) top layer (of course, if there's a range of greys it
gets more complicated).
it's evident that this is the problem : i don't know about Rich's photo
but the sample i use here have various flavors of blacks'.

i.e. invert pixeils with a saturation of ~0 (if that is how you say

I used to do it in CMYK a long time ago with photoshop by just pushing
the image to CMYK and inverting the K curve.
