That would be perfect for ocean scenes and rolex scenes :) I can't 
imagine lining the image up 'in scene' though... sounds very difficult. 
Can you post a link to an example of your technique?

Yes. I have to first place the #declared image_map inside a 
pigment_pattern block, which makes it grayscale. With that map I am able 
to make the darks parts transparent and the light parts colored with my 
original image_map. I blur the result over a plane with the original 
image_map, untouched. I am thinking of releasing the code, but it has to 
be cleaned up quite a bit.
