Gotcha Hamish - thanks. I suppose it really IS to do with pre-visulisation when you first capture the image. I fully understand now . Thanks very much.

David,

I apply pigment all over the image ­ with the seaweed image the negative was
made to ensure that the sand would require much more exposure than the
plant. Getting that right took some time but it allowed the beach exposure
to be made and fully printed, followed by the exposure for the plant which
was also fully printed but the exposure difference made it easy to remove
the green pigment & gum from the beach part of the image.
