Thanks Ofnuts; I'm now investigating this tool.
Okay ... I think that I have understood it.
The scale is 256.
Therefore a fully black image would have a value of 0
A slightly less black image might have a value of 2.56
This would indicate that the slightly less black image was emitting 1% of light
... and absorbing 99% of light.
This is the required tool.
Thanks again Ofnut
