Thanks for these interesting replies. I had a feeling I was asking a difficult question but it is a bit surprising that a standard method has not been worked out previously. To get an approximate answer with my gear I think I will image a feint object and adjust the relative exposure times until I get a similar quality image. The difference in exposure times would then give me an approximate answer to my question? Cheers Peter
