Dear Ecology List Server, Thanks for your answers to my question. I have a couple of further questions. Q. Do you think it is nessescary to use the same camera, strobe set up? These are historical photos so if I use a photo of known area it is likely to have a different set up. Q. What do you do if the photos were taken at different distances from the sea bed? Cheers Beth Strain
