Please help!

I have a collection of photos of mammal skulls that I took for
morphometric analysis. But now I got new specimens of the same
species that I would like to include into the already mentioned analysis.

The problem is, I can't photograph new specimens under the exact
conditions I photographed the first. Especially the DISTANCE of the
camera from the skull is the problem. I can't photo the old again
because they have been borrowed from many different museums and have
already been returned.

What shall I do? I need to calculate CENTROID SIZE for all specimens. Is
this possible? I also don't have any scale on the old photos, but I know
the exact length and width of every skull, is this enough?

Please help me. I don' want all my old photos to go to waste.

Thank you in advance!

Tina
