You can reduce such problems by simply keeping the camera back away from
the fish - use a telephoto lens.

Thank you very much for all the help, it gives me a lot to go on.
I have one specific query for now. I am concerned that in taking an image of a
fish of 40 cm, that distortion may take place (i.e. the part of the fish
directly
under the camera will be closer to the lense than the parts of the fish near the
edge of the field of view). Is this likely to be a problem at the scale of a 40
cm
fish or not really worth worrying about?
Thanks again,
Cheers,
Darren

Hi there,
I am just starting out with geometric morphometrics, so was hoping someone
could point me towards any documents that could get me started.
My specific query is around the image taking process. This is because I may not
be able to analyse the images for some time (images will be of fish ~ 40 cm in
length). So, for now, I would like to ensure that I take images that will allow
me
to do 2D analysis later on. Is there a document/book/previous string of postings
that outlines the best image taking process/equipment in simple terms? I have
"Zelditch, Geometric morphometrics for biologists : a primer" on order from my
library?
Any help would be greatly appreciated.
Thanks,
Darren
