Dear Dimitar,
I am a undergraduate studant in Brazil and I work with benthic ecology with
photographic sampling and we use CPCe. We used a DSLR Canon 300D with a
18-55mm lens in the first two years, but we choose to change the equipment
to a compact camera.
Theres some advantages work with compact cameras:
It's Cheaper
The maintenance is easier and faster
The kit needs less space (in the boat for instance)
You can take great pictures with high definition using a Canon G9/G10.
I think the most important thing is the lighting. If you have 2 strobes your
sampling and the quality of you data will be very good.
Of course the quality of the pictures of a DSLR are much better. If you have
plains to make other kind of photography DSLR are the better choice, but if
you want the equipment only for your project sampling a compact camera will
supply your demand very well.
For my personal work (as photographer) I use a Canon 400D with Ikelite
housing and strobe.
