good question Wander...
i just googled (hav'nt looked up CAA yet)...and came up with some info try AirSafe.com. it says cameras are not in the prohibited list but it seems to be recommend practice for US carriers that digital cameras (and other things) are allowed above 10,000 on the climb and until the approach phase (typically 15 minutes)....other than that there does not appear (so far as i am aware) any operational reason for not being able to use a camera...subject as always to correction...
