Hi Steph,
A couple of things to look out for from my experience:
* Try to purchase a camera with a full-frame sensor. This is a
requirement for fisheye lenses used in glare analysis.
* The range of shutter speeds can make a difference as well for the
measure of very high luminances (1/4000s vs 1/8000s).
Beyond those two use cases, any camera with a manual mode that can
adjust the shutter speed quickly will work fine. I recommend to adjust
the shutter speed by hand or computer control rather than to rely on
auto-bracketing. Still, if you want to go the auto-bracketing route, you
may consider a camera that supports a firmware hack like Magic Lantern
which gives better bracketing capacity to cheaper DSLR cameras.
Otherwise you'll end up needing to buy an EOS 5D or something in a
similar price range for a good bracketing functionality.
Best,
Alstan

Hi, I'm new in this group,
We are about to get a DSLR camera for working with HDR and evaluate
glare in buildings as part of a University project. Can somebody here
give me some orientation about the specific features of the camera
that we should look into, for a good performance HDR images?
I think that one is that it should be possible to lock the flash to
prevent its activation in a darkened environment, another one is that
the camera should be able to take continuous images, and an exposure
bracketing system to be able to increase/decrease the exposure
(±3 EV), this can be manual but auto bracketing is better.
Is there anything else that we should check before ?
I'd appreciate your help
Steph
