I take a lot of HDR images for vfx work. I’m on a quest for the perfect setup that is super fast to use on set. Here are some of the things I’m looking at.

Everything HDR hdrlabs.com

Mod your canon firmware…. including hdr video which is just nuts frankly using Magic Lantern firmware

Some links for auto bracketing exposures. Using software or remote control http://www.dslrassistant.com/

Control your camera using a scripting language HDRCapOSX

expensive do everything dslr remote control promote

There’s also OnOne’s dSLR Remote for the iPhone … unfortunately you still need a laptop to connect to your camera and run the software. But it has some useful applications.
