And to answer the original question:
- 5D Mark II and various lenses / accessories
- Full-sized tripod (eyeing a mini-tripod one of these days)
- Slingshot camera bag
- Lenser HP14 flashlight (primary)
- Lenser HP7 flashlight (backup)
- couple of granola bars
- water bottle
- gloves (
these ones)
- bog roll
If I'm draining or somewhere else where it's really dark, I bring along a bunch of flashlights mounted on small gorillapods to set up my shots.
