You are right, its my poor memory. They prohibit you from touching the delicate formations, not from using flashThe local cave wardens would string up anyone using a flash. They supposedly do a lot of damage.
I have a hard time believing that. From what exactly, a few microseconds of photons? Open a cave to the noonday sun for a week and it will change things, but a flash doesn't make sense. And if so, then how is a headlamp supposed to be OK?QuoteThere are low level lights though, so my 5D MK II/ 35mmL worked just fine.
I probably would have done better if I could have stopped. I was with a group that was marching forward.QuoteGardner cave in NE Washington State up near the Canadian Border. Sorry for the poor photoshop job, I removed some obstructions from the image, and its a poor job.
Nice, I'll have to visit it next time I'm up there.
If you are ever up here, drop a e-mail and we might be able to meet.
Here is some damage, I thought the guide said it was from bright lights letting the alge grow.
Setting up a tripod - just too many people in a group, and not enough room on any flat places. Mistly, the descent is on narrow and steep stairs cut into the rock, or steel stairs. A monopod should work though.
The 35mm L and 5D Mark II worked very well, but in some places, a flash would have been needed. I restricted my photos to areas close to a light.
A small side vent that probably goes to the surface somewhere in the trees and rocks above. The cave has been pretty well explored and documented over the years, but I only have my recollection of what the guide said.
