Sometimes it's better to put the photography second and focus on the experience. I'm was a nervous about taking the DSLR swimming in a slot canyon. We were pretty green at this canyoneering thing. Hey we have backpacks, harness, wet suit and an alpine climbing rope. Should work right? Had a ton of fun, nothing lost, no one hurt. That's a successful day in my book. But I did bring a point-n-shoot to "document" this little trip.
