Canyoning: How did he get that shot?

I don't often have another photographer along when I am shooting, but on a recent canyoning trip Rich Crowder a American photographer and climber made some photos of me making photos. You can look at my previous post about descending Juggler Canyon (Here) to see some of the photos I was taking when Rich took these photos of me shooting photos. Can you figure out comparing our photos where he shot his photos. You can actually see Rich in each photo. 

In this Rich Crowder photo he was looking down at me at the top of the rappel as I was shooting away perched on a slimy ledge above a deep pool of water. I was using a Lastolight ezybox with a Nikon SB-900 attached with a TTL cord to my Nikon D-300s the lighting was figured on manual and the camera settings were something like 1/50 at f5.6 at asa 1000. There was no way I could look through the view finder because I was leaning back to keep from falling off the ledge into the pool. 

Here's Rich's next photo of me setting up for a photo at the falls near the canyon exit.

Remember when you were just starting out in photography and to shoot a long time exposure or a self portrait you would place your camera on the ground and stack twigs and rocks under the lens so you could get the right angle for the photo?  And while trying to get the pebbles and sticks to stack correctly under the camera you were thinking, man one day I going to get one of those flashy tripods like the pros use. Well pros like me still have to resort to rocks and twigs every once in awhile. That's what I am doing here and the result seen in my previous post (here) shows that the camera was as rock steady as if locked onto my fancy heavy carbon fiber Gitzo tripod that I wisely left at home. The camera I am setting up using sticks and stones is the Nikon D-300s with a 16-35 f4 lens and a Moose warming polariser filter. Thanks Rich for sharing the photos.
