Having an "essential tremor" in the right arm does not bode well for a hobby in photography. But as I've got the bug I might as well admit that I am the Shaky Photographer. High speed film is definitely my friend.
As part of my arsenal of gear I have a monopod and a few tripods of various sizes. Even a hiking pole with a bolt on top for a quick camera connection. Any solid object nearby is a handy spot to steady the camera with. When I am out night shooting wildlife I have the monopod extended from the Metz flash ready to plant on the ground. It helps but looking through my 300mm lens would give a pro photographer kittens. For me it's take a shot and pot luck. Looking forward to setting up the Nikon FE with the 125 flash sync. The timers get a work out too. On longer times I still don't trust my shakes so I often set the timer and steady the camera till it fires. The Nikon is awesome for this as when the timer is triggered it flips up the mirror immediately and holds it till the shot is fired.
