I have made a crazy purchase for my trip... a cable release and a little gripper tripod. I am not a puritan of any kind when it comes to photography, but I have opted for handheld at all times and have always felt that a tripod, and most certainly a cable release, were a little too fussy for me. I vote for balancing the camera on the car roof, or whatever is around, to keep it still. And I up the ISO to prevent shake, so noise can often can be a factor. That's the way I like to shoot and if I miss a shot, so be it.
The no flash Power/Ower photos were all made with a high iso and prayers of minimal shake and they are a ringing endorsement of the ability to show what I want using no more equipment than the camera.
But up here it's dark. It's dark A LOT. So I decided that I would have to prepare for a place where much work would be done in a twilight like daytime and the out and out night.
