I will be camping this weekend and the nights will hopefully be dark enough to try some star trail photography.
How to set up the camera.
I have a 5dmk3.
70-200f 2.8is.
A 24-105 F4
A Giga t to keep the shutter open.
Heavy tripod.
When I tried this before, after keeping the shutter open for about 30mins, the red light stayed on the camera for quite a while as it processed the image. The battery then died. How long does it take for the camera to process the image? Is it normal, to wait a long while?
I would think I set the camera up with the lens wide open, maybe iso 400? How much time do you allow to get the full rotation.
Someone said you set the camera up facing north.
