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.
A 24-105 F4
A Giga t to keep the open.
When I tried this before, after keeping the open for about 30mins, the red 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 wide open, maybe 400? How much time do you allow to get the full rotation.
Someone said you set the camera up facing north.
