Hi Everyone,
As it turned out, I wasted 2 hours after midnight last night taking 200 pics of the lovely night sky, only to find that when I went to my D7100 this am to process the pictures to create a star trail, I found that after the first 7 exposures, the next 30 were underexposed, then I would get one at the correct exposure, then another 30 underexposed and so on.
I was using my 18-55 lens set on manual, Camera mirror up, a user setting on the camera that has an ISO of 5000, the aperture at 3.5 and the exposure at Bulb. I then have a remote intervalometer that is set to take a 30sec exposure picture with a delay of 7 seconds between each.
Any ideas as to why after the first few, I would get only 1 in 30 ok ?
Thanks, Nige.
