I've never shot long exposures before, but I've been shooting RAW since first started out. I have never noticed this before, but when shooting for 30secs, 90 secs etc, after the shutter has closed again, the camera takes nearly the same amount of time the shot took to write it to memory (didnt' actually measure the time, but roughly). So for a 30sec shot, it takes around another 30secs to write to card, doubling the time.
I'm worried if/when I start attempting 30min star trails etc, they're each actually going to take an hour each and so on.
Haven't tried shooting JPG to see if it's the same thing.
Do you all shoot RAW? If not, is the above the reason or something else?
Main reason I have always shot RAW is better control of exposure and white balance etc, and also treat those files like negatives. But with astrophotography, maybe exposure and white balance aren't as much a factor due to the subject? Not sure. (Of course exposure is important, but what I mean is it's not like someone's face is underexposed, we're talking about white dots on a black background anyway - that make sense?)
