Newbie question and I'm sure it's probably been asked before, but I cannot find a definitive answer.
I only have a remote shutter release for my DSLR and using a stop watch for how long I want to take the shot.
To take dark and lights, do the times have to to exact for each shot?
If the shots are 1 sec or 1/2 sec off of each other is that ok and will you still be able to stack/ process the images, etc correctly if the times are slightly off ?
Thank you for any responses on this.
