Hey everyone! I'm slowly getting back into photography, more astrophotography, but some terrestrial shots too with my older D5000. My question is this, I need to shoot 15 sec exposures, and have been playing with the interval timer settings but I'm confused. The interval is supposed to be the amount of time in between each shot which I have set at 3 seconds. The number of intervals are to be the amount of shots I would like at 15 seconds, which for my test I chose 100. Here's the kicker, I only got 14 shots before it stopped itself. I tried different settings and all of which did not give me the asked for number of shots. Like 3 sec exposures were set 3 sec apart for 15 shots and it stopped at 8. Any help is greatly appreciated!
Oh, NR is turned off as is High ISO NR.
