"D700, long exposure HDR" Mon 23-Apr-12 11:30 PM by RMangino
I've been doing HDR for quite some time and feel very comfortable with it. Lately though, I've been running into an issue when doing HDR at night (low light) - I normally shoot daylight HDRs.
I normally bracket like this: -2, -1, 0, +1, +2 (the number of frames varies).
What I am running into is that instead of getting a +2, and a +1, I end up with TWO +1s (two frames that were taken with the same exact, exact, shutter speed - 30s in this specific case). It is like I'm bumping up against a long exposure limit or something. Is this expected? Am I just doing something wrong?

That is exactly what you are hitting. The auto-exposure system maxes out at 30 seconds. You will need to adjust your "-2" calculations to be at the 30 second mark with everything adjusted higher/faster. (or go manual exposure using bulb?)
