My D90 only brackets one exposure each + and - (3 total). Anyone doing HDR with a D90, or other limited camera, how do you get 5 exposures without a lot of screwing around? I really don't want to touch it once the tripod is set. I would like 5 shots that are 2 stops apart.
What I personally do is use the exposure compensation. (I have a Canon myself, so exposure compensation for me is just one flick at the big wheel. For your camera you need to press a button in combination with a dial, so it is a little bit more cumbersome). Set the exposure compensation to -2 for your first batch. Then you get three shots:
-4 -2 0
Then set the exposure compensation to +2 and start your next batch. You then get the shots:
0 +2 +4
So you end up with one double shot, but you have 5 shots with two stops between them. It might not be what you are looking for; you still have to touch the camera between the two batches. Nevertheless I think this is the minimal effort to do it in-camera.
