I used to shoot 7 - 9 frames to get best HDR results with a D300 or D700. Between the D800e and CS6, I can now do the same with 1 - 5 frames. Yes, I said 1. About half of my HDR shots result in me using just one frame. I can get great results in high contrast scenes with less work than I could ever get before.
The level of details in my bird shots allows me to crop to 10-25% of the frame with no worries.
Now that I have learned to shoot birds flying while hand holding, I am in pig heaven! No more tripod legs to trip over and drag around on the beach.
Unlike Eric, I try to stop increasing ISO when I hit 1,000. While the details and dynamic range are still there, I don't like to work so hard to get the noise out without hurting details.
