5d3: HDR VS Multiple Expsosure vs AEB
rocket_scientist:
The more room you give yourself, the better. Depending on the scene, 3 exposures might not be enough. Some scenes need many more than that. Make sure you are shooting in raw and in manual. The histogram is your friend, along with the high light alert. If you have a lot of time, with a still subject, you begin by exposing the darkest exposure that the highlight alert just shows up with white flashing. You then begin to systematically increase your exposure, using the shutter, not the aperture, by 1-2 stops each time. After you take the shot, look at the histogram and when the left side of the histogram begins to go flat (i.e. there are no more vertical lines), you have captured most of the dynamic range of the scene. This could be any number of exposures. I have done this and have been very pleased with the results. If your title is correct, you have a 5D mk III and that allows 7 frame AEB which I would recommend if you don't want to take the time for the above procedure as I said: the more range you give yourself, the better off you will be. To give you some insight though, before I knew of the above technique, I used the AEB on my 7D with +,- 2 stops for this picture in Sandusky, OH.

If forgot to ask:
- Is it better to shoot M or Av? The 5D3 supports both HDR and AEB in both modes.
- Do you use mirror lock when shooting these scenes along with a remote shutter?

I usually shoot Av, if for some reason the centered metered shot looks off then I shoot M. Also I was playing around with doing it handheld (as opposed to tripoded), and Nik Software's HDR Effex for CS6 did a great job of aligning the images, even when I shot 9 images and intentionally moved the camera around a bit. CS6 does not do as good of job natively in my experience of aligning the images, but others may differ with me on that.

I usually meter in Av (usually at f/8 or f/11), and then shoot in M.
I don't use mirror lock. I shoot in High speed, usually with a remote timer.
As is the case with panoramas, I usually shoot landscapes in Cloudy or Faithful, but not Auto.

When you say High Speed you are referring to the 'Drive Mode' of 'High Speed Continuous'?
