Can a Nikon D700 auto-bracket by aperture, and can it rename bracketed files by exposure?

I'm using a Nikon D700 for the first time and need to photograph mounted 35mm slides. I want to capture three bracketed exposures for each slide. Ideally I would keep the aperture at the sharpest setting (for example f/5.6) and take one normal, one underexposed, and one overexposed frame.

Can the D700 do automatic bracketing by changing aperture instead of shutter speed? Also, can it automatically name files in a sequence such as IMG_001-1, IMG_001-2, IMG_001-3 for each bracketed set?

If you shoot in Manual or Aperture Priority mode, the D700 will adjust the shutter speed. If you are in Shutter Priority, it will adjust the aperture.

It's unusual to shoot HDR with varying aperture, as the changing DOF can cause unwanted effects. I guess DOF isn't really a consideration in what you're doing, but still - if f/5.6 is the sharpest, I would imagine you would use that for all three shots and just vary the shutter speed.

I don't know much about digitizing slides, but I would imagine the dynamic range you are trying to capture doesn't warrant HDR either, does it?

I don't think you can name the files automatically like you want, but you can change the order of the bracketed shots. I think be default it's the metered exposure first, followed by the underexposed one, then over exposed one (assuming a set of 3). You can change this to under-, metered, over if that's preferable.

On the D700, auto bracketing changes different settings depending on exposure mode:

  • In Manual or Aperture Priority, it varies shutter speed.
  • In Shutter Priority, it varies aperture.

For your use, bracketing by shutter speed is the better choice. Changing aperture changes depth of field and can introduce unwanted differences between frames. If f/5.6 is the sharpest aperture for the setup, keep it there and bracket exposure with shutter speed instead.

Also, for slide duplication, HDR may not even be necessary depending on the slide’s dynamic range, but if you do bracket, keeping aperture fixed is the safer approach.

As for filenames, the D700 does not automatically rename files into grouped bracket-style names like IMG_001-1, IMG_001-2, IMG_001-3. You may be able to control the order of the bracketed sequence, but not assign those custom suffixes in-camera.
