Nikon camera control software for HDR?

I need a way to program up to twenty ISO/aperture/shutter speed combination into the camera prior to remotely triggering it to take a series of shots that will later be combined into an HDR image. Any ideas? The camera is a Nikon D7000.

I don't know if the D7000 has a sequential exposure feature. You will have to check the user manual.

It does have a bracketing mode that can do that part of the HDR requirement for you. To modify ISO between shots you will have to use the auto ISO feature too.

My old D300 has both features although I have never used either of them.

Curious: How are you planning on using all three of these features simultaneously? For what purpose?

Altering the ISO and aperture between shots will change more than just the exposure - ISO changes will affect the noise in the image and aperture changes will affect the depth of field.

I suggest you just take a series of 20 shots changing only the shutter speed to alter exposure (that's how HDR's are done) and then combine.
