nikon hdr control software?
I need a way to program up to twenty ISO / aperture combination shutter speed in the chamber before activated remotely take a series of shots that would later be combined into one HDR image. Any ideas? The camera is a nikon d7000.
Alteration ISO and aperture between shots will change more than the exposure – the changes affect ISO noise in the opening and changes affect the depth image field. I suggest you just take a series of 20 shots changing only the shutter speed to change exposure (which is what HDR is done) and then combined.
