combining automatic iso and aperture priority on the nikon d700.

now that i use a digital slr that is rather exceptional in the way that it is capable of producing high image quality at high iso:s, i find myself using the following little trick more often than not. i'm sure most of you are aware of it, but still, here goes.

the aim of the trick is to let you control (fix) the slowest shutter speed AND the aperture, while the camera automatically varies the iso setting to fit the scene at hand.

first off, set the camera to use automatic iso. on the d700, you can set the maximal iso, as well as the slowest shutter speed to use. for instance, if you're using a 50 mm prime, you can set the slowest time to be 1/60 of a second. depending on how you intend to use the images, you can allow the camera to use iso:s up to, say, 3200 or even 6400.

the second thing to do is to go into aperture priority. once that's done, you're set to go. the camera will now vary the iso between the base iso (typically 200) and the maximally allowed iso (for instance 3200), while taking the aperture you've chosen as well as the slowest shutter speed into consideration.

try it, you'll like it.
