"Bracketing question on D7100 -Confused"


Winter Garden, US
          

I am trying to take 3 shots using bracketing. My settings are: A Priority F8; Bracketing set at +3 0.3 ISO A. Now when I take the 3 shots I get: 1/50 F8 ISO 100; 1/40 F8 ISO 110 and 1/40 F8 ISO 140. I guess I was expecting to see a shot at F8 then one before this F stop and one after this F stop. However, the only thing that changed was the shutter speed and the ISO. Is this way it is suppose to work? I took the same shot with S selected (250) and these results: 250 F3.5 ISO 100; 250 F3.5 ISO 125 and 250 F3.5 ISO 160. In this case the only thing that changed was the ISO. I thought the F stop should change. Maybe I am just confused as to how bracketing works.

Your bracketing is working properly. Is 1/40 sec your low shutter speed limit in the Auto ISO menu?

In your 2nd case when using shutter priority since you're using a f3.5 lens you're as wide open as you can get so the only thing that can change is ISO.

When I bracket my shots I never use the slowest shutter speeds, the widest apertures or Auto ISO. Actually I never use Auto ISO for any of my photos.

Looks like Len is pointing you in the right direction.

For bracketing, you need to be aware of what your min and max apertures of the lens are, your min and max shutter speeds of the camera are, and how much interference any of the "auto" features (like auto-ISO) are going to give you.

In your first run you bumped up against the min shutter-speed set in your auto-ISO settings. In the second run, you bumped up against the max aperture of the lens.

The more common settings for bracketing are similar to what you had in your first run (aperture priority). You just need to temporarily turn off the auto-ISO settings.
