Exposure Compensation - question

[Infidel]

Well in A, it should change the shutter speed and in S, it should change the aperture. Doesn't it work that way?

Yes, I have used exposure compensation to shoot HDR sequences in aperture priority mode. It changed shutter speed; ISO and aperture were left constant. BTW, I shoot with a D40, so no auto-exposure bracketing.

Good point, as just last night i looked at a student image from an assignment and it was seriously overexposed and when I looked at the medata it was 3.7 over. Her husband had been messing around with dials.

There is no way to compare the numbers to another students image.

I am just passing on infor given to me from Nikon , I called because I didn't know. Perhaps this is a good time to run a simple test for myself.

The weather is awful, but is should clear up in a few days, and i will get back to this thread with the test results. This is one of those things that I just do in my head in manual mode and don't think about it.

I was thinking about this on my way to class tonight.

EC and AEB are not the same thing. This is what the D700 manual says "In exposure mode M, only the exposure information shown in the electonic exposure displayed is affected; shutter speed and aperture do not change."

In AEB mode with aperture priority the shutter will change and with shutter priority mode the aperture changes. I can use up to 9 images at 1/3 steps, and in manual mode one can go into the menu and tell the chip which value is constant so the other changes.

I try it when the camera is attempting to meter the scene but the histograms show clipping of data.

ha ha exactly, but that went over their head mate.
