[QUOTE="Fred Kingston, post: 690695, member: 10742"] You may have answered your own question. First some basics. Nikon apertures are wide open. When you fire the shutter, it closes down to its set position and the mirror swings up out of the way. Those are physical mechanical motions. When you switch ON live view, it closes the aperture to whatever position the camera is set for and lifts the mirror. <--again, that's a mechanical motion. If you subsequently change the aperture setting, the aperture doesn't physically move again until the shutter assembly fires... hence, even though you're closing/opening the aperture setting you're NOT seeing any change. During all this, if you change the Exposure Compensation, there is a change because what you're doing there is changing the bias of the sensor and the linked brightness of the LCD display. That's NOT a physical mechanical function so you actually SEE a difference... Hope this helps... [/QUOTE]
