I've talked a lot about exposure compensation. So let's look at how this important function works. First of all, is useful to know. It only works in the automatic or semi auto exposure modes. It doesn't work in manual mode. On some cameras, compensation is set with a button and one of the command dials, while in other cameras it might be a dedicated dial. Now, when set to zero, no adjustment is made to the cameras. Exposure assessment. If you want to add, like to increase the meted exposure, you're just a compensation value to one of the plus numbers. For example, plus one toe. Add one stop of light platitude at two stops and so forth. Likewise, setting one of the minus values will reduce the exposure because you're telling the camera to take light away. Minus one reduces exposure by one stop minus two by two stops. Etcetera. Now average a priority, the camera adds and subtracts light by adjusting the shutter speed. Because you're controlling lens aperture in shutter priority, the came...
ra adds and subtracts light. By adjusting the lens aperture in full auto or program mode, the camera may use a combination of shutter speed lens aperture and even eso to make the exposure adjustment. And that's it. 01 more thing. A really important point to remember is if you set exposure compensation, remember to set it back to zero after the shot. Otherwise, every subsequent image will be affected. It may sound obvious, but it's easy to forget, especially if it's your last shot and you don't pick up your camera for a while. Trust me, I've done it.
