What is the "AE" Lock Feature used for?Many Nikon digital cameras have an "AE" or Auto Exposure lock feature.When pressed, the AE Lock button locks in the auto exposure and white balance so that subsequent photos have the same exposure and balance. This can be useful when taking panorama photos so that consistent exposure is achieved across all images, or when you wish to expose for the background and then recompose and shoot a photo.
