Auto exposure lock can be useful on bright days.
The Nikon D80 is a mid-level digital single lens reflex (DSLR) camera. It offers the benefits of digital photography, such as instant image review, and advanced features like interchangeable lenses. The camera's automatic mode is designed to make shooting photos easy, yet can be too automatic sometimes. To prevent the camera from resetting the exposure as you recompose your image, use the auto exposure lock feature. This will keep the camera's settings the same as you aim the lens at different subjects.
Instructions
1. Rotate the shooting dial on top of the camera to either the P, S or A mode.
2. Aim the camera at the subject. Press the shutter button halfway to gain focus and set the exposure.
3. While still holding the shutter button, press the AE-L/AF-L button to lock the exposure. An "AE-L" icon will appear in the viewfinder while the lock is active.
4. Continue holding the AE-L/AF-L button and press the shutter button fully to take the photo.
