Locking Flash Exposure
In automatic TTL mode, you can lock the flash output level that is optimal for specific elements of your scene
by using the flash exposure lock (FE Lock) on your camera. To lock flash exposure, follow these steps:
1. Set your camera to any Program or Manual mode.
2. Position the element of your scene that you want to be correctly exposed in the center of your viewfinder.
3. Press the FE Lock button on your camera. The flash will fire a test shot and lock its output level, and an
asterisk (*) will appear next to the flash icon in the viewfinder.
4. Reframe your image as desired and take the picture.
For more information about the FE Lock feature, consult your camera’s instruction manual.
