Flash Power Lock
When the back ground of the main subject is too bright, the camera’s exposure
reading system adjusts the flash light intensity for such back ground condition and
it results in the main subject being underexposed. Or in case the main subject is
not placed in the center of the viewfinder, the flash picture may result in the aimed
targeted subject being under or over exposed. You can lock the correct flash
exposure for the targeted subject in such a condition. This flash exposure pre-set
remains locked in, even if you change the aperture or zoom the lens in and out.
This mode can only be set on the camera.
