Ae Lock; Ae Bracketing - Olympus E-620 Instruction Manual

AE lock

The metered exposure value can be locked with the AEL/AFL button (AE lock). Use AE lock
when you want a different exposure setting from the one that would normally apply under the
current shooting conditions.
Normally, pressing the shutter button halfway locks both AF (auto focus) and AE (automatic
exposure), but you can lock the exposure alone by pressing the AEL/AFL button.
Press the AEL/AFL button at the position where you
wish to lock the metering values and the exposure will
be locked. The exposure is locked while the AEL/AFL
button is pressed. Now press the shutter button.

AE bracketing

The camera automatically shoots a number of pictures at different exposure values for each
frame. Even in conditions where correct exposure is difficult to obtain (such as a backlit
subject or a scene at dusk), you can pick the picture you prefer from a selected number of
frames with a variety of different exposure settings (exposure and compensation values). The
pictures are taken in the following order: Picture with optimum exposure, picture adjusted in –
direction, and picture adjusted in + direction.
e.g.) When BKT is set to [3F 1.0EV]
