Locking The Exposure Setting (Ae Lock) - Canon Powershot SD890 IS DIGITAL ELPH User Manual

When shooting with the focus lock or AF lock using the LCD
monitor, setting [AF Frame] to [Center] (p. 93) makes
shooting easier since the camera focuses using the center
AF frame only.
The AF lock is convenient because you can let go of the
shutter button to compose the image. Moreover, the AF lock
is still effective after the picture is taken, allowing you to
capture a second image with the same focus.
AF frames do not display in movie mode.
Try to shoot as close to the glass as possible to reduce the
chances of light reflecting back off the glass when you shoot
a subject through glass.

Locking the Exposure Setting (AE Lock)
