Exposure Compensation - Pentax IQZoom Operating Manual

EXPOSURE COMPENSATION
If you take a prcture of a person with the sunshine
behind, or the bright sky or snow scene in the
background, the face tends to be underexposed,
looking so dark. To avoid this, release the shutter
while keeping the exposure-compensation button 13
depressed. The face will then be properly exposed
and look bright.
When shooting in a poor lighting condition, it is
more effective to use flash (as daylight-sync flash as
described on page 18) than to use the exposure-
compensation technique.
