Bracketing in continuous mode < Extra Photo Operations < Main Menu
Bracketing is the practice of making several exposures of a scene, with each
exposure differing from the next by predetermined steps in exposure or focus
settings. Bracketing is used to easily capture a range of exposures so that the
best exposure can be selected at a later time. Bracketing is also used to create
a series of exposures which will be combined using methods such as HDR
processing.
The bracketing features are enabled when the camera drive mode
is set to continuous, and custom timer with some models.
!
! ! Usage Tip: If you wish to fire off individual frames and still have
! ! bracketing for each one, after the first shot lightly let-up on the
! ! shutter button to a half- press position. The next full-press will
! ! give you another bracketed shot. This process may be repeated
! ! for as many bracketing steps as you need. Giving you finer
! ! control over the number of bracketed exposures you may require.
