Bracketing Sequence
This setting determines the sequence of exposures when using Auto Exposure
Bracketing (AEB) or White Balance Bracketing. (Remember that the 5D Mk III can
bracket either 2, 3, 5, or 7 shots, not just the traditional 3 shots - number to be set with
the next menu item). The bracketing sequence setting depends how you like to order
your bracketing, and this may be important to you if you do a lot of HDR work. Setting
“0 - +” means the “correct” exposure is taken first, then the darker exposure(s) (under
exposed), then the lighter exposure(s) (over exposed), with “correct” meaning what the
camera thinks is the proper exposure. Setting “- 0 +” means the order is darker, normal,
lighter. Setting “+ 0 -” means the order is over exposed (lighter), normal, under exposed
(darker). I prefer setting “0 - +” but an HDR shooter and their software may prefer
setting “- 0 +”. This also affects the bracketing sequence for white balance (WB)
bracketing so determine what sequence you want if you make use of WB bracketing.
recommend: the first setting for general use, the second setting for HDR shooters.
Number of Bracketed Shots
This is to set the number of shots that are taken in an Auto Exposure Bracketing (AEB)
sequence or a White Balance (WB) bracketing sequence. The number you choose is
obviously the number of shots that will be taken: 3, 2, 5, or 7. General bracketing is
typically 3 shots, but those shooting for HDR work will want to take advantage of 5 or 7
shots. recommend: varies by user
Safety Shift
This option, Safety Shift, allows your camera to change an exposure setting without
your expressed permission when it is vital to getting the shot. This is a good thing in
certain situations, such as when shooting at a concert and the lighting and lighting-
levels are changing erratically, or when shooting in very dim light without flash, and
proper exposure may not occur based on your current aperture or shutter speed
settings. It only functions in Tv, Av, or P Shooting Modes, based on the following
options:
Tv/Av: Shutter Speed/ Aperture will automatically change the mode’s setting in
order to obtain the proper exposure, meaning that in Shutter Priority (Tv) mode it
will change the shutter speed setting, and in Aperture Priority (Av) mode it will
change the aperture setting. So consider which variable you would want
changed, and which one you wish to “hold” when deciding on a shooting mode.
You may wish to work in the other shooting mode than you usually do so that you
can hold your desired (aperture or shutter speed) setting.
ISO: ISO Speed will work in Av, Tv, and P modes. In order to obtain the proper
exposure, the camera will change the ISO speed. This may be the more
desirable setting, since the low light capability of the 5D Mk III is exceptional
even at very high ISO settings, and that way you can allow the camera to adjust
