exposures are automatically taken during auto Bracketing. Right: Safety Shift options, to
determine which exposure settings the camera will automatically change, if necessary,
in order to obtain the correct exposure.
I-6: Safety Shift
The Safety Shift feature allows your camera to change an exposure setting without your
expressed permission when it is vital to getting the shot (see Figure 125 - right). 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:
0: Disable - Safety Shift not used.
1: Shutter Speed/ Aperture will automatically change the current Shooting
Mode's setting in order to obtain the proper exposure, meaning that in Shutter-
Priority (Tv) mode it will change the shutter speed setting (which you are
selecting when using Tv mode), and in Aperture-Priority (Av) mode it will change
the aperture setting (which you choose when working in Av mode). So when
using this option, realize that if the camera cannot obtain the proper exposure by
changing the "other" exposure setting, it will change the exposure setting that you
set. For example, if you are working in Shutter-Priority Tv Mode and have set the
shutter speed at 1/1000 in order to freeze the subject, the camera will normally
adjust the aperture setting in order to obtain the proper exposure. If the camera
reaches the limit of the available aperture settings (the aperture is as wide open
or as closed as it can be) and the proper exposure still cannot be obtained, the
camera will then change the shutter speed that you set so that the proper
exposure can be captured.
2: 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 80D is very good even at
high ISO settings, and that way you can allow the camera to adjust the ISO while
