Bracketing In photography, bracketing is the general technique of taking several shots of the same subject using different camera settings.
ISO bracketing ISO bracketing is a form of simulated exposure bracketing in which aperture and shutter speed (thus depth of field and motion blur) remain constant.
DOF bracketing DOF (Depth of field) is taking a series of pictures in stepped apertures (F-stops), while maintaining the exposure by adapting the ISO and shutter speed accordingly.
Shutter Speed bracketing Bracketing with the shutter speed is another form of exposure bracketing, but with it’s own unique, less drastic effect.
