DOF ([[Depth-of-field]]) bracketing comprises taking a series of pictures in stepped apertures ([[f-stop]]s), while maintaining the exposure, either by counter-shifting the [[shutter speed]] or, with digital cameras, adapting the [[ISO speed]] accordingly. In the first case, it will also change the amount of motion blur in the picture. In the second case, it may visibly affect image noise and contrast.

Combining DOF bracketing with [[multiple exposure]], the so-called ''STF effect'' (for ''Smooth Trans Focus'') can be achieved as implemented in the [[Minolta Maxxum 7]]'s automated [[STF function]]. This closely resembles the [[Bokeh]]-pleasing optical effect of the [[apodization]] filter in the [[Minolta STF 135mm f/2.8 T4.5|Minolta/Sony STF 135&nbsp;mm f/2.8 [T4.5]]]'s special-purpose lens.
