Tilt (swing) is a powerful tool long enjoyed by view camera users. While it does not and cannot help for every situation, those scenarios in which it applies can seemingly violate the normal rules for depth of field.
In Making Sharp Images, I show just how effective the use of a tilt lens can be (usually the lens is a tilt/shift, offering both functions).
This article should be of interest to anyone using Canon or Nikon or other brand tilt/shift lenses for tabletop/product photography and/or landscape, etc.
A full aperture series with and without tilt from f/2.8 through f/32 is shown in both HD and UltraHD sizes along with crops. So one can compare both across the series as well as comparing (for example) f/5.6 with and without tilt for the entire frame and also at left/right/center large actual pixels crops.
