Stacking using Zerene Stacker.
I’ve come across many a subject that simply could not be photographed in the way I conceived it: fully crisp where I wanted it so:. There was no way to capture it in a single frame because key areas would blur-out from lack of depth of field and diffraction. This applies particularly to subject matter at close range and/or extended near-far compositions.
These examples use focus stacking (Zerene Stacker) to deliver far more detail than is otherwise possible, even at f/11. Focus stacking is the only method by which adequate depth of field can be obtained in such scenes (while retaining strong contrast), f/11 being inadequate and f/16 far too damaging to contrast at all levels, from diffraction.
The Zeiss Milvus 25mm f/1.4 is ideally suited to focus stacking, with outstanding control of color aberrations, an f/1.4 aperture to nail the focus where desired for precision stacking, and a low level of breathing (change in focal length with focusing). Its 24mm focal length at f/9 - f/11 means that many scenes require only two frames for stacking.
Includes images up to Nikon D850 45-megapixel resolution. Many have both color and black and white renditions. These examples took about an hour each to prepare.
