EOS Focus-bracketing & layered/stacked images to increase DOF

[WJM]

After studying the fascinating concept of layered/stacked images, to
achieve an infinite large DOF, and vaguely recalling that *some*
later DSLR's (or even compacts?) have focus-bracketing....

....I was wondering how long it would take before this stacking-
software might become part of the OEM image-software, external or
internal, in combination with such focus-bracketing.


Some of these stacking programs & fascinating samples:

Btw, the focus-bracketing could even have a manual mode, for non-AF
lenses, like dedicated microscope stuff....if external image-software
can detect the exact sharp area within a layer, then internal
software should be able to give a signal when you run out of the
singular DOF (overlapping DOF is recommended).

(wondering how well this would work with scanned analog images,
despite the recommendation to use only straight-digital....if only to
test this with 6x12cm panorama frames....turning a Noblex with focus-
option or even macro-diopters into a much more interesting device)

Hi Willem-Jan,

A friend with one of Canon's 65mm macro lenses (usable in the 1:1 to 5:1
range), used it on my EOS 10D and took something like 5 or 6 focus stacked
frames for each of a stereo pair of some quite small items in the extreme
close-up region.  Both sets were then put through.Heliconfocus, and printed
as a stereo pair.  The result on some of his samples were quite stunning
stereo images of items such as lichen.
