Thanks for the comments Wayne. I usually do more complex stacking with Zerene
Stacker (ZS) on tiff files. More similarities than differences with Helicon
focus. The version of ZS I have strips the exif but I put I have to fuss with
exif anyway with Big Foot so I don't want to pony up the extra dosh for
Prosumer version. The stacking results are no different. Oly auto focus
bracketing usually works but oddly no auto focus bracket on Sonnie anyways. CV
lenses are MF anyway and that is easy enough inside but not with critters.
Deep stacks do better with their Pmax algorithm vs DMap in ZS but usually best
to try both and pick the best features of each. Often it is faster to clean up
halos using a Dmap with high contrast threshold than to use the individual
frames but both methods work.
When one can see the transition area, can re-stack with the larger "smoothing
radius" and use that to fix the area or just blend it in in PS. Only some pixel
peepers really notice that---you know who you are . ;-) (You would be
correct if thinking about our august listee, largest member of the cervidae
family, Alces americanus.) It is very imp't to clean up the halo artifacts
though.
It can take longer to PP the images than taking them.
I miss a few dings here and there still and usually save the .psd files as
strike hand on forehead and wonder how the problem was missed in the first
place.
