I want to learn a decent workflow for doing focus stacking together with
panorama assembly ("together" meaning NOT one before the other). There are
a bunch of different aspects of this for which I could use advice.
My camera doesn't do focus stacking. With a camera that does focus
stacking, the different focusses of each position of the panorama would be
very easy to align well, so it would make more sense in post to merge each
focus stack before assembling the pano. Instead, I will be taking all the
shots for one focus setting, then changing focus and taking them all again,
which simplistically sounds like I should assemble a pano for each focus
setting before merging by focus setting. But that seems to not work right
either.
I think the heart of the solution must involve the save-mask and load-mask
operations in enfuse. I haven't yet experimented with those to figure out
proper use. I want to have enfuse compute some contrast based weighting
and save that. Then I want to use other tools to examine that weighting
and modify it. Then I want to have enfuse use those weights rather than
contrast etc. Maybe I want also to get some kind of masks out of enblend
as well to mix in.
I don't know whether save and load masks actually work that way, nor what
other settings to use. I don't know what tool to use to look at a grey
scale masks together with the photo (make one semi-transparent to look at
the other through it or what?) I have Corel software that came with my
camera for such things, but don't know how to use it, and/or I'll download
whatever freeware is suggested for viewing/editing the masks.
I'm a software engineer. For the alignment part of this workflow, there
are a few small code changes I want to make to Hugin. The code itself was
easy for me to understand. But the Windows build process is beyond
cryptic. The build instructions I found are full of necessary links all of
which are broken (go to 404 page missing). Once I start actually
understanding enfuse/enblend I expect I'll want to change those as well.
Build suggestions appreciated.
I'm hoping/expecting to be able to construct masks that have 100% in
certain areas (not isolated pixels) of high contrast for an individual
photo (with 100% in any one forcing zero in overlapping part of each other
photo). Then have mixed weights (not 100% / 0% selection) in transitions
between the selected part of one and the selected part of another as well
is in the shared low contrast sections of all photos (I'm expecting to
stack two or three photos with low depth of focus so objects further in the
background intentionally remain blurred).
Sorry this is so long and implies questions for multiple different kinds of
expert. Thankyou for taking the time to read it and for any suggestions on
parts of it.
