Focus breathing panorama hell
I spent a couple of days around Easter taking multi row panoramas of local blubell woods in the UK.
I used a GFX 100 and a GF110mm mounted on a gimbal head and nodal rail to get rid of any parallax issues.
My problem is the following: the depth of field on the GFX100 is incredibly shallow, even at around f/9 f/10 if the foreground is remotely close.
To get front to back sharpness, I had to focus stack every "tile" of the panorama.
Whilst it wasn't a big deal at the shooting stage (the GFX has an automated function), I had not planned for the 5+ hours I spent in photoshop painfully masking away areas that the automotic focus stacking blending had completely messed up because of focus breathing.
My question is: do you use photoshop for your focus stacking purposes or have you tried any other solution which does a much better job at picking the right sharp parts of every frame during the blending phase?
Thank you for your help!

I'm amazed you need to "tile" with the huge files from that lovely equipment! I don't stack panos often, mainly because of that hassle but I usually find PS is pretty reliable when I do. The important thing to remember is to load the layers and then always hit auto align before blending them. So for a pano, stitch each set, save each focussed set as a file. Then stack the stitched panos using auto align then auto blend.

I think some software can first correct for focus breathing...I've tried align_image_stack but it's a command line program. But it does correct for focus breathing from my macro lens before I actually stack. It's actually not too hard to use, and the -m flag corrects for slightly different magnifications. That could work.
