Good tips above - I didn't realize about the shutter speed vs. f stop, good to know. Thanks.
Usually shoot the LCC right after the shot, so it has the same shifts as the shot. Also, easier to find in C1 when processing - just look to the end of a particular sequence, find the LCC, and adjust.
There are some cases (60mm, with center filter), where the LCC isn't critical, and if in a hurry, don't shoot one. If there is a critical issue (like sky shift), might throw the image into BW. Also, one can (if well organized!) make a set of LCCs to have on stock - I typically shift in 5mm increments, and so one could (in theory) take an LCC from a set pile of pre-shot ones, and apply it. I'm not so disciplined, and haven't been able to do this, but sometimes in a pinch one can even (if you can remember the shift pattern) do one after the fact...at least get some improvement.
As to the ground glass and composition - there seem to be two ways of working: one is very deliberate, and set up and compose carefully. That's best with a stitching back, maybe live view (which my Credo 60 doesn't have). The other is a bit more "run and gun" and with a combination of a slightly looser approach to framing, and chimping, manages just fine. Both are used. Depends on one's preferences. I like to move around outside in an area for shooting, say about a 100 yard radius for an hour or two. Keeping the back directly on the camera, on the tripod and slung over the shoulder, works well for that. A stitching back works well for a athoughtful set of architectural shots in a discrete area.
