Whatever
Another glass plate shot - I still have a long way to go before I get consistent results that I'm happy with.

It seems like you have made great strides already in showing what was possible in photography in the 1920s and what remains possible today using the same resources. You have inspired me to get back to shooting my own compact plate cameras, but I think I won't feel I have completed my own journey with them until I have produced a few dry plate images.
I'm enjoying the photos, even if some seem a little bit back-focused. Do you have any way of checking to see whether the camera's distance scale is accurate in those middle ranges which are causing you grief?
...and just how large did they print their pictures in those days?
I figured out (I think!) what the focus issue was this past weekend -- I was using a Leitz 'FOKOS' rangefinder that was giving me erroneous readings (too far!). I'm going to have Frank look at it as well as the camera anyways just to make sure that everything is lining up.
Make sure you don't have the "OUTTA" accessory on your "FOKOS", otherwise it will be...🙂
OOPS! Sorry about that, Vince. Now I'll have to check the other one to see if it's got an OUTTA also. Probably check it against a digital camera to see where the focal point falls.
