Lara and I thoroughly enjoyed the day, so thanks to Leon, Paul M and Phil.
I also picked up some useful hints and tips from Leon, Paul and Phil. The one thing that really dawned on me, though, is that more than any other format I've used so far, getting proficient at LF will take a lot of time and practice. So, I'm going to be setting up the rig in the kitchen and trying out all the camera movements so that I'm a bit more familiar with them "in the field".
Taking a meter reading first (only for the light to have changed completely at the point when you want to hit the "go" button), not taking out the dark slide before hitting the shutter, taking it out when the shutter is wide open and forgetting to mark which film holders / side of film holders have been exposed are but a few of the comedy moments in my, so far, brief foray into LF photography.
Being really well organised and getting one's own routine is critical. Here's a scan of a Polaroid Type 52 (expired 2006) shot I took yesterday. Okay, it's not the Mona Lisa but I was pleased to see a result on the day.
