Very interesting Tony, glad it went well.
Whilst I have scanned the horizon, sometimes 360 degrees looking for a picture or whatever with 35mm and medium format, I cannot say I have tried it with LF. I see the logic and I may try it, but I'm not so sure it's for me, interesting!
I was taught printing with a metronome, never liked it, I was always losing count when burning in.
In what area of spotting were they either different or unusual, to what you know or do?
