I was sent Henry Soper’s remaining original material a while back but I’ve never seen any of Harold’s. It’s quite fascinating to see the differences between the film results and current video systems.
PS, Had to check. Yes, one of Harold’s photographs is in Neil Bones’ book. I knew I had seen one recently. Do you know what happened to his originals?
I have scanned the ones from Henry, ultimately I’ll send them to the BAA for archiving.
