Thanks, Martin. And thanks for reminding me about this thread. I need to do something similar again. Photography must be about something more than cameras, analogue v. digital, film, processes, editing, etc, etc. It's when I concentrate on those things that I start to drift, and ultimately lose interest in photography. Philosophical speculation, on the other hand, can often sound like Pseuds Corner. As ever, it's all about balance.
It's funny how we upload images here, as if they are the end result. But they never are.
