To give an example of the gulf being developed in photographic understanding by this rampant commercialism: - Some time ago, I was demonstrating a pinhole camera to a group of students and one of them said “that will never work Clive, it’s got no batteries”. I was lost for words. Other comments I get are “I found an old camera; do you think it will work”? In other words if it isn’t the latest thing, it’s inferior. It annoys me that camera functions are given more emphasis than seeing.
