Hi,
If people are going to go to the trouble of using a tripod all the
time they might as well use large format cameras.
35mm is for hand-holding.
Ever since good old Oskar hammered a piece of old pipe into a lozenge
shape and stuck a lens on the front 35mm photographers have done ok
without tripods.
What's Really Right Stuff, and is it all really wrong, like his tripod
advice?
