In practical terms, how does one get results shooting at f/22 @ 1/1000? I was reading that this was the MO of one of my favorite photographers, Mark Cohen. He used a 28mm lens for his classic work and was known for getting dangerously close to his subjects. I believe he used a Leica (there’s at least one video on YouTube, but it’s in German). f/22 obviously blows open your DOF to the point where you don’t have to think much about focusing – but does this hold when you’re inches from your subject?
Honestly, coming from digital, I was surprised to hear that one could get any sort of usable results allowing so little light to reach the film. I wonder what sort of film Cohen used and how he developed it. Cohen shot black and white (primarily) but has done a lot of work in color also. What 35mm films are available today that can be pushed to give results using such extreme settings? (Or maybe they're not so extreme for film shooters...)
