A 12 x 16 image from Delta 400 or 100 ( or Kodak T Max films )
is well within the reach of a competent photographer. It isn't THAT hard, and lots of folks can do it.
Can you tell the difference between prints made in MF and 35, side by side ? Well, sure. Does that make the 35mm image inferior ? Of course not. Does that make MF superior ? No.
Here's the unspoken reality: you can make superb images from 35 in conditions that are impossible to make ANY image from MF.
When and where you make pictures is the real question.
Sunny days on a tripod, MF.
Handheld at twilight, 35mm.
In between, that's up to you.
Thanks for reminding me that it's all a compromise and MF is as much a compromise as 35mm.
Cheers
