i often look at large old b&w prints and am amazed at the quality of image and printing that somehow with the digital age
I have a lot of those images as well. Most of the B&W prints from 1950's and earlier were shot on MF and LF film, and often contact printed. This produces images with tonal ranges that match anything today, if not exceed given the raw density range of those old papers.
However, small format is what killed MF and LF, along with deterioriating quality standards as consumers wanted convenience in the 60's and 70's rather than larger format area. To this day I still see the same bunch of college freshmen taking 'wet-lab' classes and producing the same tonally deficient, grainy, bland 35mm prints from 400 speed Tmax.
They then post those images on this forum and the film nitwits compliment them on images that 20 years ago would have got them a D- minus in Photo 101.
Also, digital didn't kill Kodachrome, but Fuji did. Kodachrome sales were in free-fall the day Fuji started making slow speed E-6 films.
Ask a fashion photog in the 90's if they preferred Kodachrome, or EPP
EPD or Velvia. Fact is, if professional and commercial shooters didn't shoot Kodachrome when film was at it's height, then a bunch amatuers aren't going to re-write history because they can't use a dSLR.
