FX-37 video on You tube "Testing T-Grain Film with a Sharp developer"

for those wanting to know about using FX-37 developer, I noticed this new You Tube video today, featuring Mr. "Flic Film" himself.




their is another thread on making Fx-37 from Scratch.

Crawley's FX-37 Developer for T-Max/Delta Films

Gerald Koch submitted a new resource: (there was a url link here which no longer exists) - Crawley's FX-37 Developer for T-Max/Delta Films This developer is intended for use with T-Max and Delta films, although it will produce excellent results with traditional emulsions. FX-37 is designed to...

The YouTube link doesn't show us anything about how FX37 sharpens the negatives. They need to show us a comparison between a standard film developer and the FX37 to see how the results compare.

+1.

And:
To really evaluate sharpness you have to look at the negative directly (at least with a very good 10x loupe), and not on scans (with their severe resolution and sharpness reduction) on a computer monitor (even further massive quality reduction by that).

He also made a mistake about the history of Delta 100 and T-Max 100: Kodak T-Max 100 was introduced to the market at first (in 1986), and Delta 100 came much later (in 1992; Delta 400 was introduced in 1990).

Alan,
Yes, I remember reading that part of Crawley's statement when I was using/mixing FX37. So I'm guessing people who just scan their negatives and those who only wet print might see things differently. Scanning wise, I always like a little thinner negative, but with Delta 100 and FX37 I'd have to have a little denser negative for wet printing.

I tested FX-37 extensively a couple years ago and found that although it did result in negatives that appeared sharper, it did so at the cost of degraded tonality: transition between softly contrasting areas was rendered far more harshly with an aggressive, unpleasant look. Because of this I abandoned FX-37, since I value the preservation of the impression of tactile light.

YMMV, of course. For many, I'm sure the enhanced sharpness look will be the cat's meow.
