Tri-X really dominated a picture in 35mm the grain was so prominent.
I actually got interested in photography because of tri-x grain.
The art department at my college contacted the chemistry department for help in minimizing grain while pushing tri-x 4-5 stops.
The chemistry department sent me- probably thought they were sending Mr. Bean
I had never seen a darkroom before, had no idea that a stop bath was different than a stop of light- I knew nothing about photography. I did know chemistry. This was 1971-72,
Worked with some chemist contacts at Kodak labs and over about a year actually got the grain under some control- it was only the size of marbles instead of basketballs. I remember it was a 2 developer process with different agents and different temperatures, but otherwise don't remember the details.
Then I fell in love with darkroom printing- and here I still am some 50yrs later.
