I used Rodinal with Tri-X exclusively for over 15 years thanks to a formula from Bill Pierce. My negatives were clean and sharp, and my prints have a long tonal scale with excellent acuteness. To help with the grain, use this formula. For two reels of film, normal contrast, dilute 1:75 and add approx. 50 grams of sodium sulfite. Develop for 10 1/2 minutes @ 68 degrees. To increase contrast change dilution to 1:50. To lower contrast dilute 1:85.(posted 8608 days ago)
