Just developed a roll of K-64. I'm impressed with how they look. Just pulled the roll out of the fix, and wowwy zowwy, gorgious negatives. I prewashed with TSP, took three wash and rinse cycles before the water came out clear, no scrubbing needed. Fifteen minutes in D-76 stock followed by thirty seconds in acid stop followed with two clear water rinses then fixed(TF-4) for five minutes. Have them hanging to dry at this very moment, can't wait to print them.
