I use the straight syrup out of the bottle. 12 mL in 600 mL water, one-shot developer. Inversion that takes 2 sec. to invert and return to upright. Invert 15 times in the first 30 sec. and 5 inversions in 10 sec. at each minute, on minutes one through eight. Pour out developer at 9 minutes development time for TMY-2. I use Indicator Stop then I use Eco Pro fixer for 7 minutes with the same inversions as developing. Works well for what I want. This is for ISO 400.
