Barnbaum now uses the following dilutions for TriX 320 rated at asa 160.
First he makes a stock solution of 1:3. Then he takes that and further cuts it to 1:12.5.
If you were just going from the concentrate to the final dilution what would it be? Would it be 1:37.5? I just have a mental block when it comes to ratios and dilutions etc. Duh!!
