Kodak HC-110 is a semi-compensating, fast working type developer.
Most populair are the dilutions B (1+31) and H (1+63). How more diluted how sharper and more semi-compensating the developer is going to work. But the grain will be bigger in a higher dilution.
1 ltr. concentrate which is pretty viceuse (based on Glycol) and with a long storage period.
A 5ml syringe is recommended for making a dilution directly from the concentrate.
5ml plastic syringe: See developing tanks. Temporary delivery problems.
