I bought some old films that are likely to be fogged, or at least there is a risk of it, so I bought Photography Formulas potassium bromide.
It comes in crystals, and no instructions.
How much of it would you use and would you mix it with the developer - such as Rodinal 09 or Rodinal Special One shot.
I could weigh up the crystals letīs say 2 grams or 5 grams - how much water would you recommend - which dilution?
KBr is a known anti fogging agent in edev formulaeas it buffers development,adding it toexisting formulae is likely to upset the fine balanceof ingredients and could impede development beyond your wishes.if you insist to try,I'd start with no more than 0.5g/land increase by the same amount until you get your desired result.good luck.
