I developed a roll of Scala (asa200) using Rodinal 1+20 for 8 minutes at 18c, and was happy with the results. I have another roll that I pushed 2 stops to asa 800. I'm thinking the developing time should now be 18 minutes under the same conditions, but math was never my strength. Can someone either confirm my calculations or set me straight? Cheers,
John
