I was lazy and googled to see if any of the formulas for these developers were online.
I found a few references to D8 - Kodak may still carry this developer All of these developers are high energy developers that would create negatives of extreme contrast if developed at room temperature. At low temperatures they behave more like a standard developer. I believe the high pH balances the loss of activity at low temperatures. Another developer to try at low temperatures is D-19 its a high contrast developer. It produces a moderately high contrast - it may produce normal contrast negatives for film processed betweem freezing and room temperature. Only way to find out is to experiment. If you mix any of the developers below be very careful with Sodium Hydroxide Gord From http://rmp.opusis.com/formulae/silvergel/developers/kodak_d8.html Kodak D-8 Developer Water, about 32 Celsius (90 degrees F.) 750 ml Sodium Sulfite, desiccated 90.0 g Hydroquinone 45.0 g Sodium Hydroxide (Caustic Soda) 37.5 g Potassium Bromide 30.0 g Water to make 1.0 liter Dissolve chemicals in the order given. Stir the solution thoroughly before use. For use, take 2 parts of stock solution and 1 part of water. Develop about 2 minutes in a tray at 20 Celsius (68 degrees F.). For general use, a developer which is slightly less alkaline and gives almost as much density can be obtained by using 28 g per liter instead of the quantity given in this formula. From: http://www.fotoinfo.com/info/technicalinfo/undexp.html Kodak D-82 For low temp developing and underexposed negs. Water 52 degrees centigrade 750 cc Methyl Alcohol (Wood) 48 cc Metol 14 grams Sodium Sulfite, Anhydrous 52.5 grams Hydroquinone 14 grams Sodium Hydroxide 8.8 grams Potassium Bromide 8.8 grams Cold Water to make 1 liter Dissolve the sodium hydroxide in a small amount cold water. Then pour this into the mixture, after the hydroquinone with rapid agitation. If you pour sodium hydroxide into hot water, an explosive reaction can occur which can cause burning. Tank 6min/20 degrees centigrade. 5min tray.
