Found it: Farmers Reducer: Mixture of Hypo and Potassium ferricyanide 100g Sodium Thiosulphate 50g Potassium ferricyanide Water Make up to 500 ml Do not use "acid fixer" or any usual commercial fixer. Use of acid will release prussic acid which is extremely poisonous - if you get a lungful (it is a gas) it will kill you in 30 sec. (Used by Saddam Husain in his gas attack on the Serbs) Make up and use immediately. Dispose of safely. Plenty of water flush down sink - if only a little. Take it to specialist toxic waste disposal unit for larger quantities. Dip negatives in this solution held at 20 C and agitate. Watch until density gets to desired or correct value (by eye) Only works on silver based material. Wash film as usual afterwards.

This Xmas, after my wife and I had lunch (and a few glasses of wine) I ran out of color film, so I stuck a roll of Ilford HP5 in my camera and starting shooting away. Due to the wine effects some of my shots came over exposed... 2 to 3 EVs (guesstimate) and they look almost as white squares in the contact print. My question is how to print them. high or low contrast paper? Energetic or mild developer? Any ideas? Also I used the TTL setting in my Metz 300 series flash with a SCA 346/2 adapter (Nikon AF). I bought the adapter used so I don;t have a manual for it and I assume that all it does is convey the info between camera and flash. Does anyone have a manual SCA 346/2 that could copy for me? Thanks and happy holidays!!!
