From Kodak's table it seems that about 25% time increase is needed when you move from 1+1 to 1+2, and a 50% increase when you move from 1+1 to 1+3. However, there is a rather wide variance from film to film. (The change from 1+0 to 1+1 also seems to involve a 25% time increase, again with variances.) My 1+1 times for an e.i. of 3200 are 19 mins at 68°/20° or 16 mins at 22°Celsius (Celsius was a fellow countryman of your wife!) which I think is 71.5°F (for funny) I also had good results with1+0 for 10 mins at 68° with and e.i. of 1600. If I add 25% for the extra dilution and 15% for the 1600 to 3200 move, I would get less than 15 minutes and not 19, which just goes to show that the above percentages are just starting points. Hope this helps more than it confuses. - -- christer almqvist eichenstrasse 57, d-20255 hamburg, fon +49-40-407111 fax +49-40-4908440 14 rue de la hauteur, f-50590 regnéville-sur-mer, fon+fax +33-233 45 35 58
