Alex,

I worked up my development times by tailoring the negatives to the exposure scale of Azo paper. I found that grade two Azo will handle a density range of 1.65 and grade three Azo will handle a density range of 1.35.

I determined this by testing the paper with a reflection densitometer and by testing the negatives with a transmission densitometer.

The times that I have stated above will provide those negative densities if the same temperature, dilution, and agitation procedure are adhered to.

My dilution is 1-1-150 and the temperature is 70 degrees.

Good luck
