I want to try out azo printing using the suggestions Michael Smith makes in his various articles about it, one question I have is about the hieght between the bulb and the paper- how far should the distance be? He does not state this in the articles-
"I recommend using an R–40 300-watt light bulb, one with the silvered part on the neck of the bulb. The average exposure should be between 10 and 20 seconds, but fine prints can be made with exposures as short as 3 seconds and as long as 3 minutes"
Thanks
