I've finally decided to try some Azo that I've had for about 8 or 9 years.
I've hit a problem! Michael A. Smith states in his writings that he exposes his Azo using a 300 watt light bulb and gives the paper between 10 & 20 seconds exposure. I've had a try this afternoon using a 75 watt enlarger bulb about 2 feet above the paper, with no other diffusion, and I'm getting an exposure time of 6 seconds. This is just too fast for me, I need time to decide about dodging and burning.
I've mixed a paper developer that was recommended for contact printing papers. The formula for 1 litre is :-
2.2 grams of Metol
50 grames of Sodium Sulfite
11 grams of Hydroquinone
78 grams of Sodium Carbonate
5.5 grams of Potassium Bromide
Is my problem the developer or should I just wire in a dimmer switch and live with that. I have Amidol but did not have time to devote a whole day to contact printing.Any advice would be appreciated.
Pete.
