I got close to 250 sheets of Kodak Polycontrast III RC 8x10 photographic paper ( or i'd say reasonably 90% left from what the student used ), about 15 sheets of ilford multigrade IV Fiber Glossy 8x10. For one I dont know if the paper is still good (you know like open the box. "oopsie" close it up by the previous student), and I'm thinking bout doing some contact prints from some 6x9 negatives. Thing is I don't want to go out and buy a bottle of paper developer especially if I dont know which I want to get. So I'm wondering. Can I just use some HC-110 developer as a compromise. I also got an old orange bottle of Agfa Nuetol universal paper developer concentrate that is said to be able to do 100 8x10 prints, however according to the data on the box the moment I mix the 1 Litre stock, I have 4 weeks before it goes bad and I don't want to be cracking it open just to do a couple then have it go back from the time. Thoughts?
