I recently found and bought an enlarger (colour head) on ebay. Which happened to also come with a reasonable selecion of trays, papers (B&W), tongs, timer, dryer, bits n bobs and the guys old chemicals (about 1500ml mixed plus the original unused undiluted bottles). I put it all together in a room in the cellar (which has the boiler and he heating in it - so running water is possible) over the weekend and finally got to av a first experiment yesterday evening. I usually shoot colour, but have a black and white film from a course I did in the spring, where I also got to process the prints (which is what gave me the idea to do it at home too). What can I say - the end result yesterday was a nice glossy white sheet of paper I very carefully rinsed the trays I would be using and wiped them nicely clean with kitchen roll. Added water into the last tray and put the developer (which looked almost completely black) into the first tray then the stop (very strong vinegar smell - rather yellow) into the second and the fix (had turned the plastic of its bottle black!) into the third. In all three cases I used the ready mixed versions so no idea how old they were but the guy who sold me them thought they should still be OK. Then I turned the light off and was left with the orangey glow of the safety light. Lined up negative - got in focus - got out paper and set the time to 9 seconds - then removed the red filter from the enlarger and hit go. after 45 seconds in the developer I had agood idea nothing was going to happen but turned the sheet over and carried on for another 45 anyway. Then went through the process of stopping, fixing, washing and drying just fo practice. Long story but short question. Where would you guys recommend looking first to solve the problem. My guess would be the chemicals (or maybe the paper). Does anything in my description strike you as very wrong? Thanks for any help.
