I just did my first printing session ever last week... it was contact printing as well. I printed an 8x10 contact print of a single 8x10 neg using a lamp. I wasted about 10 sheets thinking my paper pack had been exposed to light and it all came out black... until I discovered that my tiny lamp had way much more wattage than I expected!

I can't wait until I have all my testing done, some bigger trays, and some nice, big paper :-) Addiction (and poverty), here I come!
