I have done a few (more like 10) runs of contact prints, using LPD (1:1), TF4 (1:3), and Ilford Ilfobrom Gallery FB paper (Grade 2). What I am running into is making exposures of 8-10 second produces nothing but solid black. I found that an exposure of 1 second (literally closing the lid and open it right back up) will give me an image. I tried taking out one of the bulbs but that only gives me 1 more second and an uneven exposure.
What are some thing I can try to get better contact prints using what I got?
P.S. The bulbs are 3" below the top pan of clear glass the negative and paper sit on.
