Last night I was making some contact prints from some 4x5 negatives. I was very unhappy with how they appeared soft compared to ones that I had done months ago on someone elses enlarger. It was with the same paper. The only thing I could think of would be that my paper is old, which it is. Does paper do this when it gets old? Also, could certain glass cause contact prints to appear slightly soft? I'm not contacting through pages or sleeves. I'm taking the negative out and lying it right on the paper.
