Just got a cheap enlarger ($35 with 3 lenses) - cannot resist even tough I don't have any space to set as darkroom. For a couple of days, I did my own BW printing. My enlarging (dry) and developing (wet) space is separated. So, what I do is - expose a paper, put it into dev tank and after I was done with it, I went to my bathroom in second floor to develop it. Time delay for the paper about 15 to 30 minutes. So far, I can manage a "so-so" prints (yeah, it's from 35mm to post-card size...). Well, is there any rule about delaying paper development? Is my workflow will make any effect rather than directly develop after exposing? Thank you.
