Only macro taking lenses will be good for enlarging. Do not reverse them unless you are making "enlargments" smaller than the negative.

Just to try them out, out of curiosity. I have a pretty good Meopta enlarging lens, anyway. But what now - should I reverse mount the lens? As the magnification is way larger than in taking even macro photographs, no? Or do I have it mixed up? I always thought that for depth of field/depth of focus computation for enlarging, the negative is "subject" while the paper on easer is the "negative", is that right? So, because the magnification is so big (~15x in my "normal" large prints), how should I position the lens? Rear optical group nearest to the "subject" (ie negative in holder), if I am right? That will make it harder to get a proper adapter, as I will have to get one made. Why I am interested in this - I would like to know, how the different qualities of different lenses, which are unmeasurable as lp/mm (which is meaningless anyway in reality because you rarely shoot subjects of 100% contrast lines), would exhibit in making prints. Good light, Frantisek Vlcek
