Photographys. Bigger again?

To make enlargements over 50 x 60 centimeters requires a different working practice and a large darkroom.

If your negatives allow you to print them at 50 x 60 centimeters this is not the end of the story, you can go bigger with roll sized paper of 65, 100 and even 130 centimeters wide. But to go larger you will need a different method to produce them and a larger negative to start with which will increase the quality of the image projected by the enlarger. Your darkroom will need to be big enough to cope with the increased size of equipment. You will need an area of clear space that the enlarger can project the image onto whether it is the floor or a wall. Of the former the latter is the better way of doing things as you are less likely to get dust on the paper, it also makes it easier to dodge and burn if you need to.
