Brownie Box negatives are enormous. Each negative contains fantastic amounts of visual data. You can just keep zooming in, though the cheap meniscus lens eventually lets you down, especially at the edges of the photo. I took my 90+ year old Brownie 2a for a spin in Stoney Creek cemetery today. It is a light hog. Even a three second exposure in bright sunshine was usable shot, and the tombstones in bright sunshine look like sharp pencil sketches rendered on a gloomy day.
