Photographs in this gallery were created with the Rolleiflex film camera, a twin lens reflex, then scanned into my computer. The size of the negative/slide is 2.25 inches x 2.25 inches (6x6cm). It's akin to having a multi-megapixel digital camera, and it is four times larger than a 35mm negative or slide.
Not all of the pictures in this gallery are square. The beauty of the square format and the twin lens reflex is that it allows for cropping of the photograph, without having to turn the camera in a horizontal or vertical orientation.
