Doris Mitsch writes about her technique:
The process I use for some of my pictures is a bit unusual, with digital technology replacing not only the darkroom, but the camera as well. I sometimes (but not always) use a flatbed scanner as a camera, which offers interesting opportunities and limitations. Unlike a traditional camera, it captures an image by slowly moving both the light and the lens across the subject, essentially lighting and photographing it from multiple angles in one long exposure. This produces a single image stitched together from thousands of tiny slivers, to which I then make endless, minute adjustments. This offers a view that can’t be seen through a camera lens or the naked eye, and illumination that can’t be duplicated with fixed lights. It also offers a uniquely detailed view, as I magnify each image and work on it down to a level of detail that will never be seen in the finished print. Full-resolution prints of some of the images can be as wide as sixty inches, and enlargements as big as 300 inches (25 feet) wide have been made without loss of detail.
People sometimes refer to this kind of work as scanner photography, scanography, scanograms, flower scans, scanning, and so on. I still call it photography, because a photograph is a picture made with light, and today there are many alternative processes for making photographs, including various camera-less methods.
