for a long time had i forgotten that the entire film strip used in a camera is photosensitive, and not isolated to a 35mm bias. using a holga medium format camera, with a 35mm film, i was able to cast an image across the entire strip. despite the perforations on the film, a certain portion of image is discernible at the top and bottom.
this medium format camera allowed me to control, roughly, how far along i scrolled the film before i snapped another picture. i wanted to try overlapping some pictures. i had mixed success. in principle i found that alternating, or being even more creative, with the mix of light and dark scenes mixed the best photographs on the negative.
this minor experiment was worthwhile, if only to conclude something quite simple about how cameras, and their films, work.
2400dpi
4800dpi
19200dpi
a recent discovery for me has been the ultra-high resolution scanners in the media labs of duncan of jordanstone. they are specially designed to scan film positives and negatives. i decided to push what 'ultra-high' actually means. it means 19200 dots per inch.
reference point = the majority of digital cameras record pictures at 72dpi
