"Other" photographic processes
There are more ways than "pure" photography to capture a photographic image. One can place 2d or 3d objects onto photographic paper and then expose the paper in a darkroom, the opacity or transparency of the objects affecting the passage of light onto the paper, and then develop the paper as a normal print, called a photogram. The same kind of thing can be done with the objects placed into the negative carrier of an enlarger, if they are small and thin enough, resulting in spectacular enlarged photograms. Or one can simply scan things using a regular desktop scanner. These leaves are from the scanning process, which captures fantastic detail at high resolutions. If your scanner is set at, say, 2400 dpi (dots per inch) and your printing is to be done at 300 dpi (a good resolution for photographs), the prints can be 8 times larger than the original in length and width, which can turn a leaf into a great poster child for nature lovers or the eco-minded.
