    As the nephew of both Fukuhara Shinzo and Fukuhara Roso, I became acquainted with photography at an early age. In the camera club at university, I learned something about taking photographs and darkroom techniques. Interested in scientific photography rather than the photojournalism and salon photography then dominant, I had to make my own way, building the special equipment needed in scientific photography while studying booklets from Kodak. There was much to be learned about using cameras, lenses, film, and other equipment effectively. Over the nearly forty years since I became a working adult, I have been photographing orchids. While tending the orchid collection my father left me, I have focused on recording their flowers, as is, as garden plants under cultivation. To record the beauty of the orchids' flowers, I have used a variety of approaches, including adjusting the position of the flowers and camera, using a bug's-eye view, to capture a sense of the texture and feel of the flowers. Here I have recorded some thoughts on taking such photographs.

    The author participated in the HUMI Project, Keio University in 1997 and had been involved in digitizing rare books such as several copies of the Gutenberg Bible for more than a decade. For the first time in this article he describes his own feelings on photographing rare books, expresses sensations felt in the sessions at the photographing expeditions to the overseas libraries for digitization of rare books and talks about thoughts on what the good digital images of rare books are.

  • Electron Transfer Mechanism for Dye Sensitization II: Adsorption of Dyes to AgBr and Vacuum Level Shift

    A model proposed in the previous paper for the vacuum level shift at the interface between AgBr and dye as one of the keys for the establishment of the electron transfer mechanism of dye sensitization in photography was examined quantitatively. It was found that the shift was composed of two kinds of potential differences with opposite signs at the interface caused by the orientation of dipoles in dye molecules to the interface and the increase in the population of silver ions at kink sites of AgBr surfaces owing to the coordinate of lone-paired electrons in sulfur atoms in dye molecules to silver ions on the surfaces, and that the former was predominant over the latter. The result has provided an example of the vacuum level shift at the interface between organic layer and substrate other than metals.
