I photograph artwork using a 4x5 sinar, and would like to be able to input infor mation onto the film, using some sort of large format "data back".I was thinking of a miniature led display inside the rear standard able to project onto the fi lm plane,driven by a keyboard device.The effect would hopefully be similar to th e edge marking for batch numbers used by the film manufacturer,and enable me to positively identify an object with an alphanumeric sequence,perhaps even direct from an existing database.Any ideas for this project? I would prefer to inp ut in camera rather than prior to loading the film,and I know it will be easy wi th digital but that's a still a few years off for me yet. Many thanks from a newcomer to this form of communication.
