Like one or two others, I have been looking to find information on how to optimise the quality of images from digital projectors. Much of the available information seems to relate more to graphics than it does photographic images. Interestingly there are International Standards relating to viewing hardcopy images, colour slides (both 35mm and sheet film), slide projector images, and monitor screen images, but not for digital projector images.
These standards were jointly developed for the photographic, printing, and other groups with similar interests like art galleries/museums. The standards give re-assurance that images will look as the originator intended where ever in the world they are viewed.
Returning to the digital projector situation, images are at the mercy of whatever projector setup is in use, so what looks good on one projector, may look bad on another, eg. a projector at another club. So maybe there is an opportunity to come up with a method of setting up a digital projector that other clubs may want to follow that achieves a more common appearance. To be taken seriously, this set up would have to based on strong technical merits, rather than some ad-hoc setup.
My initial thought is to explore methods of achieving the best visual match between a black and white image on a calibrated LCD monitor, and a digitally projected image. (Colour images would come later).
Rather than expand on this here, I would be interested to hear other members views before going further. If there is interest, I would appreciate some assistance with assessing image appearance to go along with my technical know how.
