I would also like to raise at least one other thorny issue regarding the recording of archival documents. Folks from Kodak & Fuji are welcome to jump in anytime that they wish. ---- We have for about a century accepted Maxwellian tr-color recording (RGB)/(MCY) color photography. It is well acknowledged that this kind of recording is a major compromice on the color spectrum. It looks good to the average person and in particular does a good job on flesh tones so it has become widely accepted for the recording of visual material. However, this kind of recording hevily weights the reds and indeed records some infra-red information. It records little or no UV.There are older means of photography , such as the Lippman process, which due /do not rely on the spectral characterisics of dyes for their color imaging. They simply record spectra.
Now, that we have sophisticated elctronic spectrum analysers, computers, all of this memery and what not. Whay aren't we recording spectral images? Is anyone out there developing spectral cameras? Or are we forever condemned to the Maxwellian compromise?
