Also, the non-linear response of the vidicon tube produced a cross-modulation between red, blue, and luminance that tended to desaturate greens and emphasize reds and blues. Don't know what the target material was in a Cosvicon; it could have improved the sensitivity and non-linearity.

Well, it will be an interesting experiment. I was actually wanting that 'smeary, noisy' business; I've been looking a lot at CCD and vidicon video images and I see that vidicon tubes in general appear to give a 'vintage' feel to the footage; kind of like listening to a scratchy old LP. I have seen some attempts to make modern footage look like old video or Super8 footage, and I'm not convinced it works. I have a project in mind that will requires the use of old-looking footage, so I thought what better way to do that than to use an actual old camera? I may desaturate to B&W anyway, so colors won't matter too much.
Thanks for the comments!
