What's the word on Kodak's Photo CD then? It's obviously designed as a bit of a (Canon et al) still video killer, but is it really high enough quality? I've heard the scanner that converts the 35mm negs to digitised images is 2048 elements wide. If this is along the 36mm edge of the neg, it only amounts to 57 pixels/mm. Even along the 24mm edge, you only get 85 pixels/mm. This doesn't sound very high compared to the highest resolution film (isn't Ektar 25 ASA supposed to be about 150 lines/mm?) What's the colour resolution? I gather an uncompressed image is about 18Mb, so at 2048*3072 (being optimistic) pixels we get 24 bits/pixel, which is fine. But the compression ratio is 3:1, so how badly does this affect the colour resolution? Or is it spatial resolution that suffers, or both? What capabilities will be offered by the Photo CD player? Will there be real-time panning and zooming of the images (shades of Blade Runner)? What about hard copy? Will there be affordable colour printers that give as good results as chemical processes by the launch in two years' time? Any informed opinions welcome... Pete XXX

It's obviously designed as a The digital cameras will not replace the photographic film. For other things then fast shots. For newspapers etc. I have also heard that Sun has liceded the technology from Kodak. This is a very interesting since then we perhaps wwill get a "cheep and easy" way to get images in the publishing programs. Is Sun devolping a device that can read the Kodak disks? When will we se it on the market? Or is Suns goal to provide the printshops with printers and computers? Sven-Ove Westberg, CAD, University of Lulea, S-951 87 Lulea, Sweden.
