Liquid Light in Torrance, Ca. sells a kit for $2500 which contains the Polaroid Palette, two film backs (one for slides, one for prints), software to drive it, and a heinous box that prevents you from ruinning their software on a machine without it. It's a pretty good system, and does a reasonable job. It only has two problems. The guy that wrote the software that drives the thing did a dumb thing in that instead of using a look up table for the exposure values (one value per RGB colour tick per r/g/b filter) he built the exposure table by computing it, when the program starts up, from the values of the filters, and the colour values of the films. Well, he was a reaonable engineer, and it works, but it could be improved on. This manifests istself in the worst way when you are doing a slide with a lot of blues. It translates them into a about 6 shades of blue. Other companies that use the palette spend a lot of bucks and pay an optica engineer to develop an optimal exposure table. The other problem of course is the stupid box. What it's there for is to prevent you buying a palatte at the normal retail price of $1300 and using their software. At any rate, if anybody wants to do some serious playing around wit this thing, I have a driver I sorta wrote once, thats about 7/8 finished, and the CORRECT film exposure table. Email me. The market has been a little soft for Liquid Light in the amiga area. But they double the price, sell them for the Mac ][ and then sell like hotcakes. Sigh.
