Four 24" 18W fluorescent tubes with a high frequency ballast and brightness control, arranged in a square around the target. It's been a while since I last measured the output from such a setup, but I reckon something like f8 at a sensible (reciprocity-free) shutter speed will be no problem. The target is a ColorChecker Passport, opened at the colour patches (Gretag-Macbeth style grid) and warm/cool/grey patches. I don't know what the patches are made of, but would assume pigments of some sort.What film you choose will also depend on how much light there is and what you are photographing in it - are the colour-charts made of artificial paint, ink, natural pigments, a wide-range of colours vs a limited set, or ??
No output - they are for comparison with other films (Velvia 50 and 100f, and Ektar 100).What will be the final output that you require? RA4 prints, B+W prints, projected-slides ? Transparency-films are a bit of an orphan child for reproduction these days, especially as there are so few left, and you might want to stick with neg if you need prints at the end of the process.
