I'd like some suggestions for colour film to make images of colour charts. They will be shot in lighting where the colour temperature is tightly controlled. I assume I need something that is relatively neutral/even in its spectral response, and not too saturated. Format is 120, and I'm looking for both transparency and negative. The choices for transparency seem to be rather limited these days, and I was thinking of Provia 100f. Any others? For negatives, I have some Reala - is this a good bet? Also, am I right in thinking that the colour temperature to aim for is 5500K?
