It was standard practice to shoot on 10x8 trannie using a macbeth colour guide in the first frame.

As a rule the lights were polarised, you can get hold of the gel here

then cross polarise with a liner polariser on the lens, you can use a circular it makes little difference, use a spirit level and put the lens in the center of the picture using a slightly longer then standard lens, 100mm for Haselblad and a 240 for 5x4 would be a good starting point. To be honest a P65 on a sinar back is the most cost effective way to approach this but the issue of archiving will be a something to resolve. Shooting on black and white might not be the best approach
