[Tig] PEC limiting MK3

[Graham Collett]

the only official filter for the optics of an Ursa was a Kodak made "shading filter" that was made because some films polarised the light going through them and that ended up as a green magenta tilt. If you cant get the filter then you can do a manual shading offset ..but you'll have to keep doing it different as different film react in different ways.

At one point there was a filter installed by Bill Hogan in LA (the
providence of which I don't recall) that improved Ursa shading in the
blue PEC significantly. Before filter, impossible to get flat blue
across the wfm; after filter flat. I'm not sure if this is the filter
you're referring to Craig.
