This is interesting.......but.....
Would this be best done as an optical effect with real filters.
Any digital 601 box would not have the dynamic range compared with an opt=
One of the great things about grading from film is the dynamic range, thi=
s seems the wrong answer.

For historical interest.......I designed a filter draw for the Ursa  4 ye=
ars ago. South London filters purchased the design of the Mk 1 version fr=
om me and have changed it into their own particular version. I offered it=
 free to Rank Cintel but they could not see a need for it!!!
I have re engineered the design since and it is fitted to many Ursa's aro=
und the world , the latest installed at Rushes is a 2 pack Filter FX kit.=

Filters have been used heavily for many years here in London and it is in=
teresting to hear the new surge of interest.
Kevin Shaw worked with me testing the design and he deserves credit also.=
 Kevin pioneered the use of the unit on high end spot's .
There are many copies around.
