hookiefreak Posted April 10, 2006 Share Posted April 10, 2006 Hi, At the end of the month I am going to be using some MAC 300s. Is it possible to find out CMY values for different Lee Filters? E.g. the CMY values for L101. Any help would be great. Cheers,Hookiefreak Link to comment Share on other sites More sharing options...
AndrewR Posted April 10, 2006 Share Posted April 10, 2006 According to MagicQ L101 (yellow) is 0,0,255. So full yellow then! Check the search function, somebody out there has a spreadsheet of the cmy tables.Beyond that download an offline product like MagicQ or Vector and crib.

paulears Posted April 10, 2006 Share Posted April 10, 2006 excell lee spreadsheet for CMY conversion html Lee listing for CMY conversion May be of some use - it isn't, as I've found totally accurate, at least not on my kit - but pretty closePaul Link to comment Share on other sites More sharing options...
jfitzpat Posted April 10, 2006 Share Posted April 10, 2006 excell lee spreadsheet for CMY conversion html Lee listing for CMY conversion May be of some use - it isn't, as I've found totally accurate, at least not on my kit - but pretty closePaul FWIW I just tried a few experiments with the swatch book, a diffraction grating (Michita), and some glass dichro's. The table actually looks pretty close for the colors I tested, for example, L101 is listed in the table as having a small M component (about 2%) and, sure enough, it shows up in the real gel. But most CMY mixing schemes are not truly linear, so even if the table values were perfect I'd expect some tweaking to be involved. -jjf Link to comment Share on other sites More sharing options...

paulears Posted April 11, 2006 Share Posted April 11, 2006 and with my wash lights - it also depends which part of the beam you are looking at! Link to comment Share on other sites More sharing options...
J Pearce Posted April 12, 2006 Share Posted April 12, 2006 The other factor is that if you use pure CMY values to generate LEE colours the MACs won't match any tungsten lamp lanterns in the rig. I am working on a mixed rig this week, and the LDs assistant matched the movers to tungsten sources (S4 pars with cascade scrollers) just by eye.This means that when assigned to palettes the colours match up seamlessly.

tokm Posted April 12, 2006 Share Posted April 12, 2006 The other factor is that if you use pure CMY values to generate LEE colours the MACs won't match any tungsten lamp lanterns in the rig. What about sticking in CTC filter on the colour wheel? So that the colour temp' would roughly be the same as a tungsten lamp. Would that work?
