Is it perhaps of a desire to return to these less electronic evocations of color and feel that we?re now seeing a returning interest in film origination? We?ve had a few discussions of early color processes including potato prints and Autochromes on the TIG.

Rob I agree in this era of 4k, 6k, UHD HDR and so on there is definitely a desire for some cinematographers to not follow the trend. The "less is more" adage finds here a nother meaning. However I would like to see improvements in color separation. It is all about resolution these days because that's what the audience is looking at mainly but we as colourists would prefer get a wider range of colour.

This comes off the 'Autochromes and Impressionism' topic. People used to print onto films with coloured bases, or imbibe dyes into the gelatin to give a colour 'mood' to the shots. Dying a film yellow or orange also made it very hard to duplicate. There is a peacock blue colour. People cannot get this colour on modern RGB displays. In a tiny special case, our gamut has actually got smaller since the 1920's. I have a 2-pixel display. It uses a small filter-wheel projector (I took the filter wheel out) and a graded dichroic. This means the two pixels (either side of a circle) can have an arbitrary spectrum. The projector pixel is less than 2nm on the dichroic, but the dichroic spread is about 7-8 nm. I experimented with matching the single wavelengths, and it pretty much agrees with the theory - if you are mixing with Rec-2020 primaries, the most out of gamut colour is about 500nm, this blue-green colour. It lies off the blue-green edge of the gamut triangle, opposite the red corner. How many wavelengths is enough? Adding a fourth primary at 500nm would help a lot: you get all the blue-greens without losing saturation because your green cross-couples with red. Beyond that, you might have near and far versions of red and blue: the far versions are more saturated but less efficient, and different people may see them differently. There is even a good reason for adding a broadband white channel. A white mixed from three wavelengths will appear different colours to people with slightly different vision. However, when you get to six bands, you can probably mix a pretty good white from that. Cheers Richard Kirk -- FilmLight Ltd.
