I have lower-mid range consumer LCD projectors, equipped with UHE mercury and metal halide lamps, and I'm trying to manually hack the colour balance with an incomplete set of colour settings, most of which I have never used or don't act like they should because the spectral output of the projectors is different from what the manufacturer designed it for.
You have ultra accurate colours, I get completely broken colours. So yes, it's obvious I'm going to see colour problems you don't have.
I've run out of ideas for the projectors, their colour settings are designed for fine-tuning, not for the massive corrections required. My only hope now to try and fix the colours is to find computer software to modify the colour space outputted to by the computer, use the maximum brightness modes of the projectors and hope the colour correction won't kill too much light.
I have two eeColor boxes that I got originally to use to color correct my Dolby lenses. Never bothered, because the Dolby lenses messed up the colors so much I felt it a lost cause.
However, they may be a good solution for use with the Omega lenses. Running one box on each projector, I will be running calibration on each eeColor box, with the lens attached to each projector. The box will then automatically apply color correction for each projector/lens combination.
I expect this to work very well, however I expect to lose a lot of light, much more so than just using the lenses without any color correction at all.
I think I will end up conducting most of the tests on a much smaller screen size, due to the light output on my projectors.
Regarding your color issues, it may well be that the color filters in your projector do not offer a broad enough spectrum of light output at the respective color bands. I haven't played with the Omega filters at all yet, so I'm crossing my fingers that this doesn't happen with my JVC projectors as well.
But I do still think that a spectrum filtering system such as this would require a serious light cannon to get satisfying output on a big screen. The polarizing lenses seem perfect for my JVC pjs right now, but I'm keen on getting the best out of the Omega lenses for when I upgrade my system for a new HT room I'm planning.
I do think that the Omega filters, on paper, are a better solution than the Dolby/Infitec system.
