    was reading an old thread regarding the use of FLD filters fitted to the ae300 with regards to improving pic quality. just wondered if anyone is using them and there benefits.

    Colour correction filters only really work if you can recalibrate the colours correctly to take full advantage of them. PJ lamps are red deficient, so the green and blue has to be reduced to get the correct colour balance, and this will reduce image brightness and the contrast ratio. With a CC filter, it will optically cut the green and/or blue so you can run with higher contrast. The image will be dimmer than normal, but you will have a better black level, and because you can use more green and blue than you could without the filter, you don't lose quite so much brightness.

    Some projectors benefit more than others. With an NEC HT1000 you can get approx 900:1 CR more contrast using an fl-day, but something like the Optoma H78 will only get another 300:1 with the same filter. Finding the perfect filter can allow you to run with red green and blue at their maximum while still getting a good colour balance - ideally you should aim for D65 though.

    cheers gary invaluable imformation as usual, will have to experiment. although the contrast on the panny is quite resonable.

    You could try the search both here and over on avs and see if the filter improves the CR enough to buy one. If it does you may be able to use someone elses settings for a reasonable result, though they can vary quite a bit from identical pjs.

    If you want to experiment with the CC20R and CC10Y instead of the FLD, give me a shout.

    I'ev got an ae700 running with a B+W KR-6 as recommened on the avsforums and cinehome , it makes a small but not huge improvment in video mode which without the filter looks god awful the colours are a lot softer and black are defo blacker , for £35 it was a worthy upgrade (not as bigger diffence as upgrading to a HDMI dvd player from scart !)
