    I got my HOYA FLD today and put in this pm, after a minor tweak of greens and brightness and contrast , the picture is RADically
    improved , did some phase adjust as well and the picture now has a truly CINEMATIC FEEL , much deeper ,richer and more involving picture.

    Even the Missus who rarely notices any of my tweaks!! Was noticeably impressed at the difference, her first words were
    'OH It looks much deeper!'

    It (or my tweaking) also appears to have had a positive impact on the dreaded VB's!!! which are all but extinct(much fainter than before).
    I was getting ready to upgrade my projector but this filter has certainly made me rethink that!!

    If you havent got one i give it my full recommendation!!
    for what its worth !

    Spacecat,

    Glad to see you got a result ! I had read loads of posts praising the Hoya both here and over on avsforum, but dithered around before finally getting my hands on one recently. It really does the trick.


    See ya,

    I was also lucky in that the one i got was a perfect size, all i have to do is just push it in to the lense and it stays put without having to use tape or any other form adhesive.

    Wish i had done this before!!:( :( :(

    I think i will now sit out this round of projector upgrades my projector is nearly 2 years old , i think i will give the HS10 and Z1 a miss for now(excellent though im sure they are) and maybe see what comes around next year (or if the prices radically drop!!)


    The trouble with this game is theres always something NEw around the corner!!

    I know I should be doing a search and reading thread after thread, but it's Friday night and it's been a long week! Any chance you could tell me a bit more about the Hoya Filter, your post has got me thinking. You can start at the beginning if you can be bothered 'cos I know nothing about them. Any info much appreciated.

    As im feeling lazy as well here is a v brief synopsis!!

    1. most Pjs favour green light

    2.Hoya FLD filter cuts out green light

    3.put Hoya filter in PJ

    4.Boost green and in my case blue

    5. lower brightness (in my case)

    6. do contrast adjustment to max detail

    Conclusion

    Picture now looks much more cinematic and 'DEEP' , colours look
    richer , more detail and contrast,picture looks smoother and less harsh and therefore more immersive.Either the filter , my tweaks or both have reduced the dreaded VBs to a point of barely there now and then.

    NOT BAD FOR £26!!!

    Sorry but what does VBs refer to?

    I'm in the position of having a hoya filter sitting on my desk but no PJ to try it on :mad: It's been on back order (the filter) since before xmas but my PJ blew up two weeks ago and I'm waiting on Panasonic to return!:

    Spacecat,
    I just have acouple of quick questions. What size filter did you buy (was it 55mm) and was it the HMC or standard FL-Day?
    What, if any, calibration DVD did you use?
    Thanks in advance,
    Tom.

    I bought a 58mm filter from a place in the strand London

    I used the best two calibration discs i know ,
    MY EYES!!! LOL


    I have no idea if it was HMC or Standard its what they had , it is however coated on both sides.

    I am projecting onto a light grey coloured wall

    Using a HTPC, ()Theatertek, windvd,Zoom Player and ATI player!!)

    I dont Chris for AE100 as I have a Toshiba MT1, however i just measured the lense with a ruler and then bough one that was a bit bigger so it would fit inside the protective lense casing

    Luckily for me (BY FLUKE!) the filter fits snugly into the PJ lense casing without needing to be attached in anyway

    Chris,

    I got a 52mm for my AE100, and with a narrow strip of masking tape on half the edge of the filter it fits very snug just inside the lense of the AE100. I think some others have got 55mm - I think they need to be taped on.

    You should try it - for £20 (or thereabouts) its the most cost effective upgrade yet, imo.

    Now - just got to find the time to do some Icestorm screen experiments !!!!!



    See ya,

    The filter increases contrast!!

    Light output is reduced but in a light controlled (dark) room it doesnt make much diffrence , the picture is a lot better though.

    In fact SONY are giving filters like this in part of the HS10 package

    Just got my HMC filter from the states last night Thanks to the person who recommended www.2filter.com). 55mm and taped on. (some people reported light scattering at the edge with 52mm). Definitely worth getting one for the AE100. Contrast is improved, and the vertical banding is reduced. The picture also seems more real somehow, I can`t explain it.

    I would like to know which type of filter you guys are using? From what I gather it should be a "hoya" filter whatever that means. When I look for these I am offered UV or Sky types?

    Please Help as I want to get the right one!:confused:

    Hi ninc,

    The filter is a Hoya FLD (Flourescent Daylight Fliter).

    whats the difference between a Hoya filter that reduces the green and a ccr filter that reduces the red.

    which is best or is it swings and roundabouts?

    Ninc0,

    the HMC (multicoated) version is more difficult to obtain (can be got from the States, do a search here to find details) and is regarded as being better than the normal version, which reflects some light backinto the projector. The HMC version is less reflective (presumeably because of coating). I don'tthink anyone has done side-by-side testing, so an informed comparison hasn't been published afaik. The normal one does an excellent job though and is well worth a try.

    graham.myers,

    The FLD is more commonly used with projectors where you can adjust the White balance, like the AE100 - you can adjust the R,G and B components of the white balance. The effect of the FL-d is illustrated here . You need to increase the G and B components once you apply the FLD filter - this brings better overall balance to the RGB components together, giving better contrast and better colour balance and better blacks. It corrects the overall "green" cast that is often seen in the projected image.

    Using a CC30R or CC40R colour correction filter is more commonly used with projectors which have the facility to adjust the Panel gain - this is normally done through the service menu - not accessable on the AE100. A colour correction filter cc30/40R effectively blocks a large proportion of the Green and Blue components, leaving the red component through - this is too extreme unless you can increase the gain of the green and blue panels substantially. An illustration of the effect of colour correction filters can be seen here for further information.


    All the best,

    Sean G.

    You'll need to put the filter on first, otherwise your calibration will have been a complete waste of time. Oh, I suggest turning on the PJ too ;)

    Well, I took the plunge - ( well for £16 I had too really ) and the filter now is attatched to my AE100

    I used the THX setup on R1 Attack of Clones for the setup - and have my player connected via component output.

    I have found that I did not need to alter the color settings, but both Contrast and Brightness settings had to be lowered by about 5 each. Does this sound about right ?

    Also - should I just stick with normal color and norma settings ? or should I have it in Cinema mode or anything ?

    Thanks in advance !

    Hi,

    I've ramped up the green +6, and the blue + 12 in the white balance ---- it corrects the colour after applying the Hoya. I'm sure you could get more accurate results using Avia or similar, but this gives best effect to my eyes when cycling through colour bar test sceens. If I leave the white balance unchanged, it gives a magenta cast to the picture. YMMV.
