May want to share your experience in using special coated lens that fix over the DLP projector len to enhance blackness and increase contrast & improve color. Present setup is with firehawk screen, HTPC, Dreamvision DLP 500 projector, Cinemaster video & WinDVD sound output.

Thanks

 http://www.2filter.com/prices/produc...tml#FLDfilters This will deepens reds, lessen greens, darken blacks (slightly), reduce brightness (very slightly), smooth out screen door (very slightly), and protect your lens. Most digital PJ uses UHP type bulb which tends to be too green. These filters will help if your PJ has the lumen to tolerate the slight drop in brightness. Make sure you get the all glass, HMC kind (hoya multicoated) to minimize heat damage and reflection (which can reflect back to the DMD chip causing reduced contrast). These filters don't really enhance contrast but they make the blacks slightly darker and deepens reds (correcting skin tone) making contrast appears better. These are great for the lens opening cover for your DIY hushboxes.

Huey,


It is interesting that you chose to use an FL filter which does exactly what you indicated because it is designed to compensate for florescent lighting.


Wouldn't a neutral density filter work better, like an ND2 or ND4. It would not create any color shift but would bring down the overall brightness so blacks would be blacker (compensating for light leakage) at the cost of overall brightness.


Kind of similar to using a gray screen.

Huey & Mouserider

Thanks for your input on the HMC, ND2 & ND4 lens. I guess it all depends on the actual projector lumums, throw distrance, screen material etc and experience.

Regards.
