Dear all, I just borrowed a colorfact software for calibrating my epson TW-600 projector. After I finished with the D65 calibration, I found that the white is a bit yellowish, warm. Is it normal? Especially when I watch Phantom of the Opera DVD, the "think of me" scene. Christine's white gown is a little orange. Have I set up incorrectly? Or the reference is like that, the gown is a bit orange under candle light?

Thanks

Is the projector LCD based? And what probe did you use?

If the Spyder probe ... then it overshoots by about 1000K toward red/green on LCD based displays.

Redo and aim for 7500K on diagonal toward blue. It will get you closer.

Hi Michael, Thanks for the quick reply, yes, it is a LCD projector, and I am using Spyder probe. Is there a way to change the calibration setting to aim for 7500 instead of D65 on the software? What probe is better for both LCD and DLP projector? Thanks a million

Greetings

A I1 beamer spectrometer is better. Also works with the colorfacts program.

You can just visually aim for 7500K ...(this is an estimate ball park) Use the target window ... note that the center is D65 ... and just aim to the lower left corner toward blue. When it reads 7300 to 7500 ... you are in the real d6500K range.

The meter actually got you to 5500 to 5700. It is a weakness of these probes on LCD type projection units. It has something to do with the bulb and the light that comes off it that throws it off.

Oh, I see. Thanks for the tip. Let me try that tonight and see.
Sorry, two more questions, should Christine's gown suppose to be white?
and where to get the I1 beamer spectrometer?
Thanks

Gretag mcbeth ... try ebay first ... it's pricey at retail. $1500
x-rite ... color photo color matching companies.

just try it both ways ... remember the settings of where you are and look at the new settings. Also good to look at grayscale bar charts ... it's not good to decide if a TV is right or wrong based on one movie and what we think something should look like.

Would the Eye-one LT be a less expensive (~$130.00) alternative or does it suffer from this also: If the Spyder probe ... then it overshoots by about 1000K toward red/green on LCD based displays.

I really don't know, but if it is designed similar to the Spyder, then expect similar results. And all pod based probes are designed similar to the spyder.

Only with a spectrometer, could you be more certain it wasn't being thrown off. And the least expensive spec meter on the market is the I1 beamer/pro.

The probes like the spyder work just fine on flat screen computer LCD monitors.

Hi Michael, should I only adjust the blue gain and cut, without touching green or red in order to adjust the color temp to 7500? thanks

Sure ... why not. Generally, we try to leave the green one alone.

All "pod" based probes do not use the same filter sets nor use the same calibration methodology which is employed by Datacolors instruments. Your results could be significantly better using a different instrument!

The spyder and the display 2/LT work very differently, the display 2/LT is a traditional 3 color probe (+ broadband white) using bandpass filters to measure each color. The spyder uses multiple high-pass optical filters and then generates the color measurement by differencing these signals in firmware. The spyder is much more prone to errors if used on display types that these high-pass filters have not been specifically calibrated for.
