Re: Projector Calibration? Waste of time!

2006-07-05 by mhovie71

Hi!

First of all, the PLV-70 is a high brightness unit (2000 Ansi Lumens),
so when it projects a white image, the whole room is not dark at all
anymore. The screen reflects so much light, that you can easily read a
newspaper in the room. That's why you can also tell if the white is
greenish, blueish or whatever. So in my opinion, I would make sense to
calibrate the white point - at least you could give the users the
possibility to do so if they wish.

Secondly, my Spyder2Pro hardware seems to be ok - I've successfully
calibrated 4 monitors with it and the results are very good. I always
liked the "After" picture much better than the "Before" one - flesh
tones looked more natural and the overal image appearance was more
pleasing. So "my Toyota is not broken", I should just not try to drive
it somewhere where it's not supposed to be ;-)

I guess the whole projector calibration process is somehow strange. I
can't imagine getting reliable results when the sensor reads light
from its own shadow. And my experience seems to prove that point. The
procedure as suggested by the calibration software is easy to follow
and you can't really do anything wrong. So if it still produces
results that are way off (and the hardware is ok), then either the
software must be buggy or the whole principle of the calibration
process has flaws. I guess it's the latter, otherwise I couldn't
explain why my calibration works for monitors but not for projectors.

Regards,

Martin

PS: I don't any reason to discuss this privately, as suggested by
CDTobie. Of course ColorVision only wants satisifed customers
reporting how great the product is, but a discussion group must also
have room for negative experiences.
