ok I changed the test picture a little bit: added a 'L' and 'R' on left and right view and saved it as P and X versions:

Hi pixel... I wan't to challange you on this old statement.

1) What glasses did you use? The cristalis3?

Could you test some other glasses? I want to know, if these things are valid for today, too.

Maybe you could test the cheapest glasses you can find. They could be used for other users as second choice in emergencies ;-)

i cannot download werners test picture :(
Can somebody send me?

Even the 3d-hdv.net doesnt work now..
I like to hear more ghosting test of different polarizer filters (linear, circular)
who has dual projector setup with silverscreen, please share the experiences.
what about cheap, plastic filters? is it worth the money?
(for eg. from http://www.polarization.com/polarshop/p ... ucts_id=34" onclick="window.open(this.href);return false;
or from ultimate3dheaven.com the circular one) anyone have this?

thx!

great test, I did try it on my zalman trimon 22"
I'd say:
white square = 25%
black square = 0% (with very little ghosting inside the black square)
I also tryed with realD glasses but it's difficult to say as the ghosting parts turn to purple
so...
white square = 35/40%
black = 45/50% inside the square
if I turn the reald glasses some degrees, then it get the same results as the zalman glasses

I put away my sparfilters for a while for testing how normal high quality polarizers from polarization.com performs with my lcd-projectors. I miss the high lumen of course but ghosting rejection so far is just as good as with the spars! Still 15% white, 0% black ghosting with Freke's image and 10% white, 0% black with WBloos image. I've been gaming for four hours with these filters and nothing have happened yet (burnout). I get back in the dual passive projection thread wether or not these filters are suitable or not. 8)

edit: Fixed mixing of colored ghosts. :roll:

That clearly shows the main issue with iz3d ghosting is color tinting. It's much worse for the left eye and is very distracting when coupled with ghosting. Waiting for new glasses before retesting :).

Hey i just discovered Werner's black&white ghosting test.
It's excellent : much easier to use than the previous ghosting test I used.

On my Zalman 22" i get 40% white ghosting, and almost 0% black but there is a very very slight darkening the scale isn't fine enough to measure so i'd say aprox 1% black ghosting.

"On my Zalman 22" i get 40% white ghosting, "

How do you test it on Zalman?
Load the picture to stereo photo maker and hit F4 full screen?
is it side by side in parallel format?

yes it's that easy.
Don't care about side by side or crosseyed, there ar L and R markers to tell which eye it corresponds to, ust press the swap eyes key if it's reversed (default key : X )

Just discovered this thread:

My planar like setup using 2 hyundai W240V2 + industrial Saint Gobain antelio as a transparent miror, glasses used: cliped from u3dheaven, without calibration, I get:
My white ghosting is invisible.
black ghosting is between 5 and 10%.

Nice! Finally some datas for a planar rig. I say that's a pretty good result!

Just tried this with my samsung plasma and elsa shutters. The ghosting is really bad though i cant get a % because the bars? What causes this? The glasses?
