Re: The Epson LPE Filter. Over 1600 Color Correct Lumens Out Of the 5010/5020 6010/6020? A Detailed Review.

I'm still waiting on a new PJ from Epson before I do any more testing. They're hand picking me a good one, they say, as I've had three bad ones in a row. Both Epson and Best Buy are out of 5020s Nationwide. My guess and my hope is that Epson noticed a lot of returns and stopped production to fix quality control problems. Hopefully the next batch will have fewer problems.

There's a guy on AVS who will be ebaying 4 of these filters soon. I'll try and give a heads up here before that happens...

I have a used iscan Duo VP coming. I'll run a Grayscale calibration with that and post the results too. Also, there's a guy on AVS who's going to run a 125 point calibration with a Lumagen Mini 3D. Should be very interesting to see the results of that!

Merry Christmas!

Do me a favor Nak, take a reading with your i1pro of a thick sheet of white paper. And then take a reading with the filter in between the two and post the results here. I'm certain I could find a filter that may fit.
Well, that didn't work so good. I used the panel of rolled Glidden Diamond 450 that your sample was cut off, so you'd have an identical sample. here's the readings: 246, 246, 243 for the Glidden, 28, 16, 26 adding the LPE filter on top of the Glidden.

What I'm thinking is to use my diffuser and take a reading off of the PJ. I'll use a 100 IRE white field and adjust the PJ for perfect neutral. Then take a reading with the filter. How does that sound?

I guess the first readings I took would work better if you were measuring filters at a store. The light is going through the filter twice, which accounts for the very low readings. If you got identical readings off of a filter using the Glidden rolled sample, it should be a match. BTW, I initialized the i1 Pro just prior to taking the sample.

Edited to Add: Not sure how well the measurements are working. I'm getting pretty different results every time I measure. The problem is there's a lot of light being released on the "through the filter" shots. I tried throwing some black velvet over the whole thing, but it only helped a little. I think there's reflections from the frame and the filter getting mixed in with the measured light. Also, I get slightly different results off the Glidden if I move the sensor around. Small differences to be sure, but they are there. I get identical shots with Glossy Epson Photo Paper each time.

BTW, I watched the Imax Grand Canyon movie last night in 3D on my 138" white screen. Gain is probably around 1.0 to 1.1? I found the picture pleasantly bright, and I'm sensitive to dark pictures. I was using 3D Dynamic and the LPE filter. Colors seemed natural and skin tones all seemed natural as well. I thought the picture was gorgeous, even though I have not done a 3D calibration yet.

3D Calibration added to Post #5.

@ Yiannis: LOL those are just numbers to help identify the color of the filter itself.

Yeah, that was a 100 IRE image. I adjusted THX mode as close as I could to dead white. I saved that reading and then put the filter on and read that. I figured it would be possible to determine the tint from that. It translates to a RGB value of 255, 214, 244 or very close thereabouts. Now, how you determine the proper opacity is beyond me. I guess I should have written down the "Y" values as well... Or could you use the calculated Y off of BabelColor? I got this just by moving the pointer around the CIE diagram till it read the right xy coordinates. At any rate I think it worked out OK, eyeballing it that looks like the right tint.

Looks very nice. Wonder whether this will work with 3010.

Anyway, still no luck in finding the filter separate in Europe. I have the google alerts setup. But almost all those alerts are about this thread and the avsforum thread. let's hope something shows up.

Does the filter look similar to this one in color?
I'll try and take a pic of mine with a white background, but I'd have to say looking at that pic that the LPE filter is a lot less opaque...
