Now that I've finally done 2001, I'm looking at Art's shot and trying to figure out which one is more accurate in color.

Opinions? Sorry I was not able to get the exact frame. It's a PITA trying to pause my Toshiba Player.

Cliff,

Are both of those screens taken with the same camera, that looks like a pretty dramatic difference if both displays are calibrated.

Nope. Not the same Camera. I believe Art used a SLR for his shot.

I'm curious as to the color of the chairs especially.

I think the chairs ar more accurate on the crts, more of a red- maroon than orange, but there seems to be a pinkish error that should not be there.

Cliff- it's impossible to tell because I don't think the white balance on either camera was accurately set on either shot. If both have been calibrated by Ken to D65K, sure the primaries/secondaries are different but the difference shouldn't be that large.

Those 2001 shots are amazing... This whole thread has been amazing.... I see Mr. Bob has posted some shots of his RPTV. I know another thread was started due to non-CRT PJ posting pictures. Would you guys mind another RPTV Owner posting some screens from his CRT

Nice shots guys. As for the 2001 shots, I definitly think there's something wrong with the color balance on the cameras on each shot. There's just no way they'd be that different if they were both calibrated to D65 with the calibrator.

Okay random question. What are you guys using for test patterns for the PS3? I need a pluge pattern with BTB, 2 IRE, and 4 IRE like the one on DVE. I know the blu rays have 4 internal patterns, but they don't have one I can use to set brightness.

Just terrible Cliff. Your second image doesn't work because you're a nasty hot-linker, and in your third post, the first image doesn't load. Cliff, perhaps you should use this forum a bit more .

Okay, then here's my contribution from my Hitachi 57F59. This was a shot Mike had from Planet Earth. I think I finally have the white balance figured out. And I obviously don't have it as dark as he does. The one on the left is Mom.

You guys might want to go back and find the stuff I wrote earlier on this thread about grayscale vs. color decoding. They are NOT the same!

The grayscales on the 2 displays in question are pretty much the same, if not completely identical. If both were set by Ken, I am sure they are identical to each other. The whites are cream white, just like they are supposed to be, the gray of his suit is the same in both cases.

Grayscale is STRICTLY for the b/w info, when there is no color. There is no color in the white of the background. There is no color in the guy's suit. The blacks have no colorations at all. All is as it should be, on the grayscale, on both pix.

The color comes in on the chairs in the background and on his fleshtones, and yes those are massively different.

This is done early on, most likely in the scaler in this case, but in any event where the colors are deciphered. To have something show up in pure red on one gun, that section of the pic in the blue and green guns is nonexistent, it's black. To have something show up in pure green, blue and red are nonexistent in those areas of their guns. NONE of this is dependent on how the grayscale has been set up on that particular display. The grayscales can be totally identical, and still have these massive differences show up where the colorations are concerned. That's color DECODING.

Guy Kuo did an incredible writeup on this years ago somewhere around here, probably at the SPot. Have no idea how to get ahold of it now, it was years ago, but as the designer/creator of AVIA, he definitely knows what he's talking about, on this type of thing. I read it rabidly, and soaked up ALL of it.

The color decoding is what makes those 2 pix different. It is what would have to be attacked, to get them to be the same. Not the grayscale.

Now whether it is in the cameras involved or the pj setups involved, THAT is still undecided...


Mr Bob

PS - awesome shots, guys!

Mike, I think you have definitely nailed your colorations and fleshtones, tho we wouldn't know for sure without HD color bars patterns - like those from my Accupel - and complete color isolation to work with, which is obviously easy with front pj triple gun tech. Just cover 2 lenses at a time. You've obviously gotten it incredibly close, enough for delicious suspension of disbelief in any case, and probably perfect. I think it would fly at 100% efficacy, if double-checked by my equipment.

And even if your grayscale has been set by optical comparator, I think it's excellent right now, and don't think you'll improve it using a color analyzer. The Runco guys held a color analyzer shootout a couple of years ago at CES, and guess what they used for the original setup that everything was based on?

An optical comparator!


Cliff, I love the transparency of your starfield shots, how that ship just hangs there in 3D, with no haziness around it. Absolutely crystal clear!

And Merry Xmas to all!

I see the link, but your shot is not displaying on my monitor. All the others are, including your other shots. Is anyone else having problems seeing this shot?

Nice shots, on Blade Runner. Your convergence is very tight.

Not as transparent as it could be, tho. When you cleaned your optics, did you do the deeper optics also? Good that you cleaned your cam's lens, I know that has played a part in the past, on your shots being more bleary than they shoulda been -


Mr Bob

PS - (later) - yeah, thanks for fixing it, works now!

Fixed. Just uploaded another picture. It was there at 1:30AM, really.
Blade Runner isn't me, but I'm sure BFJ will appreciate the suggestion.
Have a great holiday.

I have a A2, and page 35 of the manual shows frame by frame playback. I downloaded the A20 manual, and it looks to be the same. Page 35 is (I hope) attached below.
Hope that helps, since you seem to be doing just great otherwise.

Yeah, but the only thing that sucks is EVERY disc I've used so far does NOT support frame by frame advance.

Happy Holidays.

So frame by frame pb is how to get rid of the pause bar? I need to know how to do that!

If the disc does not support that, perhaps slo-mo? Works on my DVR...

Mike, how do you get Image Shack to not make the shots they send up, into a link to their site automatically? I can manually strip that link stuff off, but on multiple shots that takes forever...

Mr Bob

I select "multiploder" then upload the files to a folder that I place them in from the camera. I usually delete the ones I don't want to upload. And I only choose no more than 4 at one time. Some times I'll do three at at time, because the more you do at once the slower the upload.

Once I get them uploaded, that's when the manual parts comes in. If a group of three is chosen for upload, I'll have to copy from each of the three one at a time. And I've been choosing the one that starts with "[IMG]"

Now that's about all I know to do. This camera stuff is still rocket science to me..
