RS-1, Radiance Primary Gamut Correction - Page 3

Poof - there went the argument that it is not the PJ - that it is the digitally colored SeaBiscuit DVD....

sfogg,

A huge thank-you for those -15 comparisons. Looks like a new new purchase is on the horizon and if we meet someday several rare rounds on me.

Shawn,

"Any specific scene you would like to see?"

Seabiscuit took care of it, thanks.

The thing that strikes me about the screenshots is that it looks like I could (and I have) do the same thing by just turning down the color control.

I thought the trick was to reduce the green saturation *without* excessively desaturating everything else (leaving aside the excessively ruddy faces).

Post of the week!

I have a question re the Radiance product. My RS1 is driven by a Toshiba HD XA2 HD DVD player. I also watch some high def TV stuff - mainly sports. I like what I see re color correction, but the $4K price is making me choke, because I don't think I would have a use for anything else the product does. For example, I have no need for video switching. Would there be any other benefit to this product in a rather limited set-up like mine?

The public is to blame here too. There isn't a single display, on the market or previously sold that doesn't need calibration. Calibration won't make all of them "color correct", perfect gray scale, perfect gamma, etc. however, it does improve the picture (significantly on some). Being in the calibration business, myself, along with every other calibrator in the Los Angeles/Southern California area should be booked with 3-4 calibrations a day continuously. Problem is, the people that purchase the displays don't know any better, they are totally unaware of the errors in their displays. To the uneducated populous, more, brighter color is better..... Unfortunately these people make up the 90+% of the display purchases. These are the people the displays are designed around, the marketing studies, the targeted selling price, the needed features, etc. Manufacturers are not going to spend a penny on an additional feature that they feel they can do without (read as sell the forecasted quantity or more). It's all about profits.

Myself, if just for the business I am in, would like to see full controls on every display, and every display capable of accurate calibration results. I get satisfaction out of calibrations the conform to the standards when completed.

The future is in the consumers, as they demand picture accuracy, the manufacturers will conform because they will speak with their purchases. If JVC or any manufacturer can sell all the displays/projectors they can produce, why change? They don't care about anything more than the profit. JVC has probably had more returns of projectors for manufacturing malfunctions than the number of us actively concerned about controls to produce accurate picture output.

We are fortunate that the need for video processors started with the CRT projectors and has now carried over to the new displays. Jim at Lumagen, works with the input from a lot of calibrators, this is one reason there are controls on his video processors that don't exist on other VPs. This is also the reason he is developing a CMS while the others don't. Until the manufacturers are forced by their target consumers to produce accurate displays, an external VP, such as the Lumagen will be necessary for many.

I feel it is necessary to have a Lumagen DVI/HDP/HDQ at a minimum with the RS1, just for then needed 11-step gray scale and gamma correction. Unfortunately the uncorrected gray scale is not uniform and the gray scale is different with each Gamma selection (Normal,A,B,C). This can only be corrected in the Lumagen. With my RS1, since I don't have any steps in the gray scale that go plus green, I don't see many errors in flesh tones, other than those in the source. Color decoder corrections for the source also helps.

It seems that the current focus is on contrast ratio and rightfully so. Until the RS1, I didn't see a bulb projector, at any price, that I wanted to swap for my Marquee 9500LC. I am still disappointed with the RS1 black level, with the exception it is not as critical to a little ambient light.

The public just needs to become aware they are being cheated by manufacturers, selling displays that don't and can't produce an accurate image, based upon current standards.

Apart from the CMS the RS1 could benefit greatly from the custom gamma curves the Radiance offers. I think there would be benefit to tweaking the high-end to help or hopefully eliminate the wash-out effect sometimes noted.

You don't have much of a choice at this time, each one of your sources need different settings. You can use memories in the projector, however it is easier in the VP. The only thing that seems to be changing, price wise, is the display devices. Lumagens are basically the same price and I imagine the Radiance will hold it's price for years. Fortunately, the Radiance will be applicable to the next generation projectors and probably a few after that.

It all comes down to the picture. If it is not what you want, add what is needed or just wait till they produce what you want at the price you want. Another way to look at this, for $9K you can have a projector package that will out perform anything else on the market at triple the cost.......

Thanks Shawn.... Skin tone changes are dramatic!

There is the hope of the 500-100$ gregr CMS box. That is if demand is great enough.

Doesn´t the RS2 provide better gamma and grey scale controls?

Agreed!

Shawn,

It must be my monitor, because all of the before images look generally oversaturated and all the after look undersaturated.

I'd be interested in seeing the just the green corrected (my biggest though occasional gripe at this point, I must have gotten used to complexions), but if you say the Radiance can do it that's good enough for me.

I agree the "after" shots look more correct in terms of color accuracy, but undersaturated too. Too pale.

Which is interesting as I've often found the typical ISF calibration of many displays to be a tad over-rich for my tastes (I tend to back off the color a bit). So even for me the "after" shots are looking too pale. But I attribute that to being screen shots.

I presume that the Lumagen, like any good color control, would allow you to make the colors accurate, and also let you have a more saturated, or less saturated image to taste as well. (?)

Shawn,

"I'll give that a try and take some pictures of it for you. I assume you want Seabiscuit for those?"

I appreciate the offer, but don't spend the time on account; I've just a passing interest, as there's no way I'd spend that kind of money for the fix.
