TrueColor HD200/250 available!
 
Hi all.

TrueColor for the HD200/250 is finally available. This configuration took a considerable amount of time and effort. I wanted to be absolutely sure that this was the most accurate reproduction of colors that I could obtain with the HD250. It took several different approaches but it's finally available. I wrote, like I did for the HD100, a complete walkthough of the process and there are images that can be downloaded and examined independently to verify the results presented.
All the material is available at my site: http://www.paolociccone.com

Enjoy!

True Color Questions
 
Paolo,
first of all I like to thank you very much for your work. I liked your settings with my HD100 and now I will enter the data into my new HD200.

I have three questions:
1. You propose to set BLACK to NORMAL. Underneath this parameter there are two further settings, i.e., STRETCH LEVEL and COMPRESS LEVEL. To which values should the latter two be set?

2. With GAMMA you propose to set NORMAL. In my camera the values for GAMMA are: OFF, CINEMA, FILMOUT, STANDARD. Which value shall be set here, and which value shall be assihgned to LEVEL of the GAMMA setting?

3. Which value shall be set to COLOR GAIN ?

I would be pleased to get your answers.

BTW there are some difficulties in your web-pages with text which overlaps other text.

Best regards,
Joachim

It doesn't matter because the black is not stretched nor compressed. Those values are to be modified if you find yourself in a situation where you need to modify the interpretation of black because of specific lighting conditions. As TrueColor is designed to produce an image that is as close to reality as possible, blacks are not stretched or compressed.

My bad, it's meant to be Standard. Typo.

No gain.

Hmm, can't see it, except for the copyright notice at the end tht should be now fixed, together with the corrections that you mentioned. I tesetd it both with Firefox and Safari and they render it right. If you can provide a screen grab and information about your browser (name and version) I might be able to reproduce the case and put a workaround for it

Take care.

I think you must mean NORMAL gain. No color gain would render a B & W image.

So setting the gain switch on the side of the camera to "0 dB" should give you a black picture, right?

This setting has positive and negative values. "No gain" means no positive gain. To get a B&W picture you need to set the gain to negative values, in effect desaturating the image. Hence "no gain" means no increment or decrement, just keep it normal.

Thanks
 
Paolo - thanks for spending the effort and the time to post these settings.

I have been shooting with several variants for a while now, and can honestly say that your settings and others like them make the camera worth sooo much more.

I'm really glad that you and Tim and others are pursuing excellent color - those of us with JVC cameras can be especially grateful!!

Paolo Ciccone May 27th, 2007 11:25 PM

Thank you Jeffrey and thank you for testing the intermediate versions.
As much as I think that it's a good thing to have readily available versions of camera configurations I invite everyone interested in knowing more about the cameras to spend the time to read the article in its entirety. I tried to make the process as clear and as transparent as possible. Altough I verified the results many, many times I invite everyone to challenge and verify the results.

Paolo,
You are great.

Corrected True Color Values
 
Paolo,
thank you very much for your clarification. I have set the Camera as you proposed and will see the results soon, going for vacations to Lake Garda, Italy.

The problems with the text in my browser will be reported by e-mail together wit a screen shot.

Best regards,
Joachim

CSS-P workaround in place
 
Hi Joachim.

Thanks for the email. I can't test my pages on IE8 but I found out that Opera on the Wii has the same issues. Both browsers have bugs related to the treatment of CSS-P elements. I converted the page to use the less precise but widely implemented tables and now it should display correctly. I'm posting here so that all people affected are now aware of the fix. I still suggest to use the more capable and standard-compliant Firefox.

Thanks for the help.

Marc Jayson May 28th, 2007 04:09 PM

Thank you for TC Paolo!
I've been waiing for this.

(hahaha, I also have a Wii)

Heath McKnight May 28th, 2007 04:15 PM

Interesting; I'll give it a shot on my friend's HD200.
