Steve...

I agree with your statement that ASA "should" be invariant. However, in my own tests on a Canon XL2, I noticed slight variations in the ASA value with changes in shutter speed. This can only be explained, in my mind, by theorizing that the sensitivity of the sensor varies with exposure in a non-linear fashion that isn't compensated by the camera's internal mapping. Another possibility is that the non-linearity is compensated in the light meter calibration. Testing with a separate light meter should answer this question.

[QUOTE=Paolo Ciccone;483025]Hey Enzo, e tu lavori a Hollywood e Cinecitta' ? ;)

"If you do broadcast work normally, TC might be reproducing "illegal" levels. Of course you can reduce them in post but you're settings require less manipulation. I'm aiming at making the HD100 as close as possible to film so I didn't check the values against broadcast levels."

Please forgive me if I get this wrong. I am looking to set up my HD201 with the TC3 colors. I think these settings might be what I am looking for. You say that the TC may represent illegal levels. In what way? I am shooting for broadcast quite often but am not used to setting up my camera, tough Eric Gulbransen has given me some confidence I can. Should I not do this then?

I am also trying to match my HVX200 to the 201 and I am looking for filmlike colors. Thanks in advance.

By the way, this forum is great.

Svein, it you have a HD200/250, you should use my TrueColor HD200 either version 1.0 or 2.0, the color matrix for the HD200 is completely different from the HD100 and the settings don't apply.
My comment about the "illegal values" means that the camera can produce digital values that are beyond the range of SD broadcast TV. They might be. It depends on what and how you shoot it.

Joe, Motion Smooth should be yanked out of the camera, if possible
Turn it off, for the love of God man, turn it off ;)

Nope. TrueColor HD200 is at http://paolociccone.com/TrueColor-HD250-part2.html
Alternatively I have another configuration adjusted for Nikkor lenses but that could work for the stocker as well: http://www.dvinfo.net/conf/showthrea...147#post807147
