Actually, I've heard that the DV500 tilts toward the warm si - "Perry"


Since I've been 'quoted' slightly out of context, I'd like to emphasize a
few of my findings:
1) The GY-DV500 Color Matrix caused too high a saturation level (at least
for my taste). It didn't particularly warm the image but facial tones look
too red simply because the chroma is too high. I have been told by JVC that
it was specifically designed for the US videography market.
2) The Color Matrix is not user adjustable, but it can be turned off. The
chroma is then too low. Unfortunately there is no overall saturation control
either.
3) The GY-DV700 has a much better adjusted Color Matrix setting, influenced
apparently by the BBC. I found it just about spot on. This camera is
designed for the broadcast market.
4) I have found Sony cameras to typically color balance to a neutral tone.
Since some other cameras (often with Panasonic CCD chips) have a more 'warm'
tone, by comparison the Sony looks blue/green ('cold') but this is an
illusion.

Skin tone detail on DSR-300 - "Perry"

>Does any post production software have this feature? Premiere V6.0?<
All cameras have what used to be known as 'Aperture Correction' to improve
apparent sharpness of the picture. To cut a long complicated and
controversial subject down to a few words, most cameras add extra 'edginess'
to give subjective 'life' to what otherwise can look like a 'flat' picture
even with good resolution. Unfortunately this can be particularly
detrimental to faces, especially when the talent is the wrong side of forty.
Somebody (I forget which company had it first) had the bright idea of
selectively reducing the edge correction on the facial content, using a
colour detect principle.
Over edgy pictures are notoriously difficult to improve in post, so trying
to effectively apply the Skin-Tone Detail feature in post would also be a
lot less successful than doing it in the camera.
