By the way, "red happy" seems to be the only major concern from people using the "TrueColor" file. Since red gain is set to 3, what have you found happens/goes wrong when that is lowered to 1 or 2?

Yes, I was too expecting the red gain to be directly responsible fot tha but after spending a few minutes with the red gain it was obvious that that was not going to yeld the expected result. The blue does it and I think that you'll be able to verify it easily. The reason why the red is at that level is that it places it at the right spot in the Vscope. Initially I gave more emphasis to correct position o f red and yellow as they are the major components of skintone. In fact pretty much everybody reacted postively to the skin tones of my configuration. Version 3 is an attempt to adjust it a little bit based on "real world" situations.

Can't claim I have come up with the name. It was part of the subject line that Tim D posted as a reference to my article. Then the name stuck. I'm not complaining :)

This post is really late in getting to the discussion but... have any of these tests been performed using a person as a subject to look at skin tones?

Hi i ve been using Paolo's TCV2 and now on TCv3 but i didn't set the color as he suggested, from my montior it's a bit too cold/bluish.

may be we separate the color from tone. as a matter of fact i never do color balance , but just set the either day light or tungsten. this is easier for me to make a plug in( i m using vegas) to correct the color in one shot.

my main concern is dynamic range as i realy want to creat a Digital "negative" to squeeze in more detail on both highlight and shadow.

both gurus are great , it will be even better if can work on a super dynamic raneg to go beyond 8 stops. i m from old school of Great Ansel Adams. so i guess 8 stops is just enough for me to work. -4 stops for shadows and +3 stop for high light.

does anyone try to use ultra contrast /digi-con filter to make acheive this?

Hi after i test all 3 , i tend to like "widlat2" becos the black seems to be smoother insetad of some darkess back is become very dark compare to deep gray
and i like the shadow area has more detail.

anyways this will give more room for em to do tone adjust at post.
color wise i think set as u like is OK, as i think different camera may be different.
