Keeping it going
Hi
I have a pdf file from ARRI with more formulas than you'd like :-). Take
a look at it here ;

If this is the math for going from AlexaV3LogC to Linear:
(x 0.1496582 ? pow(10.0, (x - 0.385537) / 0.2471896) : x /
Based on that formula, the reverse should be:
x0.0106232?(log10((x + 0.00937677) / 0.18)*0.2471896) + 0.385537:(((x+
0.00937677) / 0.18) + 0.04378604) * 0.9661776
Where 0.0106232 comes from solving the second part of the equation using the
threshold value (0.1496582)
(0.149658 / 0.9661776 -
Thanks Ivan and Donat... this is great help.

While we're on the subject of digital motion picture cameras and
colorspaces that they store data in, do any of you have any experience
working with the Phantom camera? I'm getting frames from the Phantom that
look desaturated and cyan, but I'm not sure
