Simple Color Correction

WonderLookPro v3.2 implemented Simple Color Correction.

On this mode, you can correct color by color ballance, exposure lebel, saturation and gamma, which are basic parameters of color reproduction.

If the system can use IDT by the setting of LUTs, this correction is performed on ACES linear color space, so the color correction result is very similar with the camera operation, like lens setting or filter work.

We added Knee control (highlight mapping) on V3.4.

①Color Balance Correction

This is for color balance correction. The effect is equivalent to the color filters on the lens. But this correction keeps brightness so it won't be darker.

Color Temperature is automatically calculated and shown on the spinbox at the bottom of 3.

When it has focus, up/down/left/right key is effective. q/a keys are  for Red, w/s keys are for Green, e/d keys are for Blue correction.

②Exposure Level Correction

This is for exposure level control. Parameters are shown in EV unit.It's equivalent to the iris control of camera lens.

When it has focus, up/down key is effective.

r/f keys are always usable for increase/decrease this parameter.

③Color Temperature Correction

This is for color balance correction by color temperature parameters. "Color Temp." slide bar corrects color balance  in parallel direction of color temperature.

Default value is 6000K.

"duv" slide bar corrects color balance in perpendicular direction of color temperature. Default value is 0.

When it has focus, up/down key is effective.

t/g keys are always usable for increase/decrease color temperature parameter.

y/h keys are always usable for increase/decrease color temperature duv parameter.

④Saturation control

This is for color saturation control.

When it has focus, up/down key is effective.

y/h keys are always usable for increase/decrease saturation parameter.

⑤Tone Control

This is for linear tone control while keeping the brightness of 18% gray point.

When it has focus, up/down key is effective.

i/k keys are always usable for increase/decrease tone parameter.

　⑥Knee Control (V3.4)

It can control the curve around highlight. You can set the position of the highlight by controlling "Position Control", which can be set in nits.

"Knee Value" controls the level of the curve. You can not only soften the curve but also harden the curve.
