translating negative values to positive
I am trying to create an expression slider which when increased simultaneously blows out the luminance values while desaturating the video. I’ve easily attached the glow parameter but when using Hue & Saturation the desaturation value is in the opposite direction (negative value)
what expression do I need so the value works when the slider moves up in positive values?

Just put a minus sign in front of the slider value, like this:
slider = -thisComp.layer(“Null 1”).effect(“Slider Control”)(“Slider”).value;
(or multiply it by -1)
