There are 5 modes available
1 - Bright Glows
2 - Bright & Dark Glows
3 - LightWrap
4 - Merge Under
5 - Output only Bright Pass
-1- Performs simple Bright Glows but with some handy parameters.
- First use "view threshold" tickbox to finetune from which luminance the glow shines.
- "Soft Mix" : mix between Screen and Plus blend.
- "Post Gain" : Used to boost the effect but it can also be used to add a global tint.
- "Thin Glow" : Usually 2 glows gives better results. (because the light behaves not linearly)
So the main one is a big one and the second is a thin one.
-2- Enables Dark Glows with some same parameters as the Bright ones.
- There are extra options to avoid that the darks darken the super brights. (Because it hasn't to)
-3- Performs a LightWrap with all Brights Glows options available (2 different size glows, threshold options)
- Of course it has sense only for RGBA sources, and assume to be premultiplied
- The input "glow_source" has to be connected to the background plate (which will be comped under)
-4- Same as -1- but the glow is comped under the source.
- So the source must have an alpha, and is assumed to be premultiplied.
-5- Same as -1- but the glow is NOT comped on the source.
- All inputs are optionals except SOURCE of course.
- "Brights Mask" allow to restrict the brights glow source areas. It is not masking, which is quiet useless.
- "Darks Mask" i think you've understood ...
- "Glow Source" allow to choose an alternate image to generate the glow. Especially for the LightWrap but for example you can use a quick comp as" Glow_Source" and then processing brightGlow and darkGlow on a RGBA source.
