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.

Hi and thank you for this gizmo, I'm testing it to magnify some hologram works and it works perfectly. I would like to have some noise or pertubation effects but it's already a pretty good thing.

Hi,
Thanks for the kind words. For some noise and perturbation you should take look at iblur_hub that has some noise effects to mimic glint.
cheers,

You totally rock! And I don't have to convert it to a group.
