Need to Know : 

As it currently stands only Nuke & Fusion can add post color corrections (also know as Tone Mapping) correctly. Photoshop and After Effects require addition plug-ins. This means if you are doing Animations you can keep your animation/Image Linear, if your doing stills you will need to save your correction out of the V-Ray Frame buffer or use separate render channels option in Vray (this will save/bake your correction) but you are saving the highlight burn into the file.Here are some plugin you can upgrade Photoshop & After Effects.

Expressions, Change the BurnAmount to a number between 0-1
r*(1+r*(BurnAmount**2))/(1+r)
g*(1+g*(BurnAmount**2))/(1+g)
b*(1+b*(BurnAmount**2))/(1+b)
