Re: AgX in Corona
Great setup thanks. Works really nicely to achieve soft renders. I found that adding a Tone Curve is useful to bring back some contrast.

Re: AgX in Corona
or maybe compare this with AgX for more fair comparison (update to aces1.3):

Re: AgX in Corona
While they both have issues with blowout areas, from my perspective I like the AcesOT more than the AGXLuts. The AGX looks washed out to me, losing a lot of contrast. Maybe I'm just used to how modern phones adjust photos to look nice and punchy.

contrast is a secondary element here. AgX Appearance Punchy is just one of demo looks supplied by the author. you can make it as contrasty as you need it to be.

it is all about handling of hot saturated colours (Corona didn't even bother with updating acesot but I guess it's a different discussion)

acesot vs agx with matched contrast attached:

Re: AgX in Corona
Interesting results with AGX. Could you export the lut's for the other contrasts looks as well ?

thanks!

edit:
looks punchy and golden are based on AgX Base with power, slope, offset and saturation transforms. Base is created from logarithmic encoding Kraken with 1D lut supplied with original AgX ocio config: https://github.com/sobotka/AgX
