I am having trouble understanding how to get Karma to output my Aces conversion. I use Redshift and I can export the image exactly how I see it in my viewport with all transforms baked in with export LUT toggle.

I understand after I export I can bring it into another program and change gamma. However I just would like to export my image how I see it in the rendered Karma viewport.

How do I go about this?

It's not possible. A separate program must be used. Houdini does come with a command line tool though -- hoiiotool

Use the command as such to convert color space to a display/view:

hoiiotool -i input.exr --iscolorspace "in space name" --ociodisplay "display name" "view name" -o output.png
replace "in space name" with your color space name, such as "ACES - ACEScg"
replace "display name" with your display, in your screenshot it is "ACES"
replace "view name" with the desired view name, based on your screenshot "sRGB"

You can even burn-in the brightness tweak with --mulc

hoiiotool -i input.exr --mulc 1.8 --iscolorspace "ACES - ACEScg" --ociodisplay "ACES" "sRGB" -o output.jpg
