ACES & Photoshop friendly workflows

Hi there, just wanted to share with you an ACES workflow we came with at ENSI school in France.

You will need two plug-ins to make it work:

OCIO for photshop
exr-io

1- In Guerilla, we do an ACEScg render of a skylight. (viewer in REC.709 ACES)

2- Then you import this ACEScg exr linear render in Photoshop:

This box will show up if you have installed the plug-in exr-io. Just click ‘open’.

3- The render will show like this, due to srgb icc profile in photoshop.

4- Then we apply an ACEScg Ocio profile to the render with the ocio plugin.

It will look like this:

5- Then we convert the render to 16bits. So ,we can paint and have access to paint tools.

The render should not change at all.

6- After this, I will create a ‘levels’ adjustment layer with 0,45 value to undo the srgb icc profile of Photoshop.


The render looks exactly like in Guerilla (except to the slight difference between srgb icc and gamma correction)

7- Then we save the exr file with exr-io.

8- Finally we can import it in Nuke as ‘Output - Rec.709’ to make it match the ACEScg exr render originally from Guerilla.

9- You will just need to write as an ACEScg exr to finish the workflow and use the exr as an envlight.

I hope that makes sense and I would be curious to know what you guys think about this setup.

Many thanks,

Chris and Quentin
