I’ve been using ACES in After Effects for a while, but mostly exporting VFX shots to ProRes outputs. I’m trying to export a comp from my ACEScg project to sRGB for use in Photoshop. I have tried all sorts of transforms and output settings but cannot find the correct way to get the white parts of the image to come out white. I have a background that is white(1,1,1) but it looks light gray in AE due to the gamma curves on display. Is there a way to properly export this to an image where that white layer comes out 255,255,255 in sRGB?
I think it depends a little bit on what you’re trying to achieve and how your are using ACES for your project. In isolation, 1.0 isn’t display white because the default working space is linear. After the ACES display transform a much higher range of linear input values are tonemapped into 0-1 to create a visually ‘pleasing’ image for scene referred input data like from cameras or CGI. If you want display based input colors in comp you can convert them back to the working space via an OCIO display effect set to invert.
But depending on your goal inside Photoshop which also supports OCIO btw, other strategies in either AE or PS could make more sense.
Could you tell a bit more about your specific context?
