Photoshop needs to implement a linear workflow, not only a 32 bit mode where 5 things work. a fully linear workflow where u can import an exr, work on it. and export it. for me to actually make this work, you have to do a bunch of workarounds. Adobe needs to catch up with the rest of world. I dont want to stop using photoshop, because i like it. but its difficult, especially when you work in the movie/commercial business. you cant have clamped values. its hard not to start looking at other appliacations like Affinity, that do indeed have linear workflow.

Could you describe step by step what you exactly do with .exr files you need a woraround for these tasks. That may be not ever happen Adobe will implement that you ask, as they surely don't follow single request. There may be way to solve it with scripting that will make whole process very smooth.

i have to import the files into Nuke, change the colorspace from linear to some sort of Log, Slog for example. that sets the value from going above 1, to 0 to 1. it looks quite flat then.but i render that OUT as a linear exr. even tho it looks like Slog.  i import that into photoshop, as an exr. i then set the mode from 32 bit to 16 bit. to actually be able to use tools in photoshop. after im done. i have to set the mode back to 32 bit in photoshop. u also have to download open exr plugin to render the exr back out. u then import that into nuke. and reverse the process. 

if photoshop just was linear. u can import an exr. it looks the same, do ur stuff. export out. boom done.

I agree. After Effects seems to handle 32bit files a bit better. It also seems to have more options for adjustments such as Curves layers. OCIO transform layers can be added/used in 32bit also, allowing for ACES workflows to be used. I think unbounded ICC profiles may allow this as well, however Photoshop doesn't have the option for OCIO adjustment layers or Color Space Transform layers. 

I know Lars Borg from Adobe was working on something with this. https://groups.google.com/d/msg/ocio-dev/AnmLVkv1Tcg/RgEDd9oIBgAJ

Plus better compatibility with Adobe products was mentioned in the ACES: Retrospective and Enhancements. https://www.researchgate.net/publication/314385826_ACES_-_Retrospective_and_Enhancements_-_2017

I think maybe a workspace/option/configuration could be added for Photoshop that works better for people that work in VFX, 3D, Matte Painting, Compositing, Cinema, etc. Have it work in 32bit bit, add OCIO, bypass/handle color management manually, Logarithmic Gamma working space and tools for working with cinema footage, film scans, etc.  ACES integration. Would love an upgrade to the "Blend if" sliders. Maybe replace it with an HSL qualifier like Davinci Resolve.
