P: Enable more features including tools, Curves and other Adjustments for 32bits/channels image

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.

Why in Photoshop the 32 bits/channel has so many limitations ?

its been years and years why this hasn't been addressed  yet

Image is not available

like all these important adjustments grayed out this images also blending modes etc

 

while a program like after effects which is also from the adobe family works like charm

 

any good news plz

I like to see curve (adjustment layer) implemented under 32 bit mode. This would make it possible to make my own tone remaping and enable me to see the image naturally while working on it in this mode.
You would need to adjust the tool for linear float ranges.

No sir, with a 32bit/channel image level command is available, not curves.

I would expect so, since it is possible in Photoshop CS5.

Thanks for the request. We can't comment on future versions of Photoshop at this time. Sorry.
