Images with Alpha look different when layered in compositor compared to Photoshop I'm struggling to get the same result in the Blender node editor when layering images with transparency, to the result I get when doing the same in Photoshop.
The Blender result is shinier/washed out compared to the result from Photoshop (see below).
The blend file can be found here:

I've played around with Premultiplied and Straight Alpha, tried 32 bit pngs, mix nodes and Alpha Over nodes, and pulling out my hair, but haven't been able to find the answer.

Thanks for any help!

Photoshop has a non-linear reference space typically, and as such, all blends are wrong.

Blender's compositor on the other hand, uses a strictly linearized reference space, and alpha overs, assuming you are using associated alpha and the Alpha over node, are correct.

Nonlinear Over:


Linearized Over:
