[ARNOLD - MAYA] Exported image with transparency problem

Worldevour

I render my images with nothing in the background so I can put whatever I want afterwards in photoshop. I use depth of field so my model gets blurred. This blue background in the arnold renderview is just a color I choose in the arnold renderview settings. I put the same color in photoshop and this dark outline appears. I tried almost every image type.
Is there a way to fix this?

Use EXR to export your images.
And this plugin does also help with a lot of PS issues.

Render  Cryptomatte . It was invented for exactly this kind of issues.       You could use it then in any 2d composer  or  in  free Blender  compositing tab  ( search for cryptomatte node there)    and   beauty AOV on a black background   divided by 32 bit mask (un-premultiplying process)  or if still not working  re-composited back  properly from a set of basic AOVs  to  produse  regular  kind of png/tiffs.

 

It's perfectly possible to get good alpha without color bleeding
