Hi guys!
I usually don't work with backplates and I'm finding out some problems with a test I'm working on.
As you can see in the attached images there are many differences between saving a png and composite it in photoshop (the car of course is rendered) and rendering a 3d object straight onto a backplate.
Basically the image on the left has the right amount of shadows while the whole plate is affected by my tone mapping setup (and even reflections/refractions are odd), the image on the right is all good (including reflections and stuff) but the shadow is so dark.
How can I get the shadows that I have on the left even on the right image?
Thank you guys

Not sure how you're comping them but one problem is that when you're working in anything else than 32bits and multiplying shadows, multiply is a subtractive mode, meaning it only subtracts values (darkening) but not adding any values (GI lighting). I just throw an adjustment layer on top of the shadow (levels for example) and increase mid-tones, this mostly helps.

I am not100% sure, but it looks like the issue from this thread: https://forum.corona-renderer.com/index.php?topic=18936.0

Yep looks like the same thing, I will do some tests with 32 bits exr and maybe I will try some small tweaks on the hdr gamma to make shadows darker/lighter
