Brightness difference between Viewport and Render

[chafouin]

Hi there,

I'm noticing a difference between the viewport and the final render.

I am not using clamping, there is nothing done in Compositing, so I'm not sure why it looks like it's clamping or applying a different tonemap.\
I attached the scene.

Are both running on the same mode ?

CPU
or
GPU

CPU and OpenCL, I tried both.

You are using a negative scale and that is the source of the problem, as work around, you can apply all transformation to the object and it should fix the problem.

I have the same problem,best seen in the shadows,
top image is render
down is preview
same settings for both
how to make final render to look like preview render in my case?, it is not just brightness or curve problem
I want to know because overall preview looks much better than render for me

Thanks Dade!
