Viewport render and final render don't match brightness#356354

Hi all,
I have experienced a few times that my final render ended up being darker compared to the viewport render.
Does anyone know why or when this can happen?
Any help is greatly appreciated.

Thanks,

Giuseppe

One of those moments where we can see one of them is darker than another. Screenshots of viewport and final render side by side. Preferably PNG encoded.

Hi Tom,
here is the image with both renders.
I know it is small and cropped but I think one can see that the viewport render is brighter compared to the final render.

Thanks for your time.

Do you mean when you have exported it? I have noticed differences in image when I have exported the images to jpeg, what ever it is it seems like a difference in response curve, I'm not an expert on this but the image will appear slightly different in different programs e.g 3dsmax, maxwell, photoshop unless they have exactly the same colour space and gamma settings.
I would bet it is a difference in gamma, rather than exposure

Is cornell scene doing the same problem there?

As seen below, it's OK here...

I agree to bograt.
if u use gamma setting of 3ds Max, just turn off.

Thanks for all the feedback.
I will try the cornell scene first and go from there.
I am an Alias user and export my 3D as obj into Maxwell Studio so whatever the gamma setting is in Mx Studio I haven't touched it.
Bograt, sandykoufax and le13emepanda, thanks for the suggestions and feedback.
Appreciated.

Hi Tom,
It seems fine in the cornell scene.
What do you suggest?

It means the difference comes from the scene somehow. Could you send me the scene so I can check? tom at nextlimit dot com
