Using color levels adjustment+linear exposure control vs. exponential

[jpmartin]

If I render using linear exposure control, and then adjust the color levels control in the VFB to compensate for overexposed areas (bring the white slider up to something larger then 1), will that give me the same/similar effect as rendering using exponential?

It seems like this could be a good solution with a little more control over exposure since we can adjust the levels in the VFB post-render, but i'm not 100% sure since it seems like this control effects the diffuse map as well, where the exponential exposure control seems to only affect the direct and indirect illumination channels (right?)

Thanks!

Yes, it will give you a very similar result.

No, we don't apply the color correction only to the direct and indirect channels; it is applied over the final pixel values.

Always quick to respond! Thanks, Vlado!
