When I render with Karma, the TIF file is too bright, compared to the viewport?

How can I adjust the file output to match viewport?

ANSWER: For now, render to JPG. Karma renders JPG files using the 2.2 gamma.

When I render to TIF (or EXR), I get the same color space as when I render to the viewport (at least with mplay). Are you rendering to 8-bit TIF images or float?

In the Karma LOP, there's an OCIO image filter you can use to specify a color transform if you want to convert to a specific color space before saving to disk.

I don't see any options at all, from the Karma node, when choose TIF sequence. Where would I specify 8-bit in LOPS? H18.0.416.
