[Tig] Is there anybody out there - linear light processing again

[glenn chan]

Deanan,

I'd be curious as to why you think "correcting in HDR directly is not a
great idea".  The topic was discussed a while back as I was one of the
advocates for the use of linear light processing.

A quick summary on how linear light processing is different:

Processed in native gamma (sRGB because this was a digital still photo)

Processed in linear light (ok, an approximation of it)

In both images, "saturation" was increased 2x.

An of course, linear light processing offers visual differences in cross
dissolves (more like film/optical dissolves), blurs, and compositing also.
I'd be curious about arguments not to use linear light processing (because
I'm curious, and could be wrong).
