Why to work in Linear?

[Diurno]

Hi all, after the suggestion of Rork in my other discussion, i started to try to work always with a linear workflow; but i've noticed that the linear workflow wash out all colors in my scene, and if in some situation althought this i've a good result; on othes i don't see any advantage to use it....
in other words: why and in what situation is good to work with a linear workflow?

The point in linear colourspace is that mathematically it is being computed linearly. Things add together correctly, instead of being added together where darks are too dark and lights are too blown out. The reason some of your stuff looks too washed out is because you're probably using old settings that would work in a weird gamma setting, but now with proper (non tweaked to hell) values, appear with less contrast.

Here is an article on it explaining in more in depth: http://www.xsi-blog.com/archives/133

There's an odd bug in SI, where sometimes the scene will somehow not 'release' previous gamma settings from the preferences, and start adding up gamma in the renders.

If you have set your preferences in an existing scene back to linear workflow, and still see overblown/washed out renders, try merging that scene into a fresh one and see what happens.
Or create a model of the scene and import that into a new scene to start from scratch on the scene's gamma values.

I've been bitten by this one in the past a couple of times, and it's very difficult to repo so I cannot tell you why this happens.
