On: Fun with in-engine color grading

This is very clever.

I've used exported curves from photoshop to generate color correction LUTs, but actually just displaying the LUT in the screenshot, and then using the manipulated result to generate back a new LUT is much more flexible and pretty smart!

It’s a pretty common trick.

See e.g. section 24.2.3 here: http://http.developer.nvidia.com/GPUGems2/gpugems2_chapter24...
