- What is Linear workflow and Gamma correction tutorial HD
In this tutorial the guys from FlippedNormals.com will cover the topics of Linear workflow and Gamma correction.
We will take a look at why your renders might look dark and blown out, and how having a linear workflow will help you avoid washed out textures, giving the light in your scene more depth.
A linear workflow is necessary for photorealistic rendering because any output display (for example, a monitor) has a signature response curve that affects the way color is displayed. As a result, to produce color that appears correct to the human eye, a color correction has to be applied to an image. Therefore, you must reverse this color correction before lighting and rendering so that rendering calculations can be made with the correct color values, and then color correct the resulting image again before it is displayed, so that it appears correct. This results in much more realistic lighting and compositing with greater falloff and softer highlights, as illustrated in the image below.

That last slide of color correction pipeline what really awesome, It cleared up the confusion. Thank for the tutorial.
AWESOME! Thanks! I think this is something that definitely needed to be addressed so I appreciate you opening this into a tutorial explaining this more in-depth...
Bless you cousin.....This helped...Wish you success in your future endeavors.
Perfect, i finally get it lol.
VERY Good video :)
What do u mean by "linearize" :)
Thank you for trying, but I still don't understand any of this colour management..
you have it wrong here, output should be left and input should be at the bottom.
the bottom curve is sRGB 2.2
Hi I saved single frame PNG，it looked just like how it looked in render picture viewer, but when I saved PNG sequence, it appeared very dark! It's also very dark when saved as MP4 or AVI. How to fix that? I tried gamma 0.454,1 OR 2.2, all dark when saved PNG sequence or videos!!! Thank you!
Yeah linear is really scary. Simple switching from gamma to linear in Unity made a huge scare away from it.
Using default objects and materials, I switched to linear. Gamma looked smoother while changing to linear made it almost stale with no softened shadows.
The scene becomes much brighter and doesn't look right directly so you have to mess around with the light settings to get it right
