Join Mark Lefitz for an in-depth discussion in this video Adding a gamma correction in Nuke, part of Photorealistic Lighting with Maya and Nuke.
The rendered image in Nuke looks bright and washed out, if you've noticed, when…I've opened up Nuke, and brought in our car EXR file.…That's because linear images from programs like Maya, and other 3D packages, do…not take into account the gamma curve attributed to the monitor.…And we can take a look here at what that monitor gamma curve actually looks like.…So, if we go back into Maya here real quick, and I've rendered out what our latest…car render looks like, with all its lighting, and its HDRI, it actually looks good.…That's what I like, because when I'm working, I want what my final output is to…look like here in Maya.…
So, Maya actually applies an sRGB gamma correction under the hood for this render…view, so it's going to be in the right color space.…Unfortunately, Nuke does not apply that same gamma correction.…Let's go back to Nuke here.…So, we can see that it's still washed out, and bright.…Well, we can make some adjustments in Maya, so the image will have an sRGB gamma…correction, but that requires changing all the textures and the colors to Linear,…
