Normals is a render channel that stores the camera space normal map using the geometry's surface normals. The Normals Render Channel is useful for adjusting the lighting in the composite. For example, the red, green, and blue channels can be adjusted in compositing software.

Bump maps are not represented in this render channel; to include bump maps, use the Bump Normals Render Channel.

When the Normals Render Channel is saved as a separate render channel, its output value is kept between [0;1] range; if saved as a multichannel .exr, its output value is from -1 to 1.
