Exploring powerful nodes
We will now introduce some new nodes to give us a better idea of just how powerful and versatile the node system is. This will give us a good foundation for creating high-quality materials by showing us which tools we have available to us. We will use the color grid image that we generated previously to demonstrate how other nodes work.
Color control nodes
We can use nodes to adjust the colors of image textures in Blender. To do this, we will learn about the Hue Saturation Value node and the Bright/Contrast node. These two nodes will help us to quickly adjust the brightness, contrast, hue, saturation, and value properties of an image without using an external image editing program. In the next few steps, we will learn to use the Hue Saturation Value node:
- With Shift + A, add a Hue Saturation Value node from the Color section.
