-'''Node Description & Purpose: '''<br /> The Clamp family of nodes allow you to clamp, or restrict, the values of the colour or scalar coming into the Input between the values specified by the '''Min''' input and the '''Max''' input. If the value is less than the '''Min''' value it's set to the '''Min''' value. If the value is greater than the '''Max''' value it's set to the '''Max''' value. The clamping is done component-wise for colours. Here is an example using a colour, with the following values:

 After clamping the colour will have these values:
-'''Node Type: ''' Function
+In the example below, an EXR image containing vector data is assigned to the Main Input of the Clamp Colour node.  Visually, the green pixels represent data above a value of 0 in the Y axis, whereas the magenta pixels indicate a blend of positive and negative values lying on the X and Z axis.  When enabled, the Clamp Colour node outputs all values below the Min value as the Min value, and all values greater than the Max value as the Max value.
