Exp colour

The Exp family of nodes output the exponential value of the Input value. The exponential value is the mathematical constant e raised to the power of the Input value i.e. e to the power of Input. e has a value of approximately 2.7182818.

 

For colours the calculation is done on a component-wise basis, for example:

 

Output.red = e to the power of Input.red

Output.green = e to the power of Input.green

Output.blue = e to the power of Input.blue
