GAIN
THE BOX'S MAIN HELP:
If X is less than 0.5, the output is twice X raised to log(1-GAIN)/log(0.5) divided by 2; otherwise the output is 2 minus twice X raised to log(1-GAIN)/log(0.5), divided by 2 and subtracted from 1. Basically a fancy contrast function.
GAIN (input):
This value must be a float. This is the gain.
X (input):
This value must be a float.
OUT (output):
If X is less than 0.5, the output is twice X raised to log(1-GAIN)/log(0.5) divided by 2; otherwise the output is 2 minus twice X raised to log(1-GAIN)/log(0.5), divided by 2 and subtracted from 1. Basically a fancy contrast function.
