ASC CDL

<h2 id="combined-function">Combined Function</h2>
<p>The formula for ASC CDL color correction is:
</p>

o
        u
        t
        =
        (
        i
        ×
        s
        +
        o
        
          )
          
            p
          
        
        
      
    
    {\displaystyle out=(i\times s+o)^{p}\,}

<p>where
</p>

o
        u
        t
      
    
    {\displaystyle out}
  
 is the color graded pixel code value

i
      
    
    {\displaystyle i}
  
 is the input pixel code value (0=black, 1=white)

s
      
    
    {\displaystyle s}
  
 is slope (any number 0 or greater, nominal value is 1.0)

o
      
    
    {\displaystyle o}
  
 is offset (any number, nominal value is 0)

p
      
    
    {\displaystyle p}
  
 is power (any number greater than 0, nominal value is 1.0)
<p>The formula is applied to the three color values for each pixel using the corresponding slope, offset, and power numbers for each color channel.
