# Lut Class
 
Represents a look-up table (LUT) used for intensity transformation.
 
**Namespace:** [Aurigma.GraphicsMill.Transforms](https://www.graphicsmill.com/docs/gm/N_Aurigma_GraphicsMill_Transforms.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```csharp
public sealed class Lut : IDisposable
```
 
## Remarks
  
Look-up tables are used in most tone correction algorithms. LUT defines a "luminosity function", in other words, a rule which translate channel luminosity to another value. This class defines this function as an array of points and interpolation algorithm.
