# Brightness.Auto Property 
 
Gets or sets a value indicating whether the transform should be run in automatic mode.
 
**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 bool Auto { get; set; }
```
 
### Property Value
 `true` if the brightness is automatic; otherwise, `false`.
 
## Remarks
  
**Note** 
If you set Auto property to `true`, and modifying [Amount](https://www.graphicsmill.com/docs/gm/P_Aurigma_GraphicsMill_Transforms_Brightness_Amount.htm.md), Auto is reset to `false`.
 
When you create the [Brightness](https://www.graphicsmill.com/docs/gm/T_Aurigma_GraphicsMill_Transforms_Brightness.htm.md) without specifying brightness amount, default value is `true`. If amount is passed to constructor, default value is `false`.
