Advanced Options

Figure 15.193. Advanced options of the “Filterpack” filter

These advanced options let you work more precisely on the changes applied to the image and on the preview size.

Preview Size

Something like a zoom on previews. Normal size is 80.

	Tip
	In spite of Preview Size option, this size is often too small. You can compensate this by working on an enlarged selection, for instance a face on a photo. Then, you invert selection to work on the other part of the image.

Affected range

Here, you can set the tone range that the filter will affect.

The curve in this window represents the importance of the changes applied to the image. The aspect of this curve depends on the Affected range you have selected: Shadows, Midtons or Highlights. You can set the curve amplitude by using the Roughness slider in the main window of the filter.

By using the available controls (slider and triangles), you can precisely set the form of this action curve.
