Black Diffusion/FX® / Gold Diffusion/FX®
Gives a silky-smooth look to textured surfaces, suppresses facial blemishes
and wrinkles, while maintaining a clear, focused image. Creates a diffused
image that doesn't look like it's been shot through a filter. Gold Diffusion/FX®
infuses special warmth by adding a soft, golden tint to shadows.
1 Apply Black Diffusion/FX® or Gold Diffusion/FX® from the HFX Diffusion
category.
2 Select the Magnifier tool in the Viewer.

When the Magnifier is selected, a portion of the image is displayed at a 1:1 pixel
ratio in the Magnifier window and shows the actual pixels of the image with the
Diffusion/FX® filter applied. The Magnifier will accurately represent what the
Diffusion/FX® filter will look like when applied to the full size image.
3 Try out some of the presets.
4 If the Parameters window is not showing, click the Parameters tab at the bottom
of the Presets window.
5 Change your View to Selection to see the selection values.
In some of the filters, a selection is generated to create the desired effect--in
this case, smoothing of image details.
The idea here is to generate a selection that isolates the areas of the image that
need to be smoothed. For instance, you might be trying to isolate and smooth
the skin on a person’s face. The white areas of the selection are the areas that
will be smoothed. The selection has been preset to a midtone selection. This
can be modified by using Selection > Position to select the luminance value and
Selection > Range to select the amount of values to be used for the selection.
6 If needed, change the Selection > Position parameter so that the image areas you
are trying to smooth are as white as possible in the selection.
7 Adjust the Selection > Range value so that the white values of the selection are
limited as much as possible to the image areas that you are trying to isolate.
