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
Vari-Star filter applied. The Magnifier will accurately represent what the Vari-
Star filter will look like when applied to the full size image.
4 If the Parameters window is not showing, click the Parameters tab at the bottom
of the Presets window.
5 Adjust the Star > Brightness, Spokes, Size and Color settings to your liking.
In some of the filters, a selection is generated to create the desired effect--in
this case, star effects.
6 Change your View to Selection to see the selection values.
The areas that are white in the selection are the areas where stars will be
introduced. The location of the stars within the scene can be adjusted by
modifying the Selection > Position and Selection > Range parameters.
7 Change the Selection > Position parameter if you want to select different values
to be used for the selection.
8 Change your View to Stars to see the generated stars.
9 Increase the Selection > Range control to add more values to the selection.
Decrease for less values.
The Selection > Range parameter has been purposely set to a low value. A
high range setting will slow down the filter significantly.
10 In addition to Selection > Range, you can also raise the Threshold value to limit
the amount of stars.
