possibilities with SilverOxide Filters:
All the filters work within selections.
Draw a selection in the middle of a picture, invoke the filter and
you can have BW in the middle of color, or reverse the selection and
have color in the middle and BW around the outside. Or select a color,
invert the selection and have a single color in a BW image.
Note: When the filter
is invoked, the image in the preview is the total image, not just
All the 16 bit filters
work with CS and 8 bit or 16 bit layers. This allows you to create
a range of color effects by copying a layer, doing a BW conversion
on it and then using the opacity to change the color rendering below
it. This allows you to render the colors based on the conversion
luminosity of the color. This gives it nearly a color wash effect.
The 8 bit filters work
on the 8 bit layers, allowing the same creativity in the 8 bit domain.
