The Hue/Saturation Channels .8bf Plugin


Hue/Saturation Channels is a utilitarian filter intended to assist in the selection or masking process.

• Unlike hue, which wraps around a starting point, hue difference prevents the splitting of closely-spaced hues into black and white.

• Rotate rotates the hues, and moves the point from which hue and saturation difference are calculated.  This can help isolate certain hues, or areas of intermediate saturation.

• Auto levels is applied by default to maximize the value separation.

Works with 8- or 16-bit RGB images.

The unregistered filters will save images up to 720 pixels in width and/or height.  Please purchase a registration key for $9.00 which unlocks all of the RC Filters.  Use the PayPal link below and I will e-mail you a text file (RCFKey.txt) to copy into your plugins folder.  Be sure to use a valid e-mail address (I don’t sell or give them away).  If you previously paid for any of the RC Filters, message me and I will send you a registration key.  The filters come with a demo key; if properly installed, the dialog will say “Demo key” when you click the About button.

The filters, the help files, and the registration key all go into the same folder.  It may help to make an RC Filters subfolder.  Each filter has a link back to the plugin folder on the About dialog for easy access.
