Photoshop Extract Dialog Panel

The Extract panel is actually a Mini-program, that you can
use from within Photoshop to isolate images from their
backgrounds. Complete with a subinterface, it measures
differences of the edge of an image by it’s brightness and
color content, then determines the best way to isolate the

The basic technique is to use the Edge Highlighter tool to
draw a highlight border along the images edge, then fill it’s
interior using the Fill tool and Preview it.
You may refine and preview as often as you wish, until the
image has been successfully removed from it’s background.
You then extract it.
Important Note: You should always duplicate the image prior to using this panel. In this way, you will always keep the original intact.

Choose a color to use for the interior fill. A good contrasting color to the highlight choice makes viewing easier.
Smart Highlighting
This option is a powerful one! It helps keep the highlighting on the edge. Use when the foreground and background edge colors are similar to one another. You can toggle the Smart Highlighting on and off while dragging by pressing the (Ctrl) key. Smart Highlighting puts a minimum amount of paint necessary to cover the edge.
The Smooth setting helps with removal of stray artifacts in the extraction. You can enter a value or click the down arrow to access the Smooth slider. The higher the number entered, the greater the number of pixels will be affected. Edit, then click Preview to view the edited extraction.
