Photoshop Extract Dialog Panel

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
area.

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.
The Tools
Edge Highlighter tool
Use this tool to define the edges of the area you want to keep. Drag this marker and highlight the edges of the image you wish to extract.
Fill tool
Use this tool to fill the area inside the area outlined by the Edge Highlighter. Click the Preview button afterwards to preview the quality of the extraction.
Eraser tool
This tool becomes available once a highlight has been drawn. Use to remove areas of a highlight or unwanted pixels.
Eyedropper tool
This tool is activated by selecting the Force Foreground box. It allows you to set the color of the image you wish to keep.
Clean-up tool
The Clean-up tool subtracts opacity. It becomes available after the Preview button has been clicked. Multiple passes with this tool has a cumulative effect. (Option+Alt) while painting will restore opacity.
Edge Touch-up tool
This tool is used to edit the extraction boundries. It sharpens the edges of the extracted image. This tool is available once you are in Preview mode. The tool has a cumulative effect. If the edge is a troublesome one to define, it adds opacity to the image or makes the background more transparent.
Zoom tool
This tool is used to enlarge image on screen. Simply, select and click on image to enlarge. Comes in handy when the image is small or the image borders are hard to find. (Alt+Click) to reduce image size.
