The Basic Steps

These are the basic steps for completing Extractions based on color or shape. Examples for applying each of these sets of steps as part of a specific example appears in the Comments section.

For shape-based extractions:

1. Open an image that you want to extract something from in Photoshop.

2. Choose a layer to extract from.

3. Be sure the Force Foreground box is unchecked.

4. Use the Highlighter (by default it is the first tool selected when you open the screen) to cover the entire edge and outline of what you want to extract. There are options for Smart Highlighting (hold down Option/Alt) and Erasing. Complete the highlighting of the edges by closing the circle, or completing the highlight area.

5. When highlighting the edge is complete, fill the center of the area with the Fill tool.

6. Preview the extraction by clicking the [PREVIEW] button.

7. Zoom in and look at the edges of the extraction. Touch up as desired using the Cleanup (C) and Edge Touchup (T) tools.

8. When you have completed the touchup, click the [OK] button to accept the changes.

For color-based extractions:

1. Open an image that you want to extract something from in Photoshop.

2. Choose a layer to extract from.

3. Be sure the Force Foreground box is checked.

4. Use the Highlighter (by default it is the first tool selected when you open the screen) to cover the entire area which you want to extract the selected color from.

5. Use the Eyedropper to select a color to base the extraction on.

6. Preview the extraction by clicking the [PREVIEW] button.

7. Zoom in and look at the edges of the extraction. Touch up as desired using the Cleanup (C) and Edge Touchup (T) tools.

8. When you have completed the touchup, click the [OK] button to accept the changes.

Accepting the changes will extract the element you see in the preview to the same layer (or Layer 0 if extracting on the background). The result will retain the transparency as seen in the preview; that is, completed extraction will eliminate what became transparent during the process of creating the extraction.
