How to Use a Green Screen in Photoshop

When your favorite movie character flies above the earth or jumps from the building, then the movie magic is captured on a studio sound platform, shots turn into a reliable composite, with another view of another green background Changes. In films and still pictures, this process takes advantage of color contrast between a theme and the background of the fabric or the painted wall. An impact artist separates the foreground and makes the final scene. With the careful use of Adobe Photoshop's tools and features, you can do the same digital magic on your images.

step 1
Open the "Layers" menu, and then select "Duplicate Layer" to make a copy of your master image. This protects your original photo from any of the destructive steps involved in removing the subject from your green screen background.

step 2
Open the "Select" menu, and then select "Color Limit". When the color range dialog box opens, set the "Select" drop-down menu on "Sample Color". This setting enables you to use the Color Range cursor as the exact version of the Magic Wand tool and to select the background tone.

step 3
Activate the "Select" radio button below the image preview area so that the preview can show your selection results. Set the "Preview Preview" drop-down menu in your choice of preview option: Grayscale presents fully selected fields in gray in white and partial selections; Black Matt and White Matt use colors in their names to designate the selected areas, and Quick Mask presents the same preview that appears in the quick mask mode.

step 4
Click on the background green tone to start your selection. You can make your selection in the main image window on the preview image in the back of the Color Range dialog box or in the dialog box.

Step 5
Photoshop is considered part of the selected area to adjust the color range "fuzziness" slider to increase or decrease the range of colors. Increase or decrease this setting in the same way as you use the Tolerance setting that increases or decreases the sensitivity of the Magic Wand tool.

Step 6
To add to your selection, click the "+" eyedropper button and sample additional color areas. If you accidentally add that area in which you do not want to include, then press "Ctrl-Z" to undo the last sample action or click on the "-" field with a sample area. When the background color is fully included in the range, click on the "OK" button to apply it and come back to the main image window with the active selection.

Step 7
Press "Shift-Ctrl-I" to reverse the selection so that it can attach the foreground topic instead of a green background. Open the "Select" menu, and then select "Refine Edge" or click the "Refine Edge" button in the Options bar. Reduce radius settings to adjust sharp contrast between your subject and background.

Step 8
Adjust the Edge Slider to smooth the selection perimeter and wings, and use the Contrast slider to work hard on the edge. The shift edge slider moves the selection inside or out. If you see green tilt around the edges of your object - generally because the photographer fails to keep it from a green screen at the right distance - the color of the pixel on the outer edges to activate the "Disconnected Colors" checkbox Activate topic to move.

Step 9
To create a new version of the image layer with your selection applied as a pixel mask, set the sophisticated edge "output to" drop-down menu to "new layer with layer mask". Make this option especially if you use the Decontaminate color option, which changes the image instead of changing the selection. Even though you have duplicated your image before starting the extraction process, this option helps to protect your work from accidental changes in the regular part of your mask-making routine.
