Removing solid background from image

You’ll need: image file with solid background color, Photoshop (in my case CS5)

  1. Select “Color Range…” from the “Select” menu
  2. In “Color Range” dialog box, click on the eyedropper tool, drag the “Fuzziness” slider to about 30, check the “Invert” checkbox, choose “Grayscale” from the “Selection Preview” popup and make sure the “Selection” radio button is pressed
  3. With the eyedropper tool, click on the color area of the image you would like to remove  (either on the main canvas or in the “Color Range” dialog. Area with solid color is displayed  as white, and the rest of the image (which will be selected) black
  4. Click “OK”
  5. Select inverse and delete unwanted part of the image
