2. Press "D" to reset the forground and background colors

4. Now we need to invert the image. Press CTRL I to invert or go to Image > Adjustments > Invert . Now go to Image > Adjustments > Levels or ctrl L and use these settings
5. Now the fun part. Go to Filter>Distort>Wave and use these settings. These settings can be played with so experiment
