Using The Fade Command

Did you know after you've applied a filter, used a tool such as the Brush, Blur or Dodge tools or used an adjustment command like Levels, you can use the fade command to reduce the effect. After using any of these techniques, look under the Edit menu for the Fade command – it will say "Fade Gaussian Blur", "Fade Brush Tool", "Fade Levels", etc. Drag the slider to gradually fade out the effects of the last step you just did – undo using a slider!
