    Step-by-Step How To Blur Background Detail in Photoshop Elements

    How to blur background detail in Photoshop Elements: Step 1

    01 Open the start file
    Launch Photoshop Elements, then go to File>Open. Browse to your start image and click Open. The raw shot will open in the Adobe Camera Raw editor. Press O to see any over-exposed areas as red patches.

    02 Clobber clipping
    Drag the Recovery slider up to 35. The clipping warning patches will disappear, restoring detail to the over-exposed areas while leaving correctly exposed tones unaltered. Set Vibrance to +40 to boost colours without over-saturating skin tones.
