# Sharpening a Key Source Image

Sharpen a key source image to increase or decrease the softness of only the pixels that are within the chrominance and luminance range for tolerance.

NoteThis procedure applies to the Diamond Keyer only.

To sharpen a key:

1. View the secondary in the Player. Press F11 to toggle between Matte view and Secondary view.
2. Drag the Sharpness slider to adjust softness and reduce noise if the matte appears grainy.
