Cover or spotlight part of a document-camera page

Use a mask in VeeCam to hide a region of the page or to spotlight the part you are explaining.

A mask hides a region or spotlights one part of the page under the camera. It does not arrange several pages. Tiles do that.

Place the mask

Show the page on the live view, or open it in a tile.
Add a mask over the region you are not discussing, or spotlight the region you are.
Move the mask when you move to the next paragraph.

The paper itself is unchanged. The mask is only on the Mac’s view of it.
