Selective masking
Rather than apply a filter to uniformly change the appearance of your picture,
you can change only selected regions instead. PhotoLab lets you mask picture
areas by painting areas to be either affected by filters or simply left alone.
To apply a mask:
1. From the Mask drop-down menu, select New Mask.
2. In the Tool Settings pane, select the Add Region tool to allow
you to mask regions by painting.
3. Adjust the settings to suit requirements, especially adjusting Brush
Size to paint larger or more intricate regions.
Change the Mode drop-down menu from Select to Protect to
protect painted regions from masking (i.e., the inverse of the Add
Region option).
