- To exit the mask editing mode (for example, you may want to adjust the settings of the filter itself), de-activate the filter mask by clicking the smart object's thumbnail in the Layers palette. The white "dashes" disappear.
- To continue editing the filter mask, you re-activate it by double-clicking the "Reveal Filter" thumbnail in the Effects palette.
Important! In case your smart object has 2 or 3 smart filters, the mask hides all of them. Masking individual filters is not possible.
Alternatively, you may use the "Hide All" approach to filter masking:
- In the Effects palette, double-click the "Hide Filter" thumbnail. It activates the filter mask and fills it with black color. As result, the smart filter is completely hidden.
- Paint with white color there, where you wish to reveal the filter effect.
Sometimes, it is more convenient to create a mask from an active selection.
- That is, you make a selection, for example with the Polygonal Lasso tool.
- Then use either the "Filter Selected" or the "Unfilter Selected" action (screenshot 2).
Tip. Although the filter mask thumbnail is invisible in Elements, you can display a mask shape in the document window as a color overlay (screenshot 3). If you still find this method inconvenient, consider alternative masking.
The white "dashes" around the smart object's thumbnail mean that a filter mask is currently active and you can edit it.
