Hide Smart Filters
❖ Do one of the following:
• To hide a single Smart Filter, click the eye icon next to the Smart Filter in the Layers panel. To show the Smart
Filter, click in the column again.
• To hide all Smart Filters applied to a Smart Object layer, click the eye icon next to the Smart Filters line in the
Layers panel. To show the Smart Filters, click in the column again.
Reorder, duplicate, or delete Smart Filters
You can reorder Smart Filters in the Layers panel, duplicate them, or delete Smart Filters if you no longer want to apply
them to a Smart Object.
Reorder Smart Filters
❖ In the Layers panel, drag a Smart Filter up or down in the list. (To reorder filters from the Filter Gallery, double-
click that word.)
Photoshop applies Smart Filters from the bottom up.
Duplicate Smart Filters
❖ In the Layers panel, Alt-drag (Windows) or Option-drag (Mac OS) the Smart Filter from one Smart Object to
another, or to a new location in the Smart Filters list.
Note: To duplicate all Smart Filters, Alt-drag (Windows) or Option-drag (Mac OS) the Smart Filters icon that appears
next to the Smart Object layer.
Delete Smart Filters
• To delete an individual Smart Filter, drag it to the Delete icon at the bottom of the Layers panel.
• To delete all Smart Filters applied to a Smart Object layer, select the Smart Object layer and choose Layer > Smart
Filter > Clear Smart Filters.
Mask Smart Filters
When you apply a Smart Filter to a Smart Object, Photoshop displays an empty (white) mask thumbnail on the Smart
Filters line in the Layers panel under the Smart Object. By default, this mask shows the entire filter effect. (If you made
a selection before applying the Smart Filter, Photoshop displays the appropriate mask instead of an empty mask on the
Smart Filters line in the Layers panel.)
Use filter masks to selectively mask Smart Filters. When you mask Smart Filters, the masking applies to all Smart
Filters—you can’t mask individual Smart Filters.
Filter masks work much like layer masks, and you can use many of the same techniques with them. Like layer masks,
filter masks are stored as alpha channels in the Channels panel, and you can load their boundaries as a selection.
Like layer masks, you can paint on a filter mask. Areas of the filter that you paint in black are hidden; areas you paint
in white are visible; and areas you paint in shades of gray appear in various levels of transparency.
Use the controls in the Masks panel to change the filter mask density, add feathering to the edges of the mask, or invert
the mask.
Note: By default, layer masks are linked to regular layers or Smart Object layers. When you move the layer mask or the
layer using the Move tool, they move as a unit.
