Copy and Edit Smart Filters in Photoshop
Smart Filters let you apply Photoshop filters non-destructively so you can re-open settings, change blend/opacity, and mask the effect. This quick guide contrasts destructive filters with Smart Filters, then shows you how to convert layers, edit filter settings, and reuse effects efficiently.

Step-by-step instructions
See the limitation of destructive filters
Apply a filter directly: Filter → Liquify; make a visible change and click OK.
Apply another: Filter → Filter Gallery → (e.g., Artistic → Sprayed Strokes).
Notice you can’t re-open or adjust previous filters—this is destructive.
Enable Smart Filters with a Smart Object
Right-click the image layer → Convert to Smart Object (look for the small Smart Object icon).
Now any filter you apply becomes a Smart Filter you can edit anytime.
Apply and re-edit Smart Filters
Run Filter → Liquify; make adjustments and click OK. A “Smart Filters” stack appears under the layer.
Double-click the filter name (e.g., Liquify) beneath the layer to re-open and modify settings at any time.
Adjust Smart Filter blending and opacity
Double-click the Smart Filters blending icon (to the right of the filter name).
Change the filter’s blending mode (e.g., Hard Light) and Opacity to control how it mixes with the layer, then click OK.
Mask Smart Filter effects non-destructively
Use the Smart Filters mask thumbnail below the layer to paint with black (hide) or white (reveal) the filter effect on specific areas.
Refine with soft brushes to blend transitions.
Copy Smart Filters to another layer (reuse)
Ensure the destination layer is also a Smart Object (Right-click → Convert to Smart Object).
Drag the Smart Filter(s) from the source layer’s stack onto the destination Smart Object layer to copy and reuse them.
