Applied filter but want to adjust it later? Smart Objects let you edit filters, transforms, and adjustments anytime.
Convert to Smart Object:
Right-click layer → Convert to Smart Object
Why It Matters:
Regular layer: Apply Gaussian Blur → Permanent, can’t adjust
Smart Object: Apply Gaussian Blur → Double-click filter anytime to change blur amount
Bonus: Transform (resize, rotate) smart objects 100 times with zero quality loss. Regular layers degrade each transform.
