Smart filters allow non-destructive editing of images in Photoshop. Smart filters can be applied to smart objects and provide the ability to adjust, reorder, or delete filters after application. To apply a smart filter, select a smart object layer or convert a regular layer to a smart object, then choose a filter from the filter menu except extract, liquify, pattern maker, or vanishing point. Applied smart filters appear below the smart object layer in the layers panel and can be reordered or adjusted non-destructively.
