Applying filters to Smart Object Layers

Typically, when you apply a filter to a layer in Photoshop, you make permanent changes to the pixels of the image. For example, if you apply a sharpening filter to an image, you can’t reduce the amount of sharpening after it has been applied. With Smart Objects, you can apply filters and make as many adjustments as you wish. To apply and adjust a filter with Smart Objects:

  1. Click on the Smart Object in the Layers panel to make it the active layer;
  2. Navigate to Filter > Sharpen > Smart Sharpen. Make your adjustments to the settings in the Smart Sharpen dialogue and click OK to apply;
  3. Photoshop will show the filter as a sub-layer with a dedicated layer mask for the filter. You can use this layer mask to exclude the filter from areas of the Smart Object;Smart Object layers filter applied

  1. In the Smart Object layer, double-click on the name of the filter you want to edit. In this example, double-click on the words Smart Sharpen under the Smart Object thumbnail;
  2. In the resulting dialogue box, make your changes to the filter. You will notice that the initial settings have remained intact;
  3. Click OK to apply your changes.Smart Object layers edit filter applied

You can edit a filter on a Smart Object as often as you wish, without degrading the quality of the image.

Transforming Smart Object Layers

Smart Object layers give you the ability to rotate, re-size, skew and warp the contents of the Smart Object without losing any image quality. Typically, when you transform pixel-based contents, the image degrades further with each transformation. Because Smart Objects are protected inside a housing, they are not directly affected by changes and you are free to make as many transformations as needed, without fear of harming the pixels.
