Did you know that when you create a smart object, you can easily switch out the image that it contains? This means you can maintain the smart filters and adjustment layers, and apply the exact appearance to a different image. Right-click on the name of the layer that contains the smart object, and choose Replace Contents. Navigate to a different image, click Place, and it will replace the current image in the smart object. This is great for making templates and other reusable assets.
