What are Photoshop Smart Filters, and how do I use them?

Smart Filters in Photoshop are a way to nondestructively edit your photo, as well as make changes to a filter after it has been applied to a Smart Objects. Many of the Nicolesy Photoshop Actions implement Smart Objects and Smart Filters, which will allow you to go into the settings and fully customize each filter after it has been applied. Not all images are alike, and you may want to apply these actions to files which vary in their image size/resolution. Smart Filters make it possible for each action to work perfectly for nearly all of your photographs. To edit a Smart Filter, click on the filter name below the Smart Filter mask. The filter will pop up and allow you to make the changes you need.
