Extensions may allow you to change the appearance of an object in your software or add a 3D effect to a video file. Filters are used to change parts of a document. Even if you haven't used Photoshop, you're probably already familiar with some of the popular Photoshop filters, such as the filters used for artistic effects, like the Watercolor and Emboss filters.
