Photoshop is a powerful image editor that can be used to create beautiful graphics and photos. However, it can also be used to create filters, which are pieces of software that allow you to change the appearance of your images. One of the most common filters is the filter mask. The filter mask is a box that appears in the bottom left corner of an image when you select it from the Filters palette. The filter mask allows you to change the appearance of all of the images in an image, regardless of whether they are saved as JPEGs or PNGs. To use the filter mask, first select it from the Filters palette and then click on its thumbnail to display its properties. The properties for a filter mask include its name, type (filter), and size (in pixels). You can also click on its thumbnail to open its dialog box, which contains information about how the filter works and how you can use it. The most important property for a filter mask is its size. This tells you how many pixels wide or tall the filter will be when applied. If you want a large filter mask, then you will need to make sure that your image has enough space in order for it to display properly onscreen.
