Creating tool presets in Photoshop is an excellent way to speed up your workflow and remember your favorite and most-used settings. A tool preset is a named, saved version of a tool and specific related settings such as width, opacity and brush size.
To work with tool presets, first open the tool presets palette by going to “Window > Tool Presets.” Depending on the current tool you have selected in the Photoshop toolbar, the presets palette will either display a list of presets or a message that no presets exist for the current tool. Some Photoshop tools come with built in presets, and others do not.
