Fade: The Fade command appears in the Edit menu after a filter has been applied and allows you to change the blending options for that filter. The Fade command also appears after using a painting tool, using an eraser, or making a color adjustment. The Fade dialog box has two options: changing the opacity and changing the blending mode.
Feather: Feathering is the process of blurring edges around a selection. Blurring the edges helps the selection blend into another object, file, or selection when it is moved, cut, copied, and/or pasted.
File: From the File menu, you can choose to open a file, save a file, and browse for a file, and you can print, print one copy, or print with a preview. You can import or export files too or save a file for the web. Files contain the image and all data.
File browser: Allows you to search your physical drives (hard drive, CD-ROM drive, DVD drives, digital camera drives, floppy drives, and zip drives) for files that you’ve either previously created or need to open.
Film: Films enable printers to produce high-quality film positives using a printer. Inkjet films require inkjet printers, and other types of films can be used for laser printers. Films create extremely dense positives, where the black is really black, thus it creates a wonderfully perfect screen.
Filters: Filters allow you to change the look of an image or layer simply by choosing the desired look from the menu options and configuring any dialog boxes that appear.
Flattening: Like merging, flattening an image combines all of the layers into a single layer.
Flow: Used to specify how quickly paint is applied when using a Brush tool like the Airbrush. A heavier flow lays on more paint more quickly; a lower flow lays on less.
Font: Used to create text. Fonts are categorized by family, style, size, and other attributes.
Foreground color: The foreground color can be configured from the toolbox. The foreground color is used when paint tools are chosen and when Fill and Stroke tools are selected. When using a brush or the Paint Bucket tool, the foreground color will be applied. The foreground color is also used by some of the special effect filters.
Frequency: Use this option with the Lasso tools to determine at what frequency or how often anchor points are added as you trace around the object. Values from 0 to 100 can be used, and higher values add more anchor (fastening) points. Frequency is available when using the Pen tool too, with values ranging from 5 to 40.
