The common definition of drawing is the representation of forms or objects on a surface by means of lines or marks. Typically, this is done with a pen, pencil, or marker. In the computer, drawings can be made by manipulating a mouse or stylus. Combined with Adobe Photoshop’s pencil tool, the hard-edged, freehand lines that define drawing can truly be reproduced.
With the addition of a stylus and graphic tablet, the process of drawing, erasing, and even shading can be replicated. A stylus can be programmed such that one end acts as the point of a pencil and the other as an eraser. The artist can then physically draw in the same manner as they would with a pencil. In many paint programs, the pressure used while drawing with the stylus is also reflected on the screen. Settings such as the opacity of the pencil line and additional tools that smudge and blur allow the stylus to switch from pencil to fingertip and back again to get the desired look and feel. Especially when working with artistically talented clients, it is important that the therapist know how to share appropriate computer tools that will allow them to generate the kinds of images that match their pre-existing artistic styles.
