It may be second nature for you to open the Photoshop graphics software and use it to work on your digital photographs, but keep the program in mind for other kinds of artwork as well. Photoshop offers artistic tools for digital doodlers as well, with many options for coloring, drawing and painting right on the screen. With a couple of quick clicks, you may find that your computer monitor serves as a creative canvas.
Open Photoshop, click "File" and select "New." Type "Color" into the "Name" box and set your preferred drawing dimensions. For a full page of drawing, type 11 inches by 8.5 inches. Pull down the "Color Mode" menu and select "RGB Color." Pull down the "Background Contents" menu and select "White." Click the "OK" button to open the workspace.
Double click the top-left square of the "Color Picker," the two overlapping colored boxes on the "Tools" palette. Select a paint color from the rainbow and click the "OK" button.
Click the "Brush" tool, which looks like a paintbrush, on the "Tools" palette. Pull down the brush menu at the top of the screen, the second button from the left. Select a solid, round brush head, such as #55.
Position your cursor on the "Color" box and draw the outline of a design, such as a flower or heart.
Click the "Paint Bucket" tool, which looks like a spilling can of paint, on the "Tools" palette. Click inside the outline you just drew, which fills it with the same color, making it a solid shape.
Switch back to the "Brush" tool, change to a new paint color and select a different, smaller brush head. Move the "Opacity" slider bar down to 30 percent. Color more designs on the drawing. Notice that now, the colors are semi-transparent, since their opacity has been turned down.
Move the "Opacity" slider back to 100 percent. Click the "Paint Bucket" tool again. Select a new color from the "Color Picker" that hasn't been used yet in the drawing. Click the white space of the "Color" box, which fills with color behind the drawing.
Click the "File" menu, select "Save As" and save the file to the computer.
