+.Nm qcamcontrol
+.Op Fl b Ar brightness

+.Sh DESCRIPTION
+.Nm qcamcontrol
+is a program to demonstrate control over the Connectix QuickCam(TM)
+parallel port camera and to take a single frame picture.
+.Pp
+If the device not specified, "/dev/qcam0" is assumed.
+If no command is given, then
+.Nm qcamcontrol
+will use its defaults to grab a single frame from the camera. The control
+program will output a portable pixmap (ppm) file to stdout.
+.Pp
+The following options are available:
+.Bl -tag -width "flag whitebalance"
+.It Fl b Ar brightness
+control the brightness of the picture (0..255)
+.It Fl c Ar contrast
+control the contrast of the picture (0..255)
+.It Fl d Ar depth
+16 or 64 shades of gray (specified as 4 or 6 bits per pixel)
+.It Fl p Ar device
+quickcam device (port) (default is /dev/qcam0)
+.It Fl w Ar whitebalance
+amount of white in the picture (0..255)
+.It Fl x Ar xsize
+width of image (320 or less)
+.It Fl y Ar ysize
+height of image (240 or less)
+.It Fl z Ar zoom
+zoom in (1, 1.5x, or 2x)
+.El
+.Sh BUGS
+.Nm qcamcontrol
+does not enforce a proper aspect ratio for x y sizes.
+In practice, standard picture sizes are 320x240 and 180x160 and all smaller
+sizes that maintain a similar aspect ratio.
+Also, the camera is notoriously finicky until you get just the right
+combination of white-balance, contrast, and brightness. Improper values
+will return all-black or all-white pictures.
