Hard Light Paints in Multiply or Screen mode, depending on the
applied colors lightness value. This mode is similar to Soft Light.
However, painting with black produces black; painting with white
produces white.
Darken Compares the underlying color and the applied color, and
the result is whichever color is darker. In other words, pixels in the
image will be painted if the paint color is darker, while pixels that are
darker than the paint color will remain unpainted.
Lighten The Lighten mode is the opposite of Darken mode. Lighten
compares the underlying color and the applied color, and the result is
whichever color is lighter. In other words, pixels in the image will be
painted if the paint color is lighter; pixels that are lighter than the
paint color will remain unpainted.
Difference Compares the brightness of the original and applied
colors, subtracts the brightness value of the darker pixel from the
lighter one, and applies that value to the original image.
Hue Applies the hue of the paint color without changing the bright-
ness and saturation of the underlying image.
Saturation Changes the saturation of the area painted to match the
saturation of the applied color, without changing the hue or lumi-
nance values. Applying gray does not affect the original image.
Color Changes the hue and saturation of the painted area to the hue
and saturation of the applied color, without affecting the shadow,
highlights, or midtones of the original image.
Luminosity Changes the lightness of the underlying color to the
lightness of the applied color, without affecting the hue or saturation
of the image.
Painting individual pixels with the Pencil
You can use the Pencil tool to apply the foreground color to a single
pixel or create a one-pixel, freehand line. If the pixel already uses the
foreground color, the Pencil applies the background color instead.
You can use the Pencil tool for precise image editing at high magnifi-
cations.
To paint a straight line: Shift -drag the Pencil to confine the
line to 90 degree angles.
