Hard Light    Paints in Multiply or Screen mode, depending on the applied color’s 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. Pencil tool
