Aging lends pictures a certain “look” resembling that of old photos. The
process first produces a grayscale picture from the original and then
reduces the intensity of the blue and green color values, so that the final
picture appears darker and redder. In the middle example, the aging
degree was set to 0%, on the right it was 15%.
Posterize reduces the number of colors in the picture. The fewer colors,
the more flat the picture appears. In the right hand picture below the
number of colors was reduced to 8. The results of this filter are not always
good.
The Pop-Art filter is supposed to change the colors of the picture to a
pop-art format, but unfortunately it does not seem to function correctly at
present.
Charcoal sketch makes the picture appear as if it had been drawn with
charcoal. The outlines are in black and the original colors are suppressed.
