Simplicity

What I really wanted from this filter was a sort of 'Japanese-woodcut' look. Well, I tried hard and I'm sure you'll agree that the end result looks absolutely nothing like a Japanese-woodcut. Never mind, you can't win 'em all. I still rather like the effect, even if it didn't quite work out the way I intended.

The controls on this one are reasonably straightforward:
Simplicity The filter reduces the image to areas of similar colour - rather like posterisation, but a little more subtle. This slider controls the number of colours - the degree of 'simplicity' to which the image is reduced.  
 
 
Outlining style The areas of colour can be outlined in four different ways: None, Fine lines, Embossed (gives a raised effect), or Intaglio (gives a sunken effect). Select the style you want from the drop-down.
 
Immediately below the drop-down list, a set of three radio-buttons allows you to choose from Natural, Dark, or Light outlining, which each give a very different 'feel' to the result.
Outline strength With this slider, you can control the intensity of the outlining effect.
Colouration This works in exactly the same way as the colouration slider on the Abstractor plugin. At the default setting, the colours remain more or less the same as in the original image; the low settings take the image down to monochrome, while high settings give an exaggerated colouration.

 

This was taken at Cregennan, in Wales; it's a beautiful place, to which this image in no way does justice. The light was dull, the weather strange... oh, and I'm a lousy photographer too, which doesn't help.
The default settings give this kind of result. I used the 'Fine lines' style.
On this one, I used 'Emboss', and boosted the colouration a little.
Finally, this is the result after setting the colouration down to only a little above minimum.
