Titanium

Titanium is another 'metal' effect, but it's less colourful and less extreme than the Iridium filter. The controls are a lot simpler, too...

Smoothness	The effect usually looks better when some smoothing is applied - but this function will slow the filter down considerably at high settings.
Frequency	This slider controls the frequency; the higher the setting, the more bands of brightness variation you'll see on the image.
Intensity	This one controls the intensity with which the metallic banding is applied to the image.
Strength	And this one controls the overall strength of the effect.
Subtle/Extreme	For traditional metal effects, use the 'extreme' setting. The 'subtle' setting scales down the other controls, giving effects that are less obviously metallic, but arguably more useful!

	This is the result with the default settings - quite extreme, really, I suppose...
	More extreme still, and things begin to look decidedly abstract...
	But more subtle settings give a result that's less metallic, but exaggerated brightness levels.
