Metal Text

	To start, create some text that is glowing (consult the glow tutorial now). The standard red-yellow-white glow works particularly well. Make your text as big as possible - I've had to keep it small here to save space, but you should make it larger.
Apply charcoal: ... and invert:	Next apply the charcoal effect, and then invert the picture. That's it! Instant metallic text. Remember that your attempts will look better than mine, because you can afford to make the text bigger.
	An alternative way to get more mileage out of this effect is to create a gradient mask on the alpha channel similar to the one on the top left. If you then apply the charcoal effect, and don't invert it, you get some interesting results - like the picture in the middle left. In the picture in the bottom left, I also increased the pressure of the charcoal effect from 0 to 100%. See the big difference? There's loads of things you can do with this technique!
