Water Glare

	To start, obtain an image of some water. I made this one using Picture Publisher's texture fill tool; the texture is a repeating tile of water that comes with the program.
	For this next and final step, you will need to be familiar with the tone balance control. Glare is simply too much reflected light; we are now going to abuse the tone balance control to over-process the image. Grab the highlights marker, and move it a long way to the left. Keep checking the preview. You should see the water develop a nasty, eye-burning glare. Fantastic! Place in a picture with bright sun, and you're away..
See? Told you, blink and you'll miss it. Easiest effect in the world...

Aside - doing it the wrong way.

Just as an aside... the image on the left is the same water picture, but this time I've used the brightness control instead of the tone balance control. See how instead of glare, it just makes a picture that is brighter? This is why the tone balance tool, with its greater level of control, is the preferred option in most cases.
