Exposure control explained and shown.

This is an amazing link which thoroughly covers all types of exposure settings and you can actually play with the settings and see the results. This is great for anybody just getting into photography and still needs to learn the basics.

I would add to this a display of the resulting histogram.
I wonder how hard it is to do that?
If you shoot raw then reprocess over and under exposing.
Then the only problem is putting it into HTML or flash.

That's interesting....always wondered why someone hadn't done it.
