What can levels do for you???

[almo]

I have been asked i don't know how many times what "levels" does, or how can levels help me?

So I thought I would show everyone that isn't sure what levels is, or if it can really help them in there digital editing a simple comparison. The only change from the original image to the finished imge is a simple levels correction using just the black and white eye droppers. Nothing else other than resizing for the web has been altered. Now I know that some more precise things could be done to really finish a given image off, but I think this is a good example of what levels can really do for an image as far as bringing out true colors and the real light in your images.

If anybody has some examples to add please do so. I would love to see them!
