All About Aperture

Well since the northeast has been hit by an arctic clipper going out to take pictures is out. And since I moved my house is still in disarray taking pictures is out also. So I have been crusing the web reading little articles here and there on photography.
I stopped my Youtube and found some pretty interesting videos on photography.
This one is about the basics of the aperture and how it works.
I found it informative so I thought I would post it for everyone to check out.
