A picture is worth a thousand words, they say. If that's the case, then an interactive picture that you can play with has to be worth more than that, right? 10 thousand words, let's arbitrarily say.

And this is where you can find them!

So far, there are only two in various states of completion:

Depth of Field: This allows you to see how the focal length (lens in mm), aperture (f-number), and distance to subject all work together to determine what is in focus and what isn't. Think blurry backgrounds!
Shutter/F-stop/ISO: These three things work together to produce an image that is correctly exposed. But by knowing which does what, you can control how grainy a photo is, how much motion blur there is, and how much background blur there is. This demo allows you to change the f-stop, shutter speed, and ISO, as well as what mode the camera is in, aperture-priority (Av), time-priority (Tv), or manual mode. Hint: manual mode is the most fun.

Have fun!
