Hello all,

I was browsing the other day and came across two very informative / educational videos about photography.  The first video is from the Science Channel's DeConstructed show.  They take an in-depth look at how modern DSLRs work.  I like that they take apart the camera and show how each piece works and explain it's purpose.  That link is right here:

The second video is from the Discovery Channel How It's Made show.  This clip explains how modern photographic lenses are made.  Surprisingly, its still largely a hand-made process, which explains why some lenses can cost several thousand dollars!  Enjoy!
