Last weekend, my wife delivered a beautiful baby boy. Like any proud parents, we took dozens of photographs. A few hours later, I sent out an e-mail (with a photo attached, of course) of the baby to friends and family - a much more efficient tool than having to call people around the world. For many relatives, you also need to make paper-based photographs so I went to the grocery store and placed an order on a Kodak machine for 24 cents each. It struck me after finishing how cheap and easy digital photography has become in such a short period of time. It wasn't that long ago that you'd have to pay 50 cents or 75 cents for a digital print, which defeated the purpose of using a digital camera. Today, digital prints are so inexpensive you can print to your heart's content. At the same time, digital cameras are getting easier to use and the picture quality is has improved in a major way better. For investors looking to jump on the digital bandwagon, Shutterfly just completed an IP0, although it has slumped slightly from its issue price.
