Wandering into the world of photography without a backup plan is a lot like wandering into...well just about anything blindfolded. You might think you know the terrain, how to navigate it, and where you're going, but the next thing you know, you've wandered into a forest, caught yourself on some thorn bushes, and lost your pants. And much like losing your pants in this evil forest, losing your photos can be a frightening ordeal!
Think of this scenario:
You spend 10 hours shooting the perfect wedding. The colors are all perfect, the lighting is spot-on, the bride and groom photograph like the two greatest love birds in the world! You get home to your computer, pull all of the photos off of your memory cards, and then go to bed. A wedding is a long day, after all, and you want to get your rest so that you can wake up the next morning and start working your magic!
The next day comes along and you start to edit the photos. Two days pass, you're halfway through the photos, and all of a sudden, a freak storm rolls through town and zaps your house, frying your external hard drives, and wiping out 10 hours worth of photos. You have nothing to deliver to your clients except the crisp shell of metal and magnets, or whatever else goes into a hard drive. You have that, and jar after jar of tears, because you've spent the last 24 hours crying away the pain.
