Who doesn't love digital photography? The technology has become inexpensive enough that it's available to the masses. It's become low-tech enough that anyone can learn to use it. There's no film, so there's no worry that it's going to cost you a fortune to develop your images (until, of course, you actually decide to develop your images).
 
That question isn't hypothetical, though: Who doesn't love digital photography? Editors and writers like me who have to deal with people who don't understand digital photography.

I'm sometimes asked to gather photos for the stories I write. Sometimes it's a matter of just going to my barn and taking pictures with my Canon 20D. That's easy enough, it's fun, and I'll know I'll get the shots I want. I don't love digital photography, though, when I have to work with sources and product reps who don't understand the resolution requirements of the publications I work with. Here's a quick tutorial, in case you're not familiar:

Photos are actually made up of teeny-tiny colored dots. When you publish a website, you can use very low resolution photos, and they look just fine because of the configuration of computer screen resolution. When we print photos in a publication—magazine, newspaper, brochure—the photos need to have so many dots per inch (dpi) in order to print crisp and correct. The minimum resolution for most of the publications I work with is 300 dpi. Lower than that, and Foxy's face will be fuzzy.

People who don't know the difference tend to set their digital cameras on the lowest setting. They figure that the images will be easier to work with (smaller files e-mail easier and upload to websites faster), and they realize they can get more images on a photo card because lower quality photos consume less memory. What they end up with is a lot of tiny, fuzzy images for personal use. What I end up with is nothing that's suitable to print.

High resolution, folks, is the way to go! Just spend the extra money on the larger memory card. Better yet, buy two in case one of them fails. And please, please don't argue with me when I ask for a better-quality image. I'm usually not knocking your photography skills; I'm just looking for something that's suitable to print. I'm not making up this 300 dpi rule, I swear.

There'll be more on this, as patience allows. I can only take so much low-res talk in one day before I start cursing.
