That's a non sequitur on every level. For one, of course professionals use digital cameras these days; surely you didn't think they only used film? There are digital cameras that are far more high-end than any camera phone, just as there are film cameras far more high-end than a Kodak disposable. Second, cropping isn't the only thing that defines good photography. There's lighting, composition, shot selection, the ability to bring out the essence of one's subject -- matters of artistry, skill, and experience rather than mere equipment. It's a skill like any other, something that a trained professional can do at a far higher level than an amateur. Now, I've been told I have a pretty good eye for composition when I take snapshots, but I would never be so arrogant as to think I'm anywhere near qualified to take professional-level photographs that would be worthy of publication in a magazine. There are people who devote years of training to become good enough to do photography as a profession, and it's not only naive but insensitive to dismiss what they do as just a matter of pointing and shooting, something that any random person could do at an equivalent level.
