“You're a pro. I understand why you copyright your photos, but why should I worry about it? I'm not selling my photographs or using them in my work.”
It's important to understand that every time a photographer, or even a weekend vacationer presses the shutter release on their camera to make a photograph, the image is copyrighted the moment it's made. That's right, every photo made is copyrighted, the instant it's stored on film or in a memory card.
But that's just the start.
