Hi. You are talking about me. I'm involved in multiple infringement settlements and lawsuits every year. Perhaps I should point out that I have spent thousands of my own dollars, and hundreds of hours photographing subjects that are rarely seen much less captured with a camera. My images are licensed hundreds of times every month. They are also frequently stolen. If you steal one of my images you are going to get a demand letter. The price will be far higher than any licensing fee. This is because my images are registered with the copyright office at the Library of Congress which entitles me to seek punitive damages.
The writing has been on the wall for decades. Images are losing value because millions upon millions are created every hour of every day. However, some of those images are remarkable and unique. People can make a lot of money if you happen to be the copyright holder of these images.
An example I like to give is the photographs Gary Rosenquist captured of Mt. St. Helens exploding and the side of the mountain sliding away. Nobody else captured this sequence. Not even close. These images make substantial licensing fees to this day.
I've long been fascinated by the fact that a camera can capture subjects the human eye cannot properly perceive. It just so happens that this obsession has led me to create images that are hard to imitate. I feel no guilt in charging fees for my images. I feel no guilt about pursuing people who have stolen my images for their own projects.
If you are photographing bald eagles with an American flag in the background or frosty fall leaves artfully arranged on the ground - I agree with the gist of this thread - these images are worth practically nothing. But this not universally true for all images.
