If you take any spot, different people are going to take pictures from different perspectives. Some may take close-ups, and others will use different angles. There are so many different ways of taking a picture from the same spot.
If you are just reproducing someone else picture then nothing new has been created. Taking the time to take a picture based on what you find important, beautiful, interesting, and noteworthy, results in something new, in something created.
It is the same with content. We need to strive to make something new. To contribute to the collective knowledge.
