Once you've learned the rules for photography, should you learn to break them? Perhaps.
Rules and creativity often feel like antonyms. When you start out in any artistic discipline, it's prudent to learn the foundational rules that make up the basics of the craft. However, once you're experienced and comfortable, should you look to break them? The bulk of my experience is in photography, and to that end, I'd say yes. That's not say you should be trying to break them, but sometimes breaking them just makes sense.
One of my favorite examples of this is our very own Fstoppers writer, Jason Vinson. His wedding imagery seldom plays by the "rules", particularly those pertaining to composition and he does so with stunning effect. His subjects are often places off the rule of thirds in a way that you might expect would lose them in the frame, but instead it creates a powerful overall image.
In this video, YCImaging discusses whether the same approach to rule breaking is necessary in videography too, and giving three examples of ones you ought to break. What rules do you not abide by?
