Rules are meant to be broken. This is especially true of the rules of composition. Photography is not a mathematical step by step formula that has to be followed to get great results. That said you still need to know and understand them in order to effectively bend or break them. Here is one that I broke several rules to make a fun Christmas portrait.
This was made with a fish-eye lens. That was the first rule that I broke. The subject is centered in the frame. That is the second one I broke. See how many more that you can see and ask yourself why I chose to break the rules for this composition.
Photography and art are meant to be fun. Don’t get bogged down in the technical’s of it.
