One of the first compositional rules that I often utilize in my work is the rule of thirds. I recently heard someone say that instead of a rule it is more so a suggestion and this I can highly agree with because using the rule of thirds does not apply to every image. However, I do often advise beginners that one of the ways they can quickly improve their imagery is by thinking about using the rule of thirds when composing which has them placing their main subject at one of the four one-third intersections in their frame.
