I don’t profess to have the answer, but at least for my own photography, I have a hint. I’m using as an example these two photos with the simple topic, fall color. When it comes to telling the story and keeping it simple, quantity comes into play. Quantity comes in many flavors, quantity as in percentage of area and quantity as in sheer numbers. We can use either one of these by themselves or in combination but that danger is the lack of or over use of the subject. And I think the answer I like to use in solving this question is your imagination. I think that the more we can tap into the viewer’s imagination, the less we can have of the subject and still smack them between the eyes with the subject. The more the imagination, the more the storytelling takes over. Both photos were taken D4 / 58f1.4AFS so they are “normal” and they both have the same subject. But they both have different quantity. Which brings the subject to life? It’s for you to answer in your own photos.
