You’re Not Using an Object to Focus On
Most of us are used to taking pictures randomly. For instance, if you like a bunch of rocks, you’re going to take a picture of those rocks and call it a day.
While that’s fine for casual photos, if you want to make your pictures stand out, you need an object that the audience can focus on.
That doesn’t need to be anything too crazy. You can use something like a red apple in a bowl with green apples or anything else that stands out from the background and helps your picture look more interesting, and, as the professionals say, helps to tell a story.
