The only way to figure out what works in photography is through trial and error. Once you get enough experience, it is easy enough to find the right exposure. That’s not the biggest challenge. What really takes experimentation is figuring out what will satisfy your desire.
That is something only you can figure out. It’s not measured by likes or shares. You have to know it when you see it. It has to click when you push the shutter. It is some mysterious combination of subject and composition, some moment that you are able to capture or create.
