My older niece works at a big chain store as a cashier. Needless to say, her work right now leaves her exhausted at the end of each day of work. So, I made it a point to get her just after work one day and took her picture. And what goes well with an exhausted person? A crying baby of course!
To be clear, the baby was fine, she was just upset her mom, who was right off camera, wasn’t holding her and this session was 3 minutes for her just to minimize the tears.
When bringing themes together in your photo try and think about what you are aiming for. Are you comparing, contrasting, or coordinating (or all three)? It is a lot like setting up your lighting. You don’t just throw light anywhere; you add light that adds to what you are trying to do with your composition. The same is with themes. You must consider what you are doing with them when you use them otherwise you are just rambling randomly at the viewer and unless that is what you are for you need to be organized with what you are adding theme wise.
These photos were done with a single strobe with a grid on that was located just to the side.
