There are many ways to improve a shot, but most of the time, I feel that simple pictures with single main subject or single idea makes it a good one.
Keeping It Simple Stupid is actually difficult especially when you see more than one interesting subject and you want to combine them.
Sometimes I make a mistake of filming two subjects by placing them in a way that have equal presence in the picture. However, the result is usually not great. Why? Well, the image becomes confusing to look at. Am I supposed to look at A or B? What is the picture meant to tell? The picture feels weak as it does not have a focus.
Sometimes it`s a matter of choosing what the most important subject is when you have two attractive elements. Then you fill the frame with what you want to show most. Emphasizing the subjects to make them look dramatic. E.g. you can get closer to the subject you are mostly interested.
Including everything in the frame will make the picture look weak. Usually there are so many elements in the photos that you can get rid of. They only work as a distraction. When you eliminate the unnecessary, you remain with the best elements.
I recently looked at my footage of the last three years. Let me tell you, there were so much junk that I wondered how I did not get fired until now. One of the great lessons that I have learned as a cameraman is to think before filming. Because if I just turn on the camera and start filming without a thought, I get collection of junk image. On the other hand, if I start filming with a clear message, what I want to show most, clear focus, there tends to be better results.
Keeping It Simple Stupid (KISS), then pictures have more impact and better story telling.
