Exposure is composed of three variables that have tremendous impacts on each picture. One of the greater challenges to the photographer is to bring to life still image. To help our brain appreciate what is happening using various exposures settings.
Our eyes, when looking at a subject, can isolate the subject from its surrounding. We still see around the subject but our attention is locked on what we are looking at.
Another aspect is that our eyes are seeing action as its happening. You’ve looked to a car on the highway and you saw the spinning wheel being blurred while the rest of the car is clear and sharp. This is one of the capabilities of our eyes combined with our brain.
When we are looking at a picture, everything is static and nothing really moves. So if we are looking at a picture of a Helicopter in the sky taken at 1/4000s, the blades of the helicopter will not move and our brain would think that this helicopter is falling. Should the blades had move they should have been blurred.
In this picture, the person is waving its hand. This is clear. Should I have taken this picture at 1/250s instead of 1/50s, the hand would be totally stopped and our brain would not understand why this girl had its hand up there.
When we understand how our brain work and what need to be fed to our brain in order for it to appreciate what’s happening in the picture, we are making leaps and bounds forward in our photography.
Additionally taking this picture at 105mm on an APS-C sensor at f/4.5 helped tremendously blur the background which did mimic the way our brain is isolating subject when we look at somebody waving his hand.

Do you ever use Exposure speed creatively to help the brain of your audience appreciate what is happening?
