My “5 Fs” (finding, figuring, framing, focusing and firing) was conceived to help photographers remember the things to consider when photographing a subject in real life situations. If you practice this system it will become your working technique as a street photographer.
The second “F” is FIGURING.
Hooray! You see a situation or subject that you think will make an exciting photograph. Now what?
Throughout a subject area, there are many elements, factors and details that when effectively combined in the photograph, help give the center of interest more strength. The only difference between the average photographer and Henri Cartier-Bresson is that Bresson considered every detail and he only included those that would enhance the center of interest and he excluded those that would detract from it.
To figure this out you must take an instantaneous visual inventory of what you have to work with and then you must consider which to include and what to eliminate. Ideally you will include at least three things to put together with the center of interest that will strengthen the photograph.
For example, when I saw the two boys in this photograph I realized they would be a great subject because of their movements and their excitement about bathing in the Ganges at dawn. I knew that there were other important details, such as the empty boats in the foreground, the crowded boats and the lighting, that I wanted to include. I wanted to emphasize that it was dawn so I wanted to show the light on the water which would give the photograph a mysterious quality. I also knew that moving in close to the boys was the most important thing of all so I eliminated parts of the boats. I also thought it important to include that the boats in the background that were crowded with the people as a contrast with the two boys in the water. I chose the vertical format so all three elements were visible and I positioned myself so that the boys were the center of interest and were between the two boats in the foreground and the crowded boat in the background was still visible.
