The rule of thirds is a very basic rule that is so simple but goes so far when it comes to its application in nature photography.
Rule Of Thirds ; dividing an image in three equal parts vertically and three equal parts horizontally. The intersections made by these lines are the focal points of an image.
If you look at these images you will see that I have divided them as per the rule of thirds. When I set up these shots I purposely placed the subjects that I wanted to highlight into the intersections. By doing this I made these subjects the first thing you look at when you see the photo. Your eyes will go to these focal points first automatically without you even knowing it is happening.
Why? It is a natural thing that you do. Survival as a human depends on it! You have been doing it your entire life. Every day you use this skill without thinking twice about it. You first learned it as a baby. When you where a baby and could not communicate with your mom and dad you looked at there faces to get your information. More importantly you looked at there eyes and mouth. If they were smiling you knew everything was ok and you where safe, there eyes bright and wide and the corners of there mouth upturned. If they where scared you also knew to stay close to mom and dad. If you have kids you know how this works. It is the reason a baby smiles when you smile it makes them feel safe.
