Here are some more examples of rule of thirds in photography. I used a overlay grid to these first two photos to show how the rule of thirds was used.
The photo below is an illustration of a situation where photographers often make one of the most common photography mistakes, a composition that involves the horizon.
It's almost always a bad idea to have the horizon divide your photo into two equal halves. Instead I used the horizon and divided by a third as well as place the sailboat 1/3 of the way to the right.
I placed the horizon on the bottom third of the photo to put the emphasis on the sky, which was more interesting than the water in this case.
Here's an example below of how you can create balance in the composition of your image even if it's an abstract photo. The bottom third is slightly thicker than each of the top 2 thirds, but that's okay because it acts like a base for the rest of the photo to sit on.
The photo below is rather symmetrical and not a great composition. Don't get me wrong. It's not a terrible composition, it's just a little too static. It has some interesting early Fall colors and pleasant reflections in the calm water.
One of the purposes of this web site is to get you to look for ways to improve your photography as you shoot them. If the main purpose of the photo is to get a real good look at the Gazebo, then this is a better photo than the one farther below where I used the rule of thirds.
I backed off a bit with the zoom and aimed the camera a bit more to the right. This made the stream a leading diagonal line coming in from the right and leading our eye to the Gazebo.
This example was shot in early Fall in the northeast part of the U.S.A. and the tree colors were not yet fully pronounced. It was a dull, overcast day with flat lighting so these are not great photos by any means.
You may not be able to control everything in your photography, but can often do several things that will produce a better photograph and using good compositional technique is one of them.
I was just walking around my neighborhood early one chilly morning with my Canon 5d Mark iii attached to my Rocketfish RF-TRP47C carbon fiber tripod and saw this frosty leaf and grass.
I am a nature geek and often am fascinated by the simple things. I thought it was very interesting how the frosty water crystals formed around the edge of this oak leaf.
Naturally without thinking, I composed the photo by placing the leaf at the approximate intersection of those two vertical and two horizontal lines that divide the camera frame in thirds.
Here's another rule of thirds example. You can get some really interesting compositions by zooming in your subject. Emphasize the brilliant colors of the peacock by filling your frame and including no background.
Although his neck is almost perfectly centered, the tilt of his head make it work. Technically, this is not an exact use of the rule of thirds. You, as the creative artist, have the power to adjust the exact placement of your main subject where it "feels right."
If I had place the peacock's head exactly at the rule of thirds intersection, the photo would not have had good balance. It's a very objective rule that should be used subjectively. Have a blast.
I did a search on Google and here was one of the top responses on the rule of thirds definition:
Here's a final sample photo of the rule of thirds in a composition. I was most intrigued by the reflection of the flag in the window on the front door. I had to wait patiently until the window had it blowing in just the right manner.
The main subjects, the flag and the red door, were placed at the intersection of the horizontal and vertical guidelines.
Keep shooting. Keep learning. Keep improving.
