This is a example of Avoiding Mergers because the background doesnt stand out more the main focus in the frame which is the lady and her child sad about what has happend.
Here is an example of balance beacuse It's perfectly in place the frame is filled with the main focuses the colors are just right the exposure is just right and The camera viewpoint and subject placement were all carefully selected to create this well balanced in the photo
This is a good shot for Rule of Thirds because the shot is vertical but its at a angle to the far right. And the main part is clearly seen in the focus
This is a perfect picture of Simplicity because the main focus is the guy with the flags in his hand. The shot was taking real close so that the background wouldn't be a big destraction of the main focus.
