Framing

this is framing because the two fire men in the front make contrast to the city in the background making it look huge

Mergers

this is a merger because of the piece of the fallen building in the front matches the building in the back

Balance

this picture is balance because you can see both towers making it somewhat symmetrical and there is more than one object in the picture there is a smooth blue background also

Rule of Thirds

this is rule of thirds because the people in this picture are in the bottom left which allows you to see the letters displayed on the board

Horizontal and Vertical Lines

the lines on the metal piece from the plane bring your eyes to the windows, also the screws that look like dots form lines along with the other pieces of metal

Simplicity

this is simplicity, the building is the only thing in the picture besides the blue sky background
