The Name of The Technique

Simplicity- the blue background is simple so your eyes forced to focus on the two building on fire.

The Rule of Thirds-

In this photo the helicopter is
in the top left corner so it looks
like the helicopter is gonna fly across the picture instead of off
the photo.

Lines-
the people in the line, as you follow them you being to see the destruction.

Balance-

the photo shows the city kind of a
calm time so the city is in balance.

Framing-
in this photo the mother and daughter are morning together
in the center of the photo.

Avoiding Mergers-

in this photo the solider is holding his gun
with his fellow soliders behind him so there is nothing werid like coming out of his head.
