Five pictures that I liked.

 Good example of lighting.

 Nice sample of dynamic symmetry.

 Principle of thirds.

 Asymmetrical balance.

High view point and high camera angle.

I take this picture as my favorite among above. This photo comprehends dynamic symmetry, high viewpoint and high camera angle, and asymmetrical balance. On the first, the senior woman who being rescued had accentuated by dynamic symmetry. It shows us the main subject of the picture vividly. High viewpoint and high camera angle is excessively contributing to this scene that a rescue soldier work to rescue a flood victim actively and spectacularly. The last remarkable composition of this piece is asymmetrical balance. A slant line from under left corner to upper right corner is dividing this photo into two contrasting scenes. Flood site and rescue helicopter seem to hell and heaven to me. The eye catching point of this photo is not just variable composition methods, but the photographer's concentration to the main subject and the ambiance such as a moment of block buster movie.
