Lightning

   In the photograph which is shown on page 712 in the textbook, I see a striking image of a lightning. There is definitely a cause and effect relationship shown in the photo. In addition, more than one example of this relationships can be found. The friction between hot air and cold air combine with chemical reaction cause the lightning, which hits the tallest tree on the ground, thus causing the smoke and the tree to burn.
   In this picture, the color is strongly contrasted: the sharp bright light from the lightning compared to the rest of the empty space which is dark blue. When first looking at this photo, my eyes are drawn to the lightning because it’s the only focused and clear image. It’s the one that stands out most, which results in my attention being first paid at it. Only when looking closer at the image, I can see there are other things, such as: trees, houses, and fencing. Other than this technique, there is also the usage of relative sizes of objects in this photograph. In proportion, the huge lightning is contrary to the small houses. Also, the photographer uses the empty space to imply the endless power of the lightning.
