Project 17: Positioning a point

Take 3 photographs in which there is a single point, placed in a different part of the frame, and justify the reason for the position of the point.

The yellow padlock is regarded as a point in this photograph. It is placed at the crossing point of the one-third line from the right and one-third line from the top.


The soap bubble is the point in this picture. It is placed at the crossing point of the one-third line from the right and one-third line from the bottom.


A bird's feather is the point in this picture. It is placed around at the crossing point of the one-third line from the left and one-third line from the bottom.

I think these photographs show that the traditional "rule of thirds" works well when positioning a point.
Coincidentally all of the three photographs above have a vertical line near the point. I think the line adds extra stability to the composition because I can feel the point is attached to the line. If there were nothing in the background, I would feel the point is somewhat adrift and might feel something is missing.
