Photography

 This photograph incorporates the use of shallow depth of field.  The pumpkin in the front is in focus but the one right behind it is slightly out of focus, and the background is out of focus even more.

This photograph incorporates the use of balance.  The bowl of fruit on the right is balanced by the chair at the table on the left.  They balance each other out making the photograph more appealing.

This photograph incorporates the use of the rule of thirds.  My cute wife is framed so that she is not right in the middle of the shot, instead she is framed on the intersection of the thirds grid line.  This makes the photograph more interesting than if she was framed right in the center.
