PHOTO #1: I kept my camera lens very close to the metal object. I was very close and played with the focus adjustments to get the perfect amount of blur and focus.
I was looking from the side of the metal object.
This photograph was taken in a horizontal manner.
I considered the rule of thirds by adding a focal point and blur in the front and back closest and farthest away from where the photo was taken.
Photo number 1 leads the viewers eye through all of the shapes and colors and shadows. Your eyes will try and figure out the complex shapes. Some people may think it is many different things.
