This digital composite is built on 2 photographs I shot while driving to a client in Connecticut from JFK at about 1 AM.
1) The inner concentric rings is the first image that I used.
2) The next step was the mathematics. As it needs to be a circle, I needed and even number of 1/2 blades to align into a perfect circle without overlap. I determined I could fit 16 blades or 32 half blades based on the photo of the light.
3) Using Adobe Photoshop's Puppet Wrap, I forced the image to fit within a pie shape of 11.25 degrees (360 degrees / 32 slices) so that I could get the shape needed to create 1/2 the blade of a turbine.
4) That image was then duplicated and flipped to create the full blade and provide symmetry of the lights within the blade.
5) Next was the replication of each blade and positioning until I had a complete circle
6) At this point, I flattened the circle and duplicated
7) From the duplicated circle, I shrank the circle and placed within the larger outer circle. I also rotated it by 11.25 degrees to get a subtle twisting of the image and to align the edges together.
8) Duplicating and shrinking of the circles continued until I had the depth I wanted for the concentric rings.
9) The outer purple lights came from photographing the Stamford train station as I drove past it. The solid purple ring was where the length of the fence had no slats so the light was solid. The long skinny lines were from the vertical purple neon light tubes as they appeared between the gaps in the slats.
10) Creating the purple ring was the same technique as the inner circle's creation except I did not use puppet warp, rather I used perspective to keep the lines straight but to angle to that they pointed to the center of the circle.
The effort to build this image was about the same as my others, but due to its size (8GB), it would take up to an hour to save each time.
