In order to view the animal markings differently, I tried a lot of different photo apps that are available through iTunes. These allowed me to make a negative, a sketch like image, and an artistic rendering. There is now even an app that lets me trace or draw over the image and then save the file with or without the image in the background. I also freehand (with either a Rapidograph or Nexus pen) traced or drew the image and then also began to simplify some of the patterns appearing. Below is the legend to help explain what technique was used where.
