One of the things I love to do with photography is to take macro shots - especially of flowers. I also really enjoy taking something recognizable, and seeing what patterns of color I can create by zooming in ridiculously close to the picture when I am creating a design.
The two pics above are a good example. The pattern of abstract pinks and purples was created by turning the thistle pic on it's side, then enlarging the pic as much as I could. I ended up with some nice repetition and colors and pretty much left it as is. I merged a few of the colors to limit the color pallet and voila ! Instant fun.
