On the left is my original uncropped photo. Once again I played with layers. I had my original as the bottom layer and placed a duplicate image on top. I desaturated the top image (turned it black and white) and then colorized it green. Using the eraser tool I erased the thistle flower from the top layer exposing the purple flowers from the layer below. Then I added another image of a vintage photo lens that I tinted sepia and multiplied the layers.
