This image was created using three images of the same girl. I shot a series of her with slightly different expressions and positions. I used one image for the face on the left, 2 for the face on the right. Layers were combined using feathered selections and multiple layer masks. Distracting rose elements were removed from the background. The composition was turned into a monochromatic image using channels with selective amounts of color revealed in the eyes, lips and roses.
