These partial faces are from money: French Francs dating back to 1998 and 1997. Up close, these appear as very serious expressions through their eyes.
The art of lines, combined with the color variations were captured to provide this montage by magnifying the images 10×. The lines offer texture and depth to create these facial images.
The original photos for this montage were taken with a Canon PowerShot G9 and a 10x add-on macro lens. Light from an overhead incandescent bulb added a slight yellow tint.
Aperture was used to enhance the colors and highlights, and Photoshop was used to create the montage.
