Step-By-Step Instructions:
1. Open a photograph of a person face into Photoshop.
2. Click the "Edit in Quick Mask Mode" button.
3. Select the Paint Brush tool and choose black as your color.
4. Zoom in on the eyes and paint the entire iris of the eye, but not the white parts of the eyes.
5. Click the "Edit in Standard Mode" button.
6. Goto Image > Adjustments > Desaturate.
7. Goto Image > Adjustments > Brightness/Contrast.
8. Adjust the Brightness slider all the way to the left. Adjust the Contrast slider just a bit to the right. Make sure that you don't move the sliders so much that any highlights in the eye get taken out.
9. The eyes in the photograph should now be solid black.
