Abstract
A method for recording lifelike images of human subjects comprises the steps of illuminating the subject with a light source of substantially the same color as the wavelength of the laser to thereby simulate the laser for at least a predetermined time period necessary to adapt the subject's eyes to the intensity level of the light source; extinguishing the light source; opening the shutter; and activating a pulse laser, wherein the extinguishing, opening, and activating steps are performed within a time period of approximately 0.5 seconds.
