Here we are with a b/w portrait using Polaroid 672. I made an educated guess on the exposure time and gave it 5 seconds. Interestingly, I forgot to change the focal length of the camera and made the exposure at 75mm using the zone plate intended for 50mm. I enjoyed using 672 for this portrait as it provided a little boost in contrast. The extra film grain seemed to work out well, accentuating the zone plate effect.
