The TO mask, taken with a digital camera as reference
The Nishika N8000 3D is a 4 lens camera from 1989 that could make 3D/Lenticular prints which could be ordered from special print shops using dedicated printers. Well, those places are all gone now, so I used mine to shot doubles with masks. First run was a weekend trip to Toronto, the mask as a T and O with Red Maples leaves (see digital reference pix at end of Album). Second run was in Ann Arbor, the mask was 2 As and Green Oak Leaves.
