Iranian Invents Camera for Blind

Back when I had my own darkroom in operation, I specialized in "pushing" (over-developing) hundreds of feet per month of Tri-X to high ASA ratings for available light photography. The operations had to be performed in total darkness -- but it was just a matter of having everything in its proper place, and of memorizing a simple sequence of repetitive motions.

The developer tank didn't have a timer, nor did I have the need for one. The big GraLab" timer(s) on the countertop worked perfectly well -- and they were not constantly exposed to chemicals.

A blind person certainly could have learned to do the film-processing job. Printing the resulting negatives, OTOH...
