Developers with timers and alarms to tell you when they’re done have been around for a very long time, as have cameras that focus automatically, and thus know the distance to the target. They even beep when the target is in focus, even if you switch to manual focusing.

A blind person should not have much trouble using any fairly modern film SLR camera, and even several quite old ones, and developing their own pictures.

A blind person should easily be able to use any digital camera as well.

Strange article...not sure what’s supposed to be new.

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...

Like a lot of "inventions", this is a "solution" looking for a (non-existent) problem...!
