Coming from the folks whose main business was selling film:
On the side of our portable contraption, we shoehorned in a portable digital cassette instrumentation recorder. Add to that 16 nickel cadmium batteries, a highly temperamental new type of CCD imaging area array, an a/d converter implementation stolen from a digital voltmeter application, several dozen digital and analog circuits all wired together on approximately half a dozen circuit boards, and you have our interpretation of what a portable all electronic still camera might look like.
I have used that very photo in my basic digital workshop course material, and I have quoted Steven Sasson for countless of times for opening up a whole new world of digital imagery.
New York based photographer David Friedman had made a nice video profile on Steven Sasson, who fondly revealed that he chose 30 as “the convenient number between 24 and 36” which at the time was the number of shots can be captured on a roll of film.
PS. I have always preferred 24 @ ISO 400.
