One more war story from an old warrior, if you count fighting against the inevitable encroachment of things digital. Once upon a time I was employed by NASA to do research in human factors. One of our aims was the mathematical representation of "The" human operator. The hope was to minimize development time of new control systems while keeping the man in the loop, as well as to minimize danger to test pilots. If you can get past the paradoxical idea of finding a math model of the man that can take his place for the purpose of designing a control system that will allow him to keep his place, you can see the need for a general purpose computer that is fast enough and accurate enough to do the job. In 1960 there was no such digital computer. We used analog computers with vacuum tube amplifiers, linear to plus or minus 100 volts with so little phase shift that you could connest the output directly to the negative input without oscillation. Feedback through a large capacitor made an amplifier into an integrator over time.
By the time I retired in 1982, we could retire our analog computer. One huge supercomputer was doing all the data reduction, bookkeeping and driving of dynamic simulators for the whole Langley Research Center.
If our only arguments in favor of the traditional methods of photography are no better than they have been, we will lose it except for those who really return to its origins. My grandfather had a 5x7 plate camera that was about as portable as one could get then, and left over 100 of those negatives to rot in the attic after he died. I was able to rescue many of them by D*****l (expletive deleted) means. I'm amazed at what he did with that camera, but I hope I don't have to do it myself that way.
