When I was in high school, my physics teacher took a two- or three-day digression from the subject book, and went into the subject of photography–chemicals, lighting, etc.
One of the things that he said was that the name “Kodak” came from the sound that the shutter made when it clicked.
Is this true? It’s another one of those “sounds fishy, but could be true,” since I have no idea what the shutters sounded like 100 years ago.
In my experience, most of the “noise” of photography is the mirror swinging out of the way.
