-
- To address the question of why most major technologies were developed in
- the 50's and 60's:
- This observation results from ignoring developments outside that time
- frame.
-
- As the original list indicated, important innovations came along
- in the 30' and 40's. The original list excluded all innovations prior to
- 1930. That ignores some *very* important advances in photography
- such as development of the mechanically timed shutter, which allowed
- for reasonably accurate exposures under 1 second, and the development
- of the roll film camera which gave people the freedom to take a series of
- pictures without fumbling with bulky film holders.
-
- As noted above with the "^^^^^", a number of modern advances have been
- eliminated from the count by simply ignoring that they are advances.
- I believe the 70's and 80's have seen real advances in lens technology
- (better coatings, wide range of high quality zoom lenses, low dispersion
- elements for elimination of most chromatic aberration....)
- The incorporation of modern electronics in cameras is a general category
- of innovation that includes a variety of specific
- innovations such as TTL flash control,
- electronically timed shutter, programmed exposure automation,
- auto focus and matrix metering.
- These are all (relatively) recent innovations which have greatly enhanced
- photographer's capabilities.
-
- Innovation didn't taper off after the 60's, and it hasn't stopped yet,
- either.
