Shades of Gray
Tuesday, August 29, 2017
Around 1966 my friend John Sullivan who was conscript in
the Argentine Army when I was the same in the navy, argued with me saying that
the world was not an absolute represented by black and white. He was a year
older than I and much more mature. He understood the value of the middle ground
and the shades of gray.
I remember him now more than ever in this world that has
become so polarized in extremes.
A much less relevant topic for most but important for me is
the gulf that exists in photography between the idea of the digital and that of
the analog.
I am no longer the idiot purist of my youth who eschewed putting any kind of filters in my Pentacon F or my Asahi Pentax S-3. I was much too ignorant to know that a yellow filter made b+w film, which was sensitive to UV and blue (more so that with us humans), the film more like the rendering of the human eye. My purist idea was simply a black and white that should have been a gray.
John Sullivan was right.
I am old enough to remember seeing kits for making analog
computers. Here is a definition by Wikipedia:
An analog computer or
analogue computer is a form of computer that uses the continuously changeable
aspects of physical phenomena such as electrical, mechanical, or hydraulic
quantities to model the problem being solved. In contrast, digital computers represent
varying quantities symbolically, as their numerical values change. As an analog
computer does not use discrete values, but rather continuous values, processes
cannot be reliably repeated with exact equivalence, as they can with Turing
machines. Unlike digital signal processing, analog computers do not suffer from
the quantization noise, but are limited by analog noise.
Analog computers were
widely used in scientific and industrial applications where digital computers
of the time lacked sufficient performance. Analog computers can have a very
wide range of complexity. Slide rules and nomographs are the simplest, while naval
gunfire control computers and large hybrid digital/analog computers were among
the most complicated. Systems for process control and protective relays used
analog computation to perform control and protective functions.
The advent of digital computing made simple analog computers obsolete as early as the 1950s and 1960s, although analog computers remained in use in some specific applications, like the flight computer in aircraft, and for teaching control systems in universities. More complex applications, such as synthetic aperture radar, remained the domain of analog computing well into the 1980s, since digital computers were insufficient for the task.
I was a whiz with my simple analog computer that was the
circular slide rule I learned to use at St. Edward’s High School. I did not know
then that it was such a beast, although a simple one.
All the above brings me to the topic of hand, the middle
ground between old technology and new technology.
It may have been Aristotle who observed under a tree
sunlight filtering through close knit leaves and noticing a fascinating
projection of the world beyond the leaves on the ground. It took Leonardo da
Vinci to figure it all out and who is credited with making the first camera
obscura. So, in English that would translate to dark chamber or dark room. Here we had a
dark room without chemicals or enlargers or film. He was ahead of his times. It
wasn’t until 1826 when Nicéphore Niépce’s heliographic image View from the
Window at Le Gras finally combine da Vinci’s dream with his reality saved for
posterity on a sensitized emulsion floating on tar sand.
In photography one (and I) must never forget what came
before. The lastest technology of miniature speakers on the side of a home
computer cannot match the technology of the past in big studio monitors. But if
you have never listened to music with studio monitors then you do have the
ability to judge the quality of music emerging from a cell phone with ear buds.
It took my Rosemary about three and half years to convince
me that needed to get modern or get fu….(the motto of the Vancouver band, The
Modernettes) . And so I purchased a Fuji X-E1and I have been happy since but
without completely abandoning film and metal clunker cameras.
I did (for a short while) adopt the wonders of digital
technology when I purchased an iPhone 3G. I even managed to get the Georgia
Straight to use the photographs I took with it without any comment on their
quality of lack of it. But I soon abandoned the 36 as the Fuji X-E1 was the
better camera and the excitement that some photograph was excellent even though
I had used the 3G wore off. In fact I have not taken one photograph with my
Galaxy phone. Perhaps because the Galaxy has a better camera.
Recently I have gone to my iPhone 3G
files and noticed some nudes I took as an instructor at the now gone Focal
Point. My students mated their digital cameras to a soft-box flash. Not wanting
to intrude I would every once in a while pull out the 3G and take some snaps.
What you see here at the images that can pass muster with the on-line censors.
Notice the neat grain (noise) and off colours. The photographs almost make me
want to pull out my 3G from retirement.
Ample proof that the latest is not always the best. The catch is to remember that past.
