The light that outdoor/landscape photographers write with is overwhelmingly provided by mother nature.
At times, augmented by mankind.
Sunrises, sunsets, rainbows, halos, fog, mist, rain, virga, cumulonimbus, cumulus, cirrus, stratus clouds, lightning, hail, wind, dew, snow, ice, hoarfrost, drought, floods, tornados, hurricanes, dust storms.
These are brought to us and controlled by weather. You might, by extension, also include the timing and quality of spring flowers, fall leaves, and bird migrations. Perhaps even stretch to include geological features controlled by water, wind and temperature or lack thereof.
Read Galen Rowell's "Mountain Light" and understand that you can know and 'reasonably' predict the type and quality of light.
Fog = cold air over warm water or warm/moist surfaces. (think of a steaming cup of coffee or hot tea)
Light winds so the fog doesn't blow away.
I had my share of physics classes in both high school and college. I used to
have some idea as to what a photon was, the dual nature of light - wave and particle, how to calculate the impact of convex and concave mirrors and lenses, etc. None very helpful to photography other than the process of learning how to acquire and interpret information and how to solve problems. I'm sure it would be helpful if I worked for Canon or Nikon and were designing lenses. As a photographer, however, I'm not. I'm not discounting physics at all, and I am fascinated by it. I'm just not sure it's applicability to photography any more
than biology, anatomy, architecture, interior design, geology, engineering, or economics for that matter.
Look at the paintings of Frederick Edwin Church and Albert Bierstadt. They had command of light. I doubt they were physicists.
Look at the old B/W photographs of the dust bowl by Dorthea Lange.
Go see Kevin Carter's 1994 Pulitzer Prize winning photograph of the starving child stalked by the vulture.
Weather plays a pivotal role in a great deal of both the beauty and tragedy we experience throughout life.
Who knows, a career in meteorology could actually put you in places where you could see and experience and interpret and record and share through photography the beauty of the sun rising through mist, the wrath of a flash flood, crocus pushing their way through snow, or hunger brought on by drought.
I came; I saw; I shot; I shared.
