In Australia, from the extreme tropical north to the cool temperate south, there is a vast array of weather conditions. Light is directly affected by the weather, which, in turn, is influenced by topography, latitude and longitude, and season.
Over the many years during which I have battled with natural light, I have learned to defuse my aggravation and, rather, broaden my preparedness to work with varying light conditions. I discovered that different subjects are best shot in different lights, and that angle of view, choice of film stock, lens selection, perspective, and so on, all play a role in enhancing "bad" light.
There's no point in shaking your fist at the sky. Turn the negative to positive and you'll get some great shots, even if they weren't what you originally planned.
