After many years of working in this light, I found myself on a very wet beach one afternoon in winter and had another epiphany. Midday light worked too, so long as the light was very overcast. I hadn't up until this point, imagined I could get any kind of 'mood' to my work except by working during the golden hours, and since this moment back in 2007, I started to employ working at other times of day, providing that the light is soft.
Over the course of 10 years, I'd gone from shooting only in sunny light, to only shooting during the golden hours, and then finally, coming back to shooting in midday light, so long as the light was soft. My understanding of the kinds of light I could shoot in had altered and I knew that soft light works best.
And then another epiphany happened. Although I would shoot any location if the light was soft, at sunrise, sunset and in the middle of the day, I found that some of the images didn't work because the light had to suit the subject. For instance, the stark black volcanic beaches of Iceland work well if the light is very cold / monochromatic. Composing a monochromatic black beach with warm light seemed at times to be at odds with each other. The landscape didn't really need the warm tones of sunrise, and if anything it was a distraction.
