FRISCO — There’s almost nothing better, from a photography standpoint, then when an approaching storm coincides with the sunrise. It happens every autumn a few times, but the intense drama of the lighting always takes me by surprise, like Friday morning, when I forgot to take my DSLR along for the morning dog walk near Heaton Bay. So I ended up shooting the dawn light with my iPhone. A year ago, that would have stressed me out and I would have fretted about not having my “real” camera. Not so much anymore. Instead, I just enjoyed playing with the iPhone, tilting the lens toward and away from the light to try and get an optimal exposure and appreciating the way the sensor reacts to those subtle changes.
