Even with some open shade, the midday sun at the South Bank Parklands (next to the Brisbane River) makes for difficult shooting.
Aside from the issues of dynamic range, there's the related problems of sunglasses. It's good that people are protecting their eyes, but they're hiding those eyes from my camera.
It's little use to ask someone to remove their sunglasses, because even if they agree, then they'll be dazzled by the light — and will squint. Again, hiding those eyes that are so good to catch in street portraits.
This all comes to mind because I spent a couple of hours at South Bank near midday.
