If it ever got below freezing in Cape Town, this early morning dew would be frost. However, it rarely gets below even 10C in the middle of winter, so all we get is heavy dew.
I tried to capture the colours of early morning sunlight reflected in the dew drops, but failed.
Afterwards I wondered if the blues and yellows I was seeing so clearly were maybe due to the refraction of light in my thick glasses!
But perhaps if you squint a little, you can see some colour in these spangles?
post script: Many places in SA do get well below freezing in winter, and get snow too. When I lived in Johannesburg, it was minus 8C one night, and the fountains froze in town!
