As we walked from the Art Gallery through The Domain to the Sydney Hospital to get a coffee, I was taken by this storm building up in the west, behind the CBD. So, I took the shot which I have posted second. But it wasn't what I saw. Because, said my daughter, you metered off the buildings. Try metering off the clouds.
So I did, and got the shot which I have posted first. This is what I saw. Both shots vary only in shutter speed. They are F8, ISO=400, with a Focal Length of 60mm. The bottom shot has a shutter speed of 1/1250, whereas the top shot has a s/s of 1/3200.
By the time we got there, the coffee shop was shut.
