cityscape – overcast / exposure to the city

I find that the sky brothers show method lacks 2 big levels … I'm back from 2 weeks in Europe and I've measured mostly from the sky and most of my clichés are underexposed …

Where should we measure when it is cloudy or when it is a cityscape? Most of my buildings are underexposed if I measure the sky, and if I detect the buildings, I get a white veil for the sky.

A tip from sky brothers on this one? 🙂
