On sunny days open shade will give you the look of a cloudy bright day, but you have a lot less options as to where you can shoot.
You can find open shade on the side of a building opposite the sun, or under a bunch of trees. Cat was on the west side of a building when the sun was in the east.
Christian was on the north side of a building with a nice graffiti wall when the sun was high in the southern sky.
Our house has a south facing covered porch which provides nice open shade on sunny days. Kristina (top) and Jael (above) were both photographed on our front porch.
If you can find a place with plenty of trees they will give you open shade.
