With some idea of what range of brightness your camera can cope with, measure the dynamic range of various scenes.
Take five differently lit scenes, and within each, find and measure the brightest and darkest areas. Make sure the picture situation varies!!!
Make sure that one of the scenes has a very high dynamic range, and another has a low dynamic range, in other words, appears flat.
Other than this, there are no limits to the scenes you choose, because an important part of this exercise is exploration and discovery.
