For this exercise we have to produce three photographs with contrasting light conditions and show that we have the correct exposure settings to have as much details as possible in the darkest and brightest areas of the photograph.
I was thinking how to work in this exercise and decided to take photos in Auto and save the file without editing and then try to set the correct exposure, shoot in RAW and then edit to get as much details in the darkest and brightest areas.
In the first example below, we can see more details in the sky, in the dark areas of the building and the branches of the trees etc.
In the second example, we have more details in the mountains, in the water, in the grey tones of the building (bottom left).
In the last example, we can see more details below the tree and the leaves of the trees.
