Observing involves noticing the basic shapes, proportions and values of objects rather than thinking of them as “buildings”, “trees” or “people”. Once you have an understanding of the principles and have trained yourself to observe, it is then only a matter of telling your hand to draw what your eye sees, not what your mind thinks the subject should look like.
