I unfortunately missed this week where we were looking at tone. But that doesn’t mean I didn’t do anything. This was our homework where we had to shade sphere using light sources from different angles and different medium like pencil/pen/conte.
I got some example of how to shade from online and from a book I have “Drawing a Complete Guide” by Giovanni Civardi, it had some diagrams explaining how light interacts with the object to create the shadow and shows how the tonality changes going from the light sources and even some examples on how to place shadow on the plane.
