Standing floor is the line where the object and the ground agree. The base of the sleeve or the carton is locked to a continuous plane. There is no bright gap, and there is no second horizon running off at another angle.
The shadow belongs to that same light. One soft source from the side, a little fill so the dark face stays readable, and a contact shadow that is darkest at the base and falls one way. A glow painted under the object, with no plane for it to sit on, is a pedestal. It asks the viewer to believe in weight the drawing never built.
If you are showing a study and not a photograph from the floor, say so. A teaching drawing can be exact about the contact and still honest that it is a drawing.
How to check it
- The floor line should touch the base. A gap means the pack is hung in the frame.
- Every shadow, including the one inside a recess, should fall the same way.
- The horizon of the table should be one line, not a set of diagonals that never meet.
