How will a plane facing the light source generally look?

Brighter

The governing concept is the relationship between surface orientation and light. A plane that faces the light source receives more direct illumination than a plane turned away from it. In a drawing, this usually makes that plane appear lighter or brighter in value, although the exact appearance can also be affected by the material, reflected light, and the strength and direction of the source. Option B is therefore correct. Option A would normally describe a plane receiving less direct light or lying in shadow. Option C is impossible as a general result, because facing the light does not remove a surface from the image. Option D is also incorrect: every visible plane has some value, even if it is very light. Comparing the orientation of adjacent planes helps the artist model solid form convincingly.
