In order to imply form accurately, you need to draw the values you see instead of drawing what you think should be there. Place an egg on your kitchen counter and set up a light source. What are the darkest shadows? What is the lightest highlight? You should notice that in the center of the eggs shadow it seems lighter (much like the illustration below) this is called “reflected light”. This is caused by light shining on your counter and bouncing back into the shadow area. Although reflected light might seem very bright, it only appears so because of the contrast of the dark shadow surrounding it. Reflected light will never be as light as the light part! Paying attention to all these subtle details you see in the value changes is what will bring realism to your drawing. Try drawing the egg on your counter; use pencil and go nice and slow to avoid a scribbled look. Do not ever smudge to fade values- only the gradual lifting of your pencil.
