When light strikes a metallic object, it can reflect back onto any nearby object in an unusual way. Normally, light hitting a primary and secondary object gives varying degrees of light, shadow and cast shadows, but reflective light also happens under these circumstances – and I'll show you how to draw this in your artwork.
01. Place your objects in light
Select interesting objects – such as this highly polished metallic teapot and a ceramic vase – and place them with light catching one side so you can carefully observe the highly lit and shadowed areas. Then draw basic shapes with a charcoal pencil, trying to represent these reasonably accurately, although adjustments can be made later.
02. Get shading
Shade the object in direct light first – here the ceramic pot to the left – observing the deeper and lighter values. Then move on to shade the object in its shadow – here the metallic object. It was important to really concentrate on the depth of the cast shadow from the ceramic pot as it struck the left side of the metallic one, here. The deepening of the shadow to the right of the metallic pot follows conventional rules of light and shadow.
03. Add some shadows
The objects appear to be almost floating in space at this stage, so need grounding. Shade the shadows cast by the objects as they fall to the right across the table top, thus sitting the objects on a solid base.
04. Blend and soften
Using a charcoal eraser, rub out sections of reflections and – here we rubbed out from the already shaded right side of the vase, where the light was reflected back from the teapot. You can see how this is of secondary importance compared to the other highlighted area.
Finally, blend some areas using your finger to soften the transition of tonal variances on the vase for effect.
