PART 2: LESSON 2 - SHADING

TIME: Allow 40min

Aim: To introduce reflected light and its effect on shadows and shading. To develop the use of shading for a textural effect.

Materials: The sketch pad, HB and 4B pencil, eraser

Allow five minutes to for the quick sketch test. Two minutes to do and three to mark. Swap, display and title if necessary.

a) Without using the ruler (or any other straight edge) prepare the page with margin and add the freehand boxes as shown previously.

While the students are thus occupied hand out these prepared theory sheets.

Sitting in the garden I asked a person if the shadow cast by a tree would be lighter on a sunny day, than it would, at a similar time, on a cloudy day.
'Does it really matter?' he shrugged, as he poured himself another glass of my most expensive imported red.
'That depends.' I replied, 'one day you might want to paint a shadow.'

'The grisaille legacy' .......
'I met a man of black and white who had sadly lost his way.
Wringing his hands, he said to me, "but all I see is grey".'

If a cup was placed in a spotlight the shadow it cast would be as black as the surrounding darkenss while the shading on the cup should move from a grey at the 'turning point' to a similar blackness.

However, if there was some other light in the room the 'black' shadow would look out of place - as shown above. The reason for this is that in our normal life we mostly don't live under spotlights. Usually, there are many sources of 'reflected' light around us. In a room or outside our shadows are rarely completely black as they are modified by the 'general lightness' of the day - or the room.
