Week 4 - light

 

Week 4: Light and shadow

These images focus on implementing a range of light/dark values, shadows and cast shadows to illustrate shading and appear depth to a drawing.

The three 5 minute individual sketches focuses on shading using a pencil. The objects (pipes attached to a wall) were directly aimed by a light source, which the objects has displayed a range of dark/light values and casting a shadow. The two objects on the right were drawn using only one angled diagonal lines which the range of dark/light values were narrow making visibly difficult to picture the 3D shape, which the drawing looked very flat. To surpass this problem, the third sketch below was drawn using various shading techniques: hatching and cross hatching to enable use of wider range of dark and light values.
The third sketch is much improved compared to the other two, as shown there is more contrast between dark/light; highlights and very dark shadows, where light is completely blocked. However there are still few tints of shades missing in the drawing. This session has given me the importance of shading and how it is applied to a drawing to produce depth on paper.

Directed study

The three images displayed here are drawn using a pencil of one cubic object in different set of lighting environment: the first image at the top with just a torch in a dark room, the second without torch but with a room light, and the third image both torch and room light together, looking at different view point. These drawings illustrate the theory and demonstrate the techniques of shading: hatching and cross hatching, bringing a wide range of values of light and dark. We see the second image room light have less marking compared to the other two. The torch image has more variety of light and dark values. But more marks and variety of grey implemented on third image.
