Preparation for Figure 9.19 was similar to that for Figure 9.1but a black carbon paper was used to transfer the perspective drawing.

The value study in charcoal disclosed that ihe most dramatic effect could be obtained by Ihe selection of a light source from above and to the left, giving definite light and dark sides to the building and providing a dark form of low adjoining buildings asa base. It was decided to make the tower darkest at the top and at the edges next to the sky.

Detail in this project was almost eliminated because of the smallness of scale. A general impression was sought, rather than a detailed rendering. The dark shadow in the foreground (from a building assumed to be behind and lo the left of the spectator) and the two scale figures were included in the position in order to push the building into the mid-distance.

Shading. This rendering was made by the smudge process; that is, strokes were applied and then smudged with a chamois as follows:

1. A general gray value was given to the shade side of the office building by hatching with the side of a BB pencil in several directions. Then each portion of this side was in turn masked with 8l/¿- X 1 1-inch pad paper and rubbed with a clean chamois (see Figure 9.17, sketch d). The spandrels were then given the same treatment in order to make them darker than the glass areas. They were shaded with a BB pencil.

2. The general light-colored, grayed tone on the light side of Ihe building was applied by hatching, care being taken to darken the left upper edge.

3. The spandrel areas were then lightened by masking each spandrel with 8 Vfe- X 11-inch pad paper and erasing with a piece of kneaded eraser. The strokes in the erasing process were made from the left- and right-hand edges of the spandrels.

4. The small dark openings in the center of the light side of the building were applied with a BB pencil, and each opening was made separately in order to obtain gradation.

5. The upper left-hand section of the light side of the building tower was then darkened by hatching softly with the side of a B pencil.

6. Shadows cast by spandrels were introduced by the use of a T square and a loosely held B pencil. Reverse shadows on the shade side were cast by the same method.

7. The dark areas at the top of the tower were next indicated by hatching, using clean, short strokes with a B pencil. Shadows were added in the same manner.

8. After the entire office building had been rendered, rough edges (places where hatching had gotten into the sky area) were cleaned with a kneaded eraser by masking the building with pad paper and then erasing in a wiping motion away from the building.

9. The low surrounding buildings were next rendered by hatching in several directions with the side of a BB pencil, masking with pad paper, and then rubbing with a chamois. After the general tones had been put in, cornices, window, canopy, and other details were drawn by hatching with the point of a BB pencil. The low building at the right of the picture was indicated in the same way.

10. The values on the street were put in unevenly to avoid monotony, and a dark shadow cast by a building to the left of and behind the spectator was added in the immediate foreground.

1 1. Scale figures were distributed throughout the picture to draw the eye to theentranceof the building. Likeail values, these are dark in the foreground and lighter in the background, and were drawn with B, BB, and BBB pencils.
