问题                              Lighting Contrast
     Since the brightness range that the co]or film will record is less than that of black-and-white film, the user of Kodachrome and Kodacolor Film should avoid subjects in which there are extreme highlights and deep shadows unless the pictures are taken for that effect. Good detail should not be expected in both the highlights and shadows when the lighting contrast is extreme. For pictures of people outdoors, the full lighting produced by sunlight coming over the shoulder of the Photographer to strike the subject from the front will give the most satisfactory effect. Subject positions that produce side lighting and back lighting may give effective Kodachrome pictures if the camera side of the subject is well illuminated by open sky, or if reflectors are used to light the shaded areas. Exposure recommendations for such lightings must be followed closely. A white cloth, sheet of cardboard, or a projection screen are good reflectors for building up light in shaded areas when taking close-ups of people and pictures of flowers and other small objects. Kodacolor pictures require even more care in adding light to shaded areas when the subject position does not afford full front lighting.
     For pleasing effects in nearly all outdoor photographs, it is necessary to give careful consideration to the position of the sun. Pictures of people made during the middle of the day with the sun directly overhead are not pleasing because of the heavy shadows under the eyes, nose, and chin of the subject. During midmorning and midafternoon with the sun lower in the sky, excellent modeling and shadow effects are easily obtained. In some locations during winter, the sun is low enough in the sky during midday to afford good lighting. The angle of the sun is also important in making scenic and architectural photographs since their success depends largely upon shadows and texture.
     Correctly exposed Kodachrome and Kodacolor pictures made under conditions of a hazy sun, with soft shadows cast, are usually quite good because of the soft lighting. Kodachrome pictures property exposed on dull days, while somewhat bluish, are pleasing, which is usually not the case in black-and-white photography. [br] The best color pictures are taken when _________.
选项 A、the sun is directly overhead
B、the range of highlights and shadows is large
C、the sun is lower in the sky
D、black and white film is used
答案 C
解析 文中第二段提到“During midmorning and midafternoon with the sun lower in the sky, excellent modeling and shadow effects are easily obtained.”所以C项正确。
