幻灯教学是电化教学中普遍采用的简易手段。幻灯教学片的制作,及其大量翻拍成批生产(无论是实物的图象或是图表等资料的幻灯片),应以照相法最佳。众所周知,一般彩色片较黑白片的效果好。可是制作彩色片的设备和技术比较困难,在制作彩色片的条件不具备的情况下,能否使黑白胶片变为有色幻灯片呢?我们认为采用《藤氏兰法》和《彩显法》较能解决此问题。 Slide teaching is a simple method commonly used in teaching. Slide teaching film production, and a large number of remake of mass production (whether it is physical images or charts and other information on the slide), should be the best photographic method. As we all know, the general color film is better than the black and white film. However, the production of color film equipment and technology is more difficult in the production of color film conditions are not available, can make black and white film into a colored slide it? We think that the use of “vine Lan law” and “color method” is more able Solve this problem.
