Lighting is really significant in film. Actually, lighting is the key element to create the cinematic effect of scenes. Undoubtedly, the basic usage of lighting is same with camera, which is allowed viewer able to see something, in other word, it light up the subject. Also, the lighting depicts the story, show the contrast, create the continuity and enhance the special emotion.
As Robin mentioned the lighting could be divide to several parts, which are direction, intensity and quality and color. Like we did in class, the Key light cannot change direction in different shots, because it will lead the problem of continuity. However, we could move the light a little forward or back to cooperate the position of camera. Generally, in filming process, the director will use fill light to make a better contrast of subject. The control ability of key light and fill light is so important, I hope I can try it and improve it in future works.
The quality of lighting mainly is talk about hard light and soft light. Hard light creates the obvious contrast of subject, it might show strong emotion in some time. And soft light largely and normally used in film to create natural shadow. In class exercise, Robin taught me a good way to adjust the quality of light. When we feel the light is too shard, we could use a white board to bounce light making it be more soft. This is really useful.
I really like the different color usage of lighting, I think it is perfect way to give a special emotion to environment and characters. For example, using the cool blue color to emphasize the isolated, lonely or high technical feeling, the yellow red color to create romantic and dubious feeling.
