Despite this being a somewhat boring topic, after today’s lecture, I have realised the importance lighting in videos.
In terms of video production, light is the key process in creating the video since all type of cameras needs light to be able to process an image (light detection through the CCD).
However thinking beyond the camera, using light in specific ways can produce several effects which can help tell the story to the audience, examples such as:
- Intensity (brightness/strength of the outputting light)
- Quality (direct light often used for emphasis of actors/objects and diffused light, often used to control shadows)
- Light contrast (contrast between light and dark tones, can be used for emphasis or to give a powerful impact)
- Light direction (depending on use, it can create a mystery type theme, or silhouettes )
- Colour of the light (to create a specific impact or to support the original light source)
Often in video production, there is more than one light source in out scene, whether it being a lamp in the background or an off shot external light they all serve a purpose if used correctly. An important effect quite often used is called the 3 Point Lighting Technique.
This consists of 3 lights used on one object at the same time, A Key light (main light source for a scene, creates occlusions), a Fill light (usually opposite the key light to control the intensity of shadows created by the key light) and Back light (usually opposite both lights, it shows more illumination for the surroundings giving a more natural lighting scene, it also outlines the object/actor from behind). If this technique is used correctly, it can create a very strong scene to immerse the audience.
