Key light

The key light is the first and often the most important light that a photographer, cinematographer, lighting videographer, or other stage composer will use in a lighting setup; it is the main light on a subject.

Key light is used in the basic lighting of an object or subject in cinema. can be to the right or left of the camera. It cannot be in two places at the same time. It is positioned to form a 45 degree angle with the camera. It cannot be placed beyond 45 degrees, but can be placed below. 50-100 cm above the height of the camera is sufficient.

If it is set below this value, it will show longer, especially if the faces of the people are flattened. If it is increased above this value, it will show a flatter face if the person's face is long. a key light casts a shadow.

Key light

If the object has more than one shadow, another switch should be turned off, assuming it is a lamp. In high key lighting, the key light provides all or most of the light in the scene. In low key lighting, the key light provides much less of the total illumination.

In general (if the ambient light is not strong) it is a strong light. Our most important light is the key light, which makes the scene visible and simulates the solar task in nature.

There are many ways to light a scene and choose the lighting equipment to use. Some of those:

  •      Which elements in the scene are desired to be highlighted,
  •      From whose eyes or from what angle we see the scene,
  •      How the characters or items in the scene differ from each other,
  •      It is what emotion is wanted to be given by the hardness and color of the light.

When these are decided, the desired image and effect in terms of lighting can be obtained by choosing the technical lighting and equipment.
