What is the difference between spotlight and floodlight?

1、 What is a spotlight？

The so-called spotlight is a type of lamp that uses a reflector or spotlight lens to produce visible light. Therefore, a spotlight is also known as a reflector. A spotlight is a relatively simple type of lamp that has a high intensity of illumination and a narrow range of illumination. The light source belongs to a central light source, and we often use it in some photography studios In indoor studios or some relatively large shopping malls, shops, and other places, among these numerous spotlights, the most popular one is LED spotlights.

2、 The difference between spotlight and floodlight

Spotlight is a hard light projected from a distance, with normal color temperature and pure surface color, which can achieve good visual color effects. It is a type of lamp that uses a spotlight or reflector to gather light. This type of lamp has high luminous intensity, high brightness, and belongs to the hard light type. It can form obvious shadows on the surface of objects and serves as the "protagonist" in lighting fixtures. It is often used as the main light and contour light for characters or scenes.

Spotlights can project highly directional beams of light. It can produce bright highlights and sharp lines, with dark shadows. In most cases, people always use a combination of floodlights and spotlights, which not only ensures a soft overall lighting layout, but also makes the outline of the strong light area clear, clear, and bright.

The light angle of a spotlight must not exceed 120 degrees, otherwise the light will not be the effect of a spotlight. It is best to choose a light exhibition angle below 90 degrees. The blur value of light shadows is generally set to 8.

An omni light is a point light source that can illuminate evenly in all directions. Its illumination range can be adjusted arbitrarily, and it is represented as a Regular octahedron icon in the scene. Omni lights are the most widely used light source in renderings, and standard omni lights are used to illuminate the entire scene. Multiple floodlights can be applied in the scene to produce good results. The light bulb used for shooting can be installed into a large reflective umbrella for use as a high brightness diffuse light source. Although it is indispensable for indoor lighting in the shed, it can also be considered one of the good lighting sources for general amateur indoor photography.

Floodlights are not spotlights, projection lights, or spotlights. Floodlights produce highly diffuse, directionless light instead of a clearly defined beam of light, resulting in soft and transparent shadows. When used for object illumination, the speed of lighting reduction is much slower than when using spot lights. Some floodlights even have very slow lighting reduction, appearing as a light source that does not produce shadows. Spotlights project a directional and well-defined beam of light, illuminating a specific area.
