Filters to Improve Your Lighting:

Los filtros permiten agregar o reducir ciertos colores de luz, mientras que otros se utilizan para controlar la cantidad de luz que pasa a través del lente. Otros brindan un toque creativo o distorsión, según el estilo de la escena. A continuación, se muestran algunos de los filtros más comunes que se utilizan para las cámaras.

Color Filters: There are times when the light conditions cannot be changed. For example, the blue color of sunlight is strong when shooting outdoors at noon. You can add a warming filter (usually a #81 or #85 filter) that will decrease the blue and bring up the yellow tones. If you are shooting indoors with orange incandescent lighting, you can make the image more balanced by adding a blue cooling filter (usually a #80 or #82). The key is to remember that you warm the image by adding a yellow filter, and cool the image by adding a blue filter.

Ultra-violet (UV) filter: At times, a camera will not be able to see through things like smoke or dust and will produce a cloudy image. Ultraviolet filters help remove the haze and allow natural colors to appear richer and less cloudy. Sometimes referred to as Skylight filters, they help to improve the color of skin tones on bright days.

Polarizing filters: Similar to a UV filter, a polarizing filter helps to control the direction of the light rays entering the camera. This helps decrease the amount of light glare or reflection that is bouncing around the scene. Often designed to rotate around the lens, polarizing filters can be turned for the best results based on the camera’s position.

Filtro de densidad neutra: Uno de los filtros más comunes para utilizar en escenas con mucha luz solar es un filtro de densidad neutra. Este filtro reduce la cantidad total de luz que entra en la cámara. Ello se compensa al mejorar el rango de exposición de la cámara.

Special Effects filters: Though many filters change the luminance or chrominance of an image, some can create optical effects at the camera. All of these special effects can be seen more clearly as the light level increases.

– Star filters create a streaking or star effect when pointed at bright lights.

- Difusión filtros blur the edges in the images, especially when there is strong backlighting en the scene.

– Vignette filters make the outer edges of the frame appear blurry or out of focus.
