The No. (Switch to a lighter yellow filter for outdoors portraits, like the Wratten No. 9 (which is considered by some to be a medium-yellow filter and was formerly designated the K3), emphasizes reds and orange tones, which is excellent for brilliant sunsets in black and white, but not for portraits since it causes facial blemishes and freckles to stand out. It gives a natural look - normal tonal rendition - on black and white film to the sky, sunsets, distant landscapes, foliage, outdoors portraits against the sky and water scenes, and is ideal for architectural stone, sand and wood when they are illuminated by direct sunlight or a blue sky.Ī deep yellow filter like the Wratten No. ![]() 8 yellow filter attached to the lens for much, if not most, of their photography. Many photographers who shoot black and white film have the No. If a single filter could be considered the "standard" filter for black and white work, it would be this yellow filter. This light to medium-yellow filter is also sometimes called a Y2 filter, and has a filter factor of 2, which means it requires a one-stop increase in exposure. The most-popular density of yellow filter is the Wratten No. A light yellow filter will render the sky in a more natural-looking shade of gray. For example, when shooting a scene with clouds in it using a deep yellow filter, the clouds stand out as bright white against a dark sky. The greater the density, the greater the contrast between blue and white objects in a scene. Like most filters, the yellow filter is available in various densities. Snow scenes improve with a yellow filter. It is a good filter to use when doing underwater black and white photography. A yellow filter absorbs UV and is useful in reducing haze, particularly in aerial or mountain photography.

The denser the filter, the more the exposure must be increased to compensate for the light being absorbed by the filter. Keep in mind that the intensity of the effect is controlled by both the density of the color filter in use and the subject's color saturation.Įxposure is affected by the amount of filtration. Our section entitled How colored filters work explains why this happens. The rule to remember is: Use the same color filter to lighten that color, and the complementary (or opposite) color filter to darken it. This means that a blue ball photographed through a blue filter will show up as almost white in the final image, but if the blue ball was to be photographed through a yellow filter (which is the complementary color for blue), it would render the ball as almost black. ![]() Visit Light and its color for a thorough explanation, but for now, all you have to know is that a complementary color is one of a pair of primary or secondary colors that are in opposition to each other on a color wheel. What is a complementary color? Essentially, it's any color's opposite color. At the same time, it reduces the amount of light of the filter's complementary color, which will appear in a darker gray tone. The photographic reproduction of any color can be altered by filters.Ī colored filter causes more light of the filter’s color to strike the film or your digital camera's sensor, making that color appear as a lighter gray than it would without the filter.
