A filter factor of 3X means that when daylight balanced light (full spectrum light centered on around 5500K) is passed through the filter, the total amount of light will be reduced by a factor of three (3), and one-third (one-third) of the original light will pass through the filter. One-third (1/3) the light is equivalent to one and two-thirds stops. But if that filter is a color filter, all wavelengths/colors of light will not be reduced by the same amount. If the filter is a neutral density filter, the brightness of all colors/wavelengths of light should be reduced by the same amount.

For an orange filter, orange light will be reduced by less than other colors of light. The further a color is from orange around the color wheel, the more light that color will be reduced.

Color filters are often used in monochrome (B&W) photography to enhance or reduce contrast between things that are different colors in the scene being photographed.

Since the filter is orange, orange light passing through the filter would be reduced by a lesser amount than other colors of light. Blue, which is directly across the color wheel from orange, will be reduced by the most amount.

• In portrait photography, an orange filter reduces the appearance of freckles and blemishes, giving the skin a healthy, smooth look.
• When photographing buildings and cityscapes, they give bricks a pleasing tone, and increase contrast between different materials to add depth and texture to the image.
• Similarly to red filters, they can be used to reduce the appearance of fog and haze, and to darken skies and emphasise clouds.

If there are orange and blue items in the scene that are the same brightness, without a filter they would both appear to be the same shade of gray in a monochrome (B&W) image of the scene.

By using an orange filter and increasing exposure to compensate for the filter factor, the orange object will appear to be lighter gray than before and the blue object will appear to be darker gray than before. If we used a blue filter, the opposite would happen. Our blue object would show up as lighter gray than the orange object.

With digital photography, the possibilities are much greater when saving raw image data. Different color filters can be applied during conversion from raw data to an image that will affect differently colored objects in the scene differently in terms of their tonal value (how dark or how bright a shade of gray they are).
