Secondly, filters for color films

Colors appear natural in color films if photographed so that the appropriate film is used with the appropriate light conditions. For example, if we used a positive color film to obtain colored slides of the daylight type with daylight or electronic flash, it would give us correct natural colors. But if we use it with the light of fluorescent lamps, it will give us a chip that has a strong tinge of green or indigo, and in order to obtain natural colors, it is necessary to use a special filter called (F-DL), i.e. from fluorescent light to daylight, and this filter has a color that tends to violet like the color of salmon

For artistic purposes, the photographer may wish to give his image a yellow or orange tinge to give it more warmth, or a blue tinge to give it a sense of coldness. In this case, the photographer uses filters. It is necessary to think about the image before taking it and draw it in the imagination of the photographer, and after that he searches for the necessary means to achieve his prior vision.

What was previously mentioned in white film filters also applies to these filters

And black are:

1 - Change the response of the film to different colors - we need to compensate the exposure by means of the filter

Kodak has divided optical filters used with color films into three groups:

Kodak Color Conversion F filters: These enable the photographer to use film with illumination that is not originally prepared for it. For example, a movie
Daylight can be used with tungsten light (3200 Kelvin) using filter No. (80A), which is light blue in color.

2- Kodak Color Balancing F filters: This is a lighter degree than the previous filters, as it returns the balance to the light that has changed slightly from the standard light modified by the film. For example, daylight film when shooting at sunset gives an orange tinge. This smear can be removed if the photographer so desires by using a very light blue balance filter. Filter No. (82) and there are four grades (A, B, C, D) with orange rays.

- Kodak Color Compensating F filters: These are used to correct the light if it is completely abnormal from what the films were prepared for. One of the types of these filters has already been mentioned, which is the (F-DL) filter for photography in fluorescent light. This group of filters is also used when printing color films to remove color smears that may appear on them. This series is called (CC filters). There is a complete set of them in several densities. They are usually sold together in a box for use when enlarging negative color films.

In order to facilitate the process of choosing the appropriate filter for the appropriate film, you should draw the following drawing, and all you have to do is connect a straight line between the type of film and the type of lighting, and you will find that the line passes through a specific filter that can fix the colors to natural colors
