2. Description of the Related Art Conventionally, as a light source for photography, a tungsten bulb having a color temperature of 3200K (Kelvin) and a color temperature of 3 are used.
There are 400K photographic light bulbs and 6000K color temperature delight (strobe etc.). Here, the color temperature means the temperature (absolute temperature) of the perfect radiator when the chromaticity of the sample radiation matches the chromaticity of the perfect radiator. Has a color temperature of 6000K,
In the evening and morning, the color temperature is 3000 to 4000K. Delight, which is close to natural light, has a high color temperature and color rendering properties. Here, the color rendering refers to the appearance of the object color by illumination, and the color rendering index Ra indicating the degree of color rendering is determined by the reference light source when the perception of the object color illuminated by the light source is based on a prescribed condition. It is a numerical value that represents the degree of matching with the perception when illuminated with. For example, Ra is 100 when sunlight is used as the illumination light.

However, since the conventional strobe, which is a light source for delight photography, is a flash (flash) photography, unnecessary reflection may occur.
In addition, the illumination time is very short, and it is not possible to measure the shooting conditions in advance. On the other hand, photography is performed with a large-scale lighting equipment in which a large number and high density of tungsten light bulbs having a low color temperature are arranged. In this case, a special tungsten film must be used instead of the delighting film.
