The color by the present-day photo films is not 'true color'. This is because most people tend to prefer 'saturated color' rather than true color, especially in the highlight region. It has been shown that the preferred colors by most people are different not only from the true colors but also from the colors in mind. Possibly the preferred color will depend on the country and the culture. The color by the present-day photo film tends to reproduce the preferred color rather the true color.
Most people tend to believe the color by photo film to be the true color.
But it is a misunderstanding. True color technology has been established already, for example, in the case of the latest color copier. This case is simple. The original image is printed on paper . And the copy is printed on paper too.
