●Episode

A brewery company distributes original pictures of seasonal gifts to each retail shop. It takes approximately one month for photographing. A problem was that difference in color tones on the pictures happened as time passed by due to deterioration of light source. Merits after introducing the artificial lightings are not only taking beautiful pictures but also being able to take pictures for a long time without deterioration.

A fishermen’ union conducted quality inspection of laver. While color of laver is black, violet/green/brown colors are mixed, and also graduations of tones or grossiness slightly differ. Furthermore, this difference of tones and grossiness affects class, grade, and of course, wholesales price. While the quality inspection is, usually, done by natural sunlight, it is carried out regardless of the night and day in harvest time.
