Although this is a picture of last year's spring dance showcase, I witnessed a lot of physics relating to this year's dance showcase. Before every show, we have at least one dress rehearsal. Mrs. O always says we have dress rehearsals because the lighting guy is going to watch our rehearsal. I've never really thought about why he needs to come watch our rehearsal until this year. I never really thought the lighting was a huge factor in our show, but I have realized without it the show is a lot duller. Through our studies on color, I have learned that by combining the primary colors of light, red, green, and blue, other colors, magenta, yellow, and cyan, can be created. In this picture, the background is magenta which is the combination of red and blue lights. At the NBC, I noticed that in order to light up the background, they put lights in the back of the backdrop. The lights shining from the front of the stage are used to illuminate our costumes. When we were rehearsing our dance, our costumes that are usually a dark blue appeared to be more greenish, which was caused by the lighting. Also I noticed that people with red hair became very illuminated probably because red light was shining on them.
