2a. If you were in a photography darkroom with a red light, and were wearing a green shirt, what would your shirt look like? Why?
- Red and green are complimentary colors. This means that these two colors are opposite of each other on the color wheel (enchantedlearning.com/crafts/Colormixing.shtml). In a dark room with a red light, my normally green shirt would look black. This is because the color green absorbs the color red, and the combination of those two colors displays the color black. Therefore, if I looked down at my shirt, it would look black. This method of color mixture is subtractive.
2b. The yellow filter we played with in class is a very light yellow. How would a dark yellow filter be different, i.e. what colors would be missing or added?
- The yellow we used in class was very bright, usually amplifying the other colors and make them stand out more. Yellow will lighten semi-dark to dark colors while also changing the tone (https://images-na.ssl-images-amazon.com/images/I/51ynmFpn1YL.pdf). This is because the color has high saturation and high brightness values (https://www.quora.com/Why-is-yellow-seen-as-brighter-than-other-primary-colors). Using a dark yellow filter would do the opposite to most colors, making them seem dimmer when applying the filter over them. Using a darker yellow will make purple seem even more dark, almost a black instead of a gray. Colors that will appear will just be the darker versions of the one that the lighter yellow filter made. For example, a darker yellow filter would make a darker green, or a darker blue, instead of amplifying it.
2c. Search the web to find a red/blue 3D picture. Attach it with your answer and explain in your own words how the 3D effect works.
- When looking at the picture displayed below with 3D glasses (chromatically opposite colors, red and blue), it creates the illusion that the shark is popping out at you, past the screen you are looking at. When looking at a 3-Dimensional image through 3D glasses, your brain uses a technique called stereoscopy to create the illusion of depth. In my own words, I would say that 3D effects work with the contrasting red and blue, it affects your eyes and brain, playing a trick on them and making the image seem like it is right in front of you.
