Today in BTT01, we learned a lot of important things! First of all, there will be a test next Wednesday about Microsoft Word and Legal Rights (podcasting). A pixel is a very small blot on the screen short for Picture Element. We learned that there are different colors used for ink (cyan, magenta, and yellow), then the colors used for light or on the computer screen (red, green, blue). These six colors complement each other. For example you could get cyan by mixing green and blue together, and you could get blye by mixing cyan and magenta together. The more colors you have in light, the lighter your picture gets while the more colors you have in ink the darker your picture gets. Each color in light (red, green, and blue) can have 256 different shades or tones. So if you multiply 256 by 256 by 256, you would get around 16.7 million different color combinations! That means that each pixel has a piece of red, green, or blue in it (or none if you want a perfect color). If you wanted a perfect color, you would type in 255 for the color you wanted (because 0 is a level too) and then 0 for the other two. It is also good to note that if you put 0 for all three of your colors, you will get black. If you put 255 for all of your colors, then you will get white. If you have any equal levels in between (such as 78 for all three colors), then you will get a shade of gray. Also, colors are measured in the hexadecimal or Base 16 system. The values for this system are as follows: 1, 16, 256, 65536, etc. Since the computer would get confused if you were to write 10 in this sytem, we use the letters A-F to represent the numbers 10-15. So A stand fors 10, B stands for 11, C stands for 12, D stands for 13, E stands for 14, and F stands for 15. There is no need to have any other numbers after F, because then it becomes 16 again. The hexadecimal color is used as a code (for example 3F4B8E) for a certain color, and you can actually see the code in Adobe PhotoShop. Speaking of Adobe Photoshop, we learned how to use a neat function called the Eyedropper. This function turns your cursor into an eyedropper, from which you can see the colors used in a picture and see it's actual coding. This would be really neat to try on a scanned picture. Whew! That was a long post-Mohammad Signing Out.
