Color Addition/ Subtraction Photo.

Before: (RGB lights)       

 After: Cyan Filter

After: Yellow filter

After: Magenta Filter

                Filters are used to absorb certain primary colors (RGB) of light and allow any left over primary colors (RGB) to be transmitted. When these primary colors hit a colored filter (CYM), certain primary colors appear, but some cannot be seen. As shown, when RGB hits a Cyan filter, only blue and green appear (transmitted), but  red is being absorbed, so you cannot see it very well. Next, RGB is shined on a yellow filter, but this time, just Red and Green are being transmitted, and blue is being absorbed. Lastly, to prove the color addition/ subtraction model, I used a magenta filter. Red and blue are transmitted, so they are visible, but green is absorbed, and not visible.
