Assignment due October 11th: Primary Colors

leave a comment »

This assignment keys off our look at how a camera sensor works, by combining red, green and blue colors.

For this assignment look for images that contain, one, two or three of these colors. My hope is that we’ll start opening our eyes and minds to the importance of color in our photographs. If you are not carrying your camera with you every day, now is a good time to start.

One question did come up about what are primary colors. Essentially RGB is additive and RYB is subtractive.

RYB (an abbreviation of red-yellow-blue) is a historical set of colors used in subtractive color mixing, and was once thought to be the set of primary colors. It is primarily used in art and design education, particularly painting.

For additive combination of colors, as in overlapping projected lights, CRT displays or most camera sensors, the primary colors normally used are red, green, and blue.

The RGB color model is an additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
