Luminosity vs. Chroma

This week we begin our in depth investigation of image processing. For the next few weeks we'll be looking into a variety of key terms and techniques. Our goal is achieve a better understanding of what goes on with our files when we process images and then to use this information towards individual pursuits.

Luminosity: the light-dark information in our image.
Chroma: the color information in our image.
Point Operation: changes made on the pixel level, such as using a paintbrush.
Neighborhood Operation: changes made to an entire image, such as using a blur filter.

Above you'll see an image plus the separation of the luminous and chroma information of the same image file, each layered over a neutral 50% grey background.
