ISO and Color Spaces

ISO is one of the easier concepts to understand when talking about exposure. Just like shutter speed, when you double the ISO, you double the sensor sensitivity, and vice versa. In the old days of film, you only had one ISO for the roll of film. With digital cameras, you can change the ISO with each picture.

Color spaces are models that define precise colors, some color spaces are larger than others. Color spaces are important for determining how your image will look, whether they are displayed on a screen, or printed out.
