Exposure basics 1

Exposure is very important for every photograph. When you master exposure you can get image effects that create mood and allow you to get creative when you process the image later. This portaait was made with natural light and aided by edge blurring later in software. If you break an image down to channels you can see the components that combine to form a full color image. A digital image is recorded through various color filters- R(red), G(green) and B(blue). The image processors then integrates these signals to form the full color image. In digital you can have a profund influence over how color is recorded and the brightness of these colors. You could think of the exposure system as a seesaw in which you want to achieve balance using exposure to mediate between the sensitivity of the sensor and the brightness values in the scene. The goal of exposure techniques is to capture all the brilliance of color and light from the scene as in this early morning shot.
