Digital Technology 
    This section explores the technical components responsible for digital image quality.
Digital Camera Basics
Pixels and Beyond Cells and Pixels 
    In digital cameras the light-sensitive medium is a silicon chip covered with a regular pattern of very small light sensitive circuits.
Sensor Size 
    Consumer cameras use small sensors, only a few millimetres in each dimension, making the individual pixels very small.
Lens Quality and Storage 
    Lens quality also has an important influence on the image quality - there is little point in having a high-resolution digital conversion of an unsharp optical image.

Film Background 
    Color film photography is a technology rich in history and closely tied to the art world. Eastman Kodak popularized color photography after the introduction of Kodachrome slide film in 1935. Color print photography using 35mm film grew rapidly in 1961 after the introduction of Kodacolor II print film.
The Megapixel Myth 
    Forget the silly debate over pixel counts among digital cameras. There is little visible difference between cameras with seemingly different ratings. For instance, a 3MP camera pretty much looks the same as a 5MP camera.
What Kind of Camera?
What Kind of Camera? 
    Although there are many cameras, they fall into three main categories.
Types of Digital Cameras 
    Regardless of how digital cameras look, the market for them is roughly divided into three tiers with blurry lines separating cameras based mainly by image resolution, features, and of course, price.
The Two Classes of Digital Cameras 
    There are two completely different kinds of digital cameras: fixed lens and SLR.

What Is... Noise?
Noise 
    Just what is noise and how can we eliminate or minimize it?
Digital Photography Essentials "Noise" 
    Noise in digital cameras can be defined as anything visible in the captured image that was not present in the scene.
Digital Noise and ISO Control 
    All digital cameras have variable ISO settings that give the user greater (shooting) freedom.
