The focal length of the lens is the distance between the lens and the image sensor when the subject is in focus, usually stated in millimeters (e.g., 28 mm, 50 mm, or 100 mm). In the case of zoom lenses, both the minimum and maximum focal lengths are stated, for example 18–55 mm.

White balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo. Propercamera white balance has to take into account the "color temperature" of a light source, which refers to the relative warmth or coolness of white light.

Autofocus points are what the camera uses to focuson a subject. You'll probably first notice them when you press the shutter halfway. Many cameras will emit a "beep," and some of the AF points will light up (often in a red or green color) in the viewfinder or on the display screen

Exposure compensation is the control by which you temporarily adjust your camera's definition of what is "properly exposed". Put simpler, it's a way to force the camerato make your photos darker or brighter to the degree that you tell it
