The shutter is like a window shade behind the camera lens. When you take a picture, the shutter opens briefly to allow light to enter through the lens and strike the camera s image sensor. Shutter speed refers to how long the shutter remains open. The slower the shutter speed, the more light the sensor soaks up.

ISO ratings are used to indicate the light sensitivity of the image sensor. The higher the ISO number, the greater the light sensitivity and the less light is required to expose the image.
Create Bar Code In None
Using Barcode generation for Software Control to generate, create bar code image in Software applications.
Code 39 Extended Generator In None
Using Barcode generation for Software Control to generate, create Code 39 Full ASCII image in Software applications.
If you re used to working with autoexposure cameras, you may not be aware that being able to set aperture and shutter speed manually gives you creative control over more than just how light or dark your picture appears. Aperture affects depth of field, which is the range of distance in the picture that s in sharp focus. Shutter speed determines whether a moving subject appears frozen in time or blurred. Advanced cameras offer you the option of working in either autoexposure (AE) mode, in which the camera chooses the aperture size and shutter speed, or in manual mode, in which you make these decisions. As an alternative, many cameras offer semiautomatic modes called aperture-priority autoexposure and shutter-priority exposure. In these modes, you set one control (aperture or shutter speed) and the camera selects the other. Although you can sometimes persuade the autoexposure mechanism to select a particular f-stop or shutter speed upcoming chapters share the tricks you use to do so working with a camera that offers the option of manual exposure control makes it easier for you to implement your creative decisions. At the least, your next camera should offer one of the semi-automatic modes.

Using Barcode generation for Online Control to generate, create EAN 128 image in Online applications.
Scan Code 128C In Java
Using Barcode recognizer for Java Control to read, scan read, scan image in Java applications.
When you compose a picture, your creative choices are in part controlled by the focal length of the camera s lens. Focal length, which is measured in millimeters, is the distance between the optical center of the lens and the element that records the image in a film camera, the negative; in a digital camera, the image sensor. Focal length affects the angle of view and the size at which your subjects appear. At a short focal length, you can capture a wide area, but objects appear smaller and farther away. At a long focal length, the opposite is true you can capture a narrow area, and objects appear larger and closer. As an example, see Figure 1.1. I took both pictures from the same position, but I doubled the focal length for the second image.

Experienced photographers pay close attention to focal length when camera shopping because of the impact of this feature. Many people, though, aren t aware that you can t evaluate digital camera focal lengths on the same scale you use for a traditional camera lens. To explain this fully requires a lengthy lesson in camera optics, but here s FIGURE 1.1 A short focal length captures a wide view of a scene (left); a long the short story: The size focal length makes subjects appear larger and closer (right). of the recording element affects what the camera sees at a particular focal length, and image sensors are much smaller than film negatives. To capture the same image as a film camera, a digital camera needs a focal length about one-sixth as long. Further complicating the matter, digital camera manufacturers use a variety of sensor sizes, so there s no reliable formula for translating traditional focal lengths to digital. Instead, the digital industry has adopted the practice of stating camera focal lengths as 35mm film equivalents. Camera specs may read something like this: Focal length: 7.5mm, equivalent to 50mm with 35mm film. In photographic magazines, the abbreviation efl (for equivalent focal length) is sometimes used 50mm (efl), for example. Other resources, including this book, use the abbreviation equiv. However it s stated, this information tells you that the digital camera lens produces the same image you would get with a 50mm lens if you were shooting 35mm film the most widely used negative size in film photography. To sum up, if you re accustomed to judging lenses based on focal length, just ignore the digital focal lengths and look for the 35mm equivalency numbers. If you re new to the whole focal length thing, the following list offers a few guidelines:
