Digital Camera Features
Selecting the right lens for the kind of picture you want to take is important. Your options include using a macro lenses for close-up shots of small objects, wide-angle lenses to get more in the shot and zoom lenses to make distant objects appear closer. Many compact digital cameras are equipped with a 3x optical zoom lens, while some offer as much as 50x optical zoom and more. DSLR cameras have detachable lens mounts, allowing you to choose the lens that's most appropriate for the shot.
Most digital cameras have at least a 10-megapixel sensor. Photo quality is determined in part by the size of the sensor. Lens quality is another factor that affects photo quality.
Viewfinder and LCD +
Most digital cameras have an LCD screen for composing shots and viewing the image afterwards. Some, particularly the bigger models, also have a viewfinder, which you raise close to your eye to look through. One of the main benefit of viewfinders is they allow you to shoot in bright sunlight that would wash out the image on the LCD screen.
Digital cameras are considered "high-drain" electronic devices, so rechargeable lithium ion batteries are a good option.
Manual Focus +
In general, higher-end digital cameras will offer both a manual focus and auto-focus option. Manual operation allows you to focus on exactly what you want in the frame. Manual focus is also useful for adding special effects to your photos.
Shooting Modes +
To capture the perfect shot, you may need a particular camera setting. Fortunately, you can often select a built-in shooting mode that meets your needs. The different shooting modes found on most digital cameras include auto, portrait, landscape, macro, night, sports and panorama. Check your camera’s instructions to learn how different modes work better in different types of situations.
Most digital cameras today shoot not only still pictures but also full-motion video. The better ones offer full HD video, so you can capture life in stunning detail. The clear advantage here is that it eliminates the need for a second device if you plan on shooting pictures and video.
Digital vs. Optical Zoom +
There are two types of zoom available on digital cameras. Digital zoom first captures an image and then uses digital manipulation to enlarge a section of it. In optical zoom, a telephoto lens enlarges the image before the picture is taken. Depending on your desired result, each method can add subtle nuance to your photo.
Face & Blink Detection +
Many digital camera models offer advanced features such as face detection and blink detection. Face-detection helps improve the camera's focus on the important part of the subject, typically the face. Blink detection provides a warning when people in the frame are blinking, giving you the chance to reshoot the picture.
Wireless Connectivity +
Most digital cameras today are Wi-Fi-enabled, allowing them to connect wirelessly with other Wi-Fi-enabled devices. This way you can send photos to your smartphone, tablet or laptop. You can also use the wireless feature to connect to the Internet and upload pictures to your favourite social websites.
GPS stands for global positioning system. A GPS-enabled digital camera can record directly the location where an image was taken directly into the photo. This is helpful when trying to recall places, times and events.
Shutter Speed +
The shutter-speed feature helps controls how much light reaches the camera's image sensor. The more light that reaches the sensor, the brighter the picture will be. A faster shutter speed reduces the amount of light exposure, while a slower shutter speed increases the amount. This function is essential for shooting in very bright or very dark environments.
A camera's aperture is the opening through which light travels to reach the image sensor. Aperture is measured in f-stops. The lower the f-stop number, the more light is allowed to pass through, while the higher the f-stop, the less light is allowed through. This function also assists shooting in bright vs. dark settings.
In digital photography, the ISO setting determines the camera's sensitivity to light. The higher the number, the less light is needed to take a photo that is correctly exposed — meaning not too dark or too light. On a sunny day an ISO setting of 50 or 100 is fine. But in a dark room, for example, your camera needs some help. You can either decrease the shutter speed to give your camera has more time to take in light, or you can increase the ISO.
