Digital Cameras Features (IV)Hide
Auto-Bracketing
This is a useful command that sets the camera to capture a series of photos of the same scene or subject. Each shot is set at a slightly different exposure setting. Three frames is usual with most cameras, but some allow five-frame bracketing. Usually cameras auto-bracket by varying f-stops, while some high-end models let you choose auto-bracketing by f-stop or shutter speed and only a small percentage of digital cameras allow you to auto-bracket white balance as well as exposure.

Best-Shot Selector
This is a simple feature that allows the camera to capture four or nine shots almost instantaneously. Each frame of course has a slightly different exposure or white balance setting. You'll find this feature to be similar to auto-bracketing with the exception being that you get to choose which images you want to save; the others are discarded automatically. Sometimes the best exposed images are automatically selected from the camera's best-shot selector intelligence.

Other image controls:
White Balance

This refers to how things will look under various lighting conditions. If the white of the image appear to be correct, it is safe to assume that the rest of the colors in your photo will appear like what you see in your real-world scene or subject. Regardless of the light source, all digital cameras have the ability to adjust the color of your picture so that white always looks white. Higher end cameras give you the option to set white balance manually or choose a preset light source which can result in more accurate color.

Program Mode
Special types of photographs require different setting. These presets are designed to prepare your camera to take those special types of photographs automatically. Examples of these settings can include settings for night scenes, sports and action subjects, portraits, sepia/black-and-white images, etc.

Panorama
This a popular feature that you can have a lot of fun with. This allows you to photograph a sequence of images, each from a slightly different position and stitch them together into a single photograph. There are some digital cameras that provide overlapping guides in the LCD viewfinder to assist you in getting better panoramas.


Metadata
Your digital camera automatically saves technical information every time you shoot a picture. This can be displayed during playback or when you edit your image on the computer. Technical information provided ranges from standard dates and times, to more extensive information found on higher-end models such as exposure settings, modes such as exposure settings, ect.
