Electronic camera features change greatly from model to model. Before you buy, consider the following features, which are included on most digital cameras.
Exposure modes
Most
digital cameras, including SLRs, are heavily automated, with features like automated exposure control, which manages the shutter speed and aperture according to the available light. In that mode, the camera generally handles setting ISO and autofocus too. But there are more program modes that allow you to control specific settings, including shutter priority, aperture priority, as well as special scene modes.
Resolution
This term refers back to the sharpness, or detail, of a picture. The higher the number of pixels, the higher the resolutions. You can determined the resolution you need by determining what you wish to do with these footage. Picture size is measured by how many pixels make up an image and is measured by horizontal by vertical resolution, as in 1280 x 960. The makers break this down to about five main different classes of resolutions, expressed in mega pixels.
Memory
Digital cameras store pictures as info files instead of on film. The size of your memory determines the amount of photos you can take before downloading the photographs to a P. C. , at which time you can go back and fill the memory up with new footage. Most cameras come with only eight megabytes ( MB ) of memory, which for a two or three mega pixel camera could be only ten to forty footage.
Flash Type
Available on nearly every electronic camera, a flash ( or strobe ) allows you to illuminate subjects through a short burst of light. Almost all have auto-flash modes, a setting that may automatically fire a flash whenever the camera senses there's not enough illumination for a correct exposure.
Burst Mode
Known as fast Fire and continuous Shooting mode. Generally, there is a 1-2 second time lag between pressing the shutter button and a picture being taken with a digital camera. Then there is a 2-30 2nd recovery time before the camera is in a position to take another photo. With the Burst Mode feature you can take several photos in a row. This useful for taking shots in motion,eg kids playing or sports events.
Optical Zoom
There are two types of zoom lenses, digital and optical. Digital zoom simply enlarges the picture without adding any clearness of detail. A similar thing can be done with modifying and cropping software. Optical zoom will do what you actually desire ; add detail and sharpness. The larger the lens ( 2x, 3x, which is standard, 4x, etc. ) the more picture taking flexibleness you have.
More Features of Digital Cameras
Compression - this process shrinks the file size of a photo. Uncompressed snaps are more clear, the files are great and need huge amounts of memory. JPEG format compresses the files, permitting you to store more, save, download, and e-mail footage at a quicker rate. For general use, JPEG is fine.
Power Source -
digital cameras are voracious eaters of batteries. They use either a rechargeable battery pack or conventional batteries, usually two - four double A. Some have an AC adapter also. For chargeable batteries, which you need unless you truly like to buy a lot of batteries, and often , NIMH batteries can be charged up to 1000 times, while Lithium Ion batteries may also be charged up to one thousand times and last twice as long as NIMHs.
Lens - lens length will determine what proportion of a scene will fit into a picture. Some cameras have fixed-focus lenses, which are preset to focus at a certain range. These photos generally focus between a wide angle lens and standard range. Many cameras have auto focus, which pick an item in the center of the viewfinder around which to focus.
Focus and Exposure - This electronic camera feature attempts to discover a face in the image to set focus, exposure, and color balance so that faces appear in focus and well exposed. When we have tried it, we discovered that it generally worked well. In some cameras, you must turn on the feature. In others, it's enabled at the factory, but can be turned off.
LCD Screen - this screen will let you see what the photo will look like and, generally let you see what you have already taken and erase what you do not want. The screens use lots of power, but are very desirable for revising purposes. Some cameras will let you display multiple photographs on the LCD screen at one, generally 9 or twelve at a time.
Self-Timer - this is an option that lets the paparazzo be included in the photo. Self-timers have a pre-set delay, generally giving you about 10 seconds to run into the shot.
