Both amateur and professional photographers now are mostly purchasing digital cameras to meet their photography needs. Because digital cameras with new and improved features regularly are introduced to the marketplace, consumer should know how to compare the difference among the multiple cameras that are available. This section lists guidelines you should consider when purchasing a digital camera.
Type of Digital Camera:
Various types of digital cameras exist, including point-and-shoot cameras, field cameras, and studio cameras. Point-and-shoot cameras typically fit in your pocket and meet the needs of most general consumers. Field cameras, which often are used by photojournalists, are portable but flexible. Field cameras allow photographers to change lenses and use other attachments, and also are more customizable than point-and-shoot cameras. Studio cameras are used in photo studios and are stationary. These cameras give you the widest range of lenses and setting.
Many consumers mistakenly believe that the digital camera with the highest resolution is the best camera for their needs. A higher resolution increases quality and clarity of your photos, as well as the size at which you can print the photos before noticing degradation in quality. If you never plan to print photos larger than “8 X 10”, for example, you do not need a camera with a resolution greater than 5-megapixels. Many cameras available today advertise higher resolutions can use valuable storage space. Just because your camera can take a 10-megapixel photo does not mean that you always should set the resolution to 10 megapixels.
Size and Weight:
Digital cameras are available in various size and weight. Some people prefer smaller, lighter cameras because they are easier to transport and take up less space. Others prefer bulkier, heavier cameras because the weight helps steady them to take a clearer picture. Many digital cameras also include an image stabilization feature that reduces the possibility of a blurry picture if you move your hands slightly while taking the picture. Some also believe that heavier cameras are of better quality, although that seldom is true. When choosing a digital camera, practice taking pictures with it and select one that feels comfortable and natural.
When purchasing a digital camera, pay careful attention to the type of memory card the camera uses. Many use SD cards, some use xD Picture cards, and some use CompactFlash memory cards. Some memory cards are more expensive to replace than others, and some have a higher capacity than other cards. If you take a lot of pictures, purchase camera that supports a memory card with a higher storage capacity so that you can avoid carrying multiple memory cards. You also might consider purchasing a camera that uses a memory card that is compatible with your other mobile device.
Photo Editing Features:
Some digital cameras have integrated tools that allow you to edit photos directly from the camera. For instance, you may be able to crop photos, change the brightness, or remove red eye effects. Editing photos directly on the camera after taking them can save you from editing multiple photos at once when you transfer them to a computer. The photo editing capabilities available on digital cameras are limited when compared to photo editing programs, but in many cases they can edit a photo to your satisfaction.
LCD screens on digital cameras allow you to configure the settings, frame a shot before taking it, and preview photos after taking them. LCD screens vary by inches, so select a camera with a screen that does not require you to strain your eyes to view. This is especially important if the camera you are considering does not have a viewfinder, because you then will be required to use the display to frame your shots.
If you plan to take pictures of people or objects that require you to zoom in, select a digital camera that has a high optical zoom. An optical zoom enlarges the subject by adjusting the camera lens, whereas a digital zoom uses algorithms built into the camera to magnify images. Optical zooms, as opposed to digital zooms, often result in a higher quality photo. While a digital zoom might be capable of magnifying objects that are 100 feet away, the photo will suffer a loss of quality.
As with all other devices, locate a digital camera that does not exceed your budget. If you find a great camera that is available for more than you are willing to spend, consider locating a camera with slightly lower resolution, an alternate brand, or a smaller screen. Digital cameras can last well beyond five years if properly maintained, so consider this a longer-term investment that will create memories lasting you a lifetime.
Some digital cameras require replaceable alkaline or rechargeable batter4ies (often AA or AAA), and others have a rechargeable battery. Similar to batteries in portable media players, using disposable batteries in digital cameras can get expensive, and they may last as long as rechargeable battery packs. Digital camera battery life is not measured in hours; instead, it is measured in how many pictures can be taken on a single charge or set of batteries. Turning of the LCD Screen and flash when you take pictures can help to extend battery life.
Accessories that are available for digital cameras include carrying cases, extra batteries and battery chargers, and extra memory cards. Carrying cases can help protect your digital camera, especially while traveling, and the extra batteries and chargers can stay inside your carrying case so that they are readily available should you need them. Screen protectors can help protect the LCD screen on you digital camera.
