Digital cameras are technological devices that convert photos into digital data. Most modern digital cameras have the ability to record video or audio in addition to still images.
Many modern digital cameras feature USB connections for instant file sharing. It was common for early cameras to connect to the PC’s serial port. The Universal Serial Bus (USB) is the standard, however some devices also support Firewire and Bluetooth. Some cameras have Wi-Fi capabilities that allow them to connect wirelessly to a computer network.
If you’re on the market for a new digital camera, take these ten factors into account: –
The cost of a camera can range from a few hundred dollars to more than ten thousand for a top-tier professional model. One may be had for less than $600 and offer decent resolution and features. More advanced models, suitable for serious amateurs, can be purchased for $600–$2000.
Second, the camera’s resolution should be at least 1-2 megapixels in order to print high-quality color images at the common film sizes of 4 by 6 inches and 5 by 7 inches. You’ll need a higher resolution of roughly 2-3 megapixels if you plan on printing as large as 8″x10″.
Third, the viewfinder: entry-level digital cameras use an optical viewfinder, while higher-end models have an LCD screen (Liquid Crystal Display). Consider getting one that has an LCD screen. Check out any of Kodak’s digital cameras, as they offer great screens.
Fourth, most cameras have either a fixed focus or an autofocus, both of which are fine for the typical digital camera user. Everything from from a few feet to infinity is sharp when using a lens that doesn’t focus. The only time this becomes an issue is when getting too near for a photo. Focusing on whatever is in the exact center of the viewfinder is a breeze thanks to autofocus.
5: Memory If you plan on taking a lot of photos or videos, you should verify that the camera’s included memory card is sufficient. It probably won’t be, therefore you should research how much a new “good” capacity memory card, battery, etc. will set you back for that model.
Look for a camera that saves images in “CCD raw mode,” or without any compression, if you’re after the best image quality.
As for number seven, batteries, you should definitely invest in a camera that is compatible with rechargeable ones. Battery options include Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), and Lithium Ion (Li-ion) (Li-ion or LiOn). Find out what sorts of batteries your camera takes in advance.
Eighth, economize on electricity by switching to a camera that can be charged with a wall outlet.
Those looking for the fastest transfer rates should keep a watch out for cameras and card readers with FireWire as their interface of choice.
Invaluable for presentations is the ability to output video. If you would like to do this, look for a camera with a video-output terminal. It allows you to display your photographs on a TV or projector.
