Understanding Digital Cameras
Capturing beautiful moments and​ making them accessible quickly is​ no longer a​ rich man's forte .​
Most of​ us have access to​ our memorable moments in​ just a​ click away .​
Digital cameras save you a​ lot of​ time .​
Once the​ photo has been taken, you can just download those images in​ a​ computer and​ make them accessible on the​ net in​ various ways .​
Digital cameras record and​ store photographic images in​ digital format .​
Capturing pictures is​ usually accomplished by use of​ a​ photo sensor, using a​ charged couple device (CCD.) After transferring the​ pictures to​ your computer, you can edit and​ save them in​ a​ compact disc or​ hard drive.
With digital cameras you can instantly seize the​ picture you would love to​ keep forever .​
Delete unwanted pictures easily .​
No hassle of​ buying films .​
You don't have to​ print every picture; you have complete control of​ the​ final print after editing on computer .​
No worries of​ negatives getting spoiled or​ lost .​
You can store many images without having to​ change or​ buy films .​
There are many brands of​ digital cameras available in​ the​ market today .​
These include: Sony, Canon, Olympus, Nikon, Kodak, Minolta and​ Fuji .​
These are a​ few famous brands worldwide .​
Even basic digital camera models have plenty of​ features, levels and​ menus .​
This makes it​ difficult for​ beginners to​ select the​ right camera meeting their needs .​
Digital cameras are available in​ all price ranges depending on the​ amount of​ features they have .​
Before you start comparing the​ features you should decide for​ what purpose you would like to​ use your digital camera .​
The best way to​ start your search is​ to​ log on to​ the​ net and​ visit all the​ sites that offer feature and​ price comparisons for​ different types and​ brands of​ digital cameras.
Almost all digital cameras today have live-preview functionality, where a​ screen is​ provided in​ the​ camera to​ see the​ preview of​ the​ image that you just clicked .​
The most commonly compared feature in​ digital cameras is​ the​ mega pixel .​
This means the​ amount of​ pixels in​ millions .​
Therefore, a​ four mega pixel camera would have four million pixels .​
The other important features to​ compare include optical and​ digital zoom capacity; connectivity with other devices such as​ computer, printer, etc.; the​ internal storage space as​ well as​ compatibility with external storage devices; memory cards; batteries; and​ image file formats .​
Many digital cameras offer connectivity through USB port, FireWire port, USB PTP mode, Bluetooth, Wi-Fi, etc .​
These days, many cameras are offering PictBridge mode that allows direct printing from the​ digital camera without the​ mediation of​ a​ computer .​
Though all cameras have some amount of​ internal memory, external memory cards are required to​ save more pictures .​
These include Micro Drives or​ Compact Flash memory cards that are generally used for​ high-end professional cameras .​
Memory Stick by Sony is​ a​ proprietary flash memory card .​
SD/MMC, Mini SD and​ Micro SD cards are the​ ones used mostly for​ commercial digital cameras .​
If you are an​ amateur photographer, then you should select a​ camera with automatic settings and​ features .​
This will help you in​ getting the​ right pictures based on the​ amount of​ light and​ scenes without too much effort .​
But if​ you are looking for​ a​ professional camera then you should pick the​ one that allows you to​ select all shooting modes manually .​
There are many shooting modes available in​ the​ latest models of​ digital cameras including landscape, portrait, panorama, action settings, night mode, beach mode, snow mode, and​ sunset/sunrise modes.
The common formats in​ which you can take out the​ image output include JPEG, TIFF, DNG, etc .​
For videos, the​ most common formats are AVI, DV, MPEG, MOV, WMV, ASF, and​ MP4.
