reviews on 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.
