Buying Digital Camera

With more and more models for digital cameras, it is not easy to find one which fits our requirements. However, here we can suggest some criteria for your selection
1.  How much PIXELS you need?
	Below table shows 200 – 300 pixels are already enough for 3R/4R photos. But, if you want to enlarge your photo to 8R, choice of 400 pixels is recommended. Nowadays the pixels of the digital cameras are up to 1000 whihc is enough to print a 12"x18" photo. Product Image Size (Inch) The Best Resolution (Pixels) Minimum Resolution (Pixels)   1.5"x2" ID Photo 8 pcs 1.5 x 2 450 x 600 270 x 360   2R 2.5 x 3.5 750 x 1050 450 x 630   3R 3.5 x 5 1050 x 1500 630 x 900   4D (4.5"x6") 4.5 x 6 1350 x 1800 810 x 1080   4R 4 x 6 1200 x 1800 720 x 1080   5R 5 x 7 1500 x 2100 900 x 1260   6R 6 x 8 1800 x 2400 1080 x 1440   8R 8 x 10 2400 x 3000 1440 x 1800   8F 8 x 12 2400 x 3600 1440 x 2160
2.  Light Focus or Digital Focus?
	The image taking under Digital focus is a bit distorted since the image has been enlarged to the exact size by internal digital focus function. While light focus is more stable to capture the highest quality of image. The range for light focus and the width of the camera is inter-related, so a balance design between them is very important.
3.  Which battery is more durable?
	It is very common to use Professional battery for digital camera. However, 2A battery is a good substitute. Though the former is more durable, 2A becomes more popular due to its increasing battery volume and shorter battery recharge.
4.   Which memory card is best?
	Compact Flash card, Memory Stick, SD Card, xD Card and Ultra Flash card are mostly used. Compact Flash and SD Card are lower in price while Memory Stick is relatively higher. About the memory size, most common of Compact Flash has 8G capacity. However Ultra Flash Card not only has large memory but also has fast saving speed, if your digital camera can be writen by high speed, Ultra Flash Card should be a good choice. xD is the smallest in terms of size.
