How to buy a Digital Camera?
If you want buy digital camera. Few features you must consider:
How many mega pixel camera do you need?
2 megapixels or less
* This is typically found on smaller, inexpensive cameras or cameras in combination with other devices (such as cellphones or PDAs).
* It will be hard to make a high-quality print of any size, but these are just fine for e-mailing photos or posting photos for a personal web site.
* I wouldn’t recommend it for family portraits or if you really need a nice-looking print.
3 megapixels
* This is actually a good compromise between picture quality and low price for most casual photographers.
* You can print lovely 4×6 images, decent 5×7s and, depending on the camera, might even knock out a good 6×9 or 8×10.
4 megapixels
* You’re getting nicer. These images make practically photo-lab quality 4×6s, and great 5×7s and 6×9s.
* You can print a nice 8×10.
5 megapixels
* Hello, enlargements! This will produce beautiful 8×10s, and even a nice 11×14.
* Now you are getting closer to professional photographer levels, and the quality shows it.
6 megapixels and up
* Wonderful image quality, but high price tags. You can print large photos, even 11×14 or perhaps more, with satisfying results.
* There are some high-megapixel cameras coming out with lower price tags than most, but they usually have very few features.
* Unless megapixels are the only thing you care about (it shouldn’t be), don’t get a camera that sounds outrageously inexpensive for its megapixel range.
