Quality of a digital camera's image depends upon which factor?

Question

a) Megapixel
b) Internal software and hardware of camera (i.e manufacturer)
c) Or any thing u suggest best

Please select any of these option for me to select a good digital camera. thank u

Answer 1

The size of the sensor as well as the number of megapixels affects image quality. The lens used also affects image quality.

Clever marketing has led many to believe that the more megapixels the better. Unfortunately, that isn't always true. If you pack 12 megapixels into a sensor that previously held 6 megapixels problems arise. For an in-depth explanation of this go to shutterbug.com and do a Search for High Resolution Digicams by Peter K. Burian. It was in the Nov. 2007 issue of Shutterbug Magazine.

How the camera is supported when an exposure is made also affects image quality. For the best results mount your camera on a tripod.

If maximum quality is your goal then a DSLR with 10 to 12 megapixels should be your camera of choice.

Answer 2

The higher the megapixel does make the pictutre better typically. But, the stability software a camera may have along with the internal processor speed/quality can make a difference. If you are looking for a really small camera, you will probably want a higher megapixel. If you are not worried about size, you can select a slightly larger camera that has stabalization software/hardware that would not require as large of a megapixel. My canon G3 is only a 4 megapixel that takes awesome pictures but it is kind of large. I bought another smaller canon (i cant remember the model) that can fit into my pocket and its a 6 megapixel. The pictures do not look as good as they do on the large camera!! good luck -Alan

Answer 3

Here are a couple of responses to your question:

a) Megapixel. At least 5 megapixels according to Consumer Reports. Any higher, invites longer shutter delays due to time it takes to write the image onto a memory device;
b) Speed of the writing device and speed of the actual memory card especially when taking multiple hi-speed pictures;
c) Availability of image stabilization during low light and slow shutter speeds;
d) ASA rating for poor lighting conditions. Upwards to 800 is sufficient, any rating higher than that invites picture noise.
e) Aperture of the normal lense, 2.8 is better than 3.5, etc.
f) Who makes the lens? Leica, Carl Zeiss, Zuiko, Rikkor, Nikon, Canon are major quality lense makers.

Good luck!
