mega-pixels make a better pic?

Question

Is it worth buying a 7/8 megapixel ? does make a better quality picture? can you notice that on the computer?

Answer 1

There are multiple contributing factors to "quality" in photographs.

More megapixels capture detail with smaller pixels, but our eyes cannot see the difference unless the image is magnified on a computer screen, or printed in a big enlargement. So buy more megapixels if you want to print in large sizes, or if you want to crop out parts of pics and enlarge them.

Other things that contribute to quality are:

. Lens clarity, evenness and size. Poor lenses can distort shapes or limit light gathering.

. Color sensing capability and size of the sensor

. Accuracy of the focus mechanism, especially autofocus

. Accuracy of the exposure mechanism

. Brightness and light dispersal ability of the flash

. And so on...

Sometimes cameras with higher MP come bundled with better other components too.

Find a camera in your price range. Then go to a store and see how it feels in your hands. Then see if its size and features fit with what you expect to do with it. If it seems like "The One", go on the internet and find some reviews of that camera.

Pro reviews are written by pros with high expectations. Don't let small differences distract you. Only eliminate one if strong negative statements are made. Most digicams from good brands will give satisfactory service. So concentrate on features that fit what you need.

Good Luck

Not always. The quality of the picture depends also on the technologies that the camera incorporates and for what kinds of photos are going to use the camera. If you'll use it to get some photos for a site, or an Internet post/ blog/etc., a basic resolution of 640x480 should suffice. If you wanna print the photos, you should go to a 4-5 mega pixel camera, for printing in a 10x15 centimeters image. From what I understand you want to go for a 7/8 Mp camera. From what I know that is used for large scale prints, or for post capture editing ( the image has a very good quality so it allows you to edit it with photo software, whereas from a camera with a smaller resolution, the edited images would become blurry.
Now we get to the type of light sensor that the camera uses. This makes the real difference between a good photo, and a real crappy one. The ordinary sensors are ones like:VGA, CMOS, CCD, CCD-HAT, etc. The 2 most important ones are CMOS(Complementary Metal Oxide Semiconductor) and CCD( Charged Coupled Device). The CMOS is used on a large scale because its production costs are very low, but its light processing quality even lower :). That has changed in the present, and SLR models use , ironically, CMOS sensors ( Nikon D2X, 12,4 Mp for professional use). So they have improved this type of sensor beyond its limits. If you really want a steady cam , one which you could use many years from now look up some cameras with the Foveon X3 sensor, they really are top of the line. Also if you decide to buy a camera with Super-CCD you should have in mind that this sensors 1Mp is equivalent with 1,5Mp of an ordinary CCD.
This is the secret to the perfect digital photograph: the sensor. Be sure the camera has a good LCD display. Don't get fooled by the indoors lighting, take the camera outside for a sec. Why? Because many cameras seem to have a good display under artificial light but when you take it outside the display goes blank and you can't distinguish anything on it. Make sure to buy a 1 GB memory card, these 7/8 Mp (Mega pixel) puppies don't give you any room to spare.
The bottom line : get a Foveon X3 if you have the cash if not stick with a SLR camera with CMOS sensor ( SLR refers to pros) as long as you want a camera with this much power. You could check smaller cameras lets say from 5 Mp up. The 5-6 Mp's are quite cheap comparing with the 7-8 Mp's.
I hope I've helped you even a little bit. Check the display under normal lighting!
Cheers!

Answer 3

Higher the Mega pixel and the optical zoom (and not the digital zoom), better the picture. Go for the Sony Cybershot series, they are the best. Yes with high resolution cams really make better quality and you can notice it when you view on your computer.

Answer 4

Yes better picture, the more the mega pixels the better I think. But consider the cost, what kind of pictures you are taking, sometimes you can do to much for what you need.

Answer 5

NO, NO, and NO!!!!!!!! Try to find a camera with at least 4 megapixels. Don't waist your money on a 7 or 8.

Answer 6

You won't see any difference on the computer. The only time you will is when making very large enlargements. The files they make can be very large and consume alot of space.

Answer 7

yes, and i recommend Nikon coolpix 3000 and above
