So you’ve just returned from the camera shop with all the information that you need more megapixels your camera. Your current compact camera has 8. 1 megapixel and the seller tells you that you need to upgrade to the 10 new ones. 1-megapixel model to really improve your pictures. Rubbish! Here’s why you do not need de.Parce that digital cameras are often classified according to their number of megapixels, the megapixel rating of a camera is often used as a measure of image quality. This is a totally wrong concept and myth. There are a number of factors that determine the quality of a megapixel camera and is really an insignificant part. 10. 1 megapixel compact camera with low price and 10. 1 megapixel digital SLR and dear to the Antipodes. For comparison, they mean nothing. If they served something so why such a big difference in their prices. The price difference between a compact and an SLR should immediately tell you that there are other factors to take into considération.Voici what really matters: 1. Quality of the lens caméraIl costs a lot of money to build a quality lens with high quality glass. If the device is cheap, it means the lens is cheap. Even if it had 36 million pixels in the quality of your image is going to mean. Camera manufacturers can not afford to put quality glass in a camera of bad quality. Even with digital SLRs that have interchangeable lenses, the difference between entry-level lenses and lens Pro is enormous, measured in thousands dollars.2. Quality camera construireLes parts that go into building a good quality digital camera costs a lot of money to develop and then the camera will cost more. The cost difference between plastic or aluminum and high quality magnesium alloy is large. This is more so with digital SLRs. When comparing how a shutter button or dial feels a entry level SLR, you will feel a considerable difference is still reflected in the prix.3. Quality of capteurComment manages your sensor light and noise that results depends on the quality and construction of the CCD or CMOS sensor and ISO rating. Try taking a picture with lots of shade and you will see that in the darkest parts of the image are patches of color and a more granular. Is the noise. The more expensive cameras will have much less noise, or sometimes no sound at all compared to the less expensive compact cameras. This degrades the image quality, even with a good objectif.4. Quality of processeurChaque device has a computer chip called the processor that supports the digital information received by the sensor and transforms them into an image. The way they are treated affects the speed and overall quality of the image. The more powerful and complex processor for the best image quality and of course plus the cost of the device. Again, the more megapixels processed by a processor of low quality will continue to provide an image of low qualité.Il is so easy to use one aspect of a camera to judge the quality of a camera and c ‘ is that manufacturers and sellers have done. It is much easier than to explain a number of complementary factors, but makes the explanation of a myth. We need almost quadruple the megapixels of a camera sensor to an obvious improvement. Even just doubling megapixels does give you a subtle change in quality. And this will again only really play a role if all other factors are also of augmenté.Alors, how do you know what to buy? The answer is of forums and review sites. See what reviewers have to say and then read the forums and hear what people who bought the camera, you can have dire.Utilisez your natural instincts and you’ll know when a person derives sales the dressing. No manufacturer can afford to sell high quality at low prices. This is why many manufacturers sell you a digital SLR lens comes as a kit with the camera and not a single high quality, reduce coûts.Ainsi, the bottom line, your instincts. When someone wants to sell you a BMW or a Mercedes at a price Suzuki alarm should sound.
