When it comes to purchasing a digital camera, we must look at two aspects that will be essential to achieve the results we expect in our photographs, these are the megapixels (millions of pixels, or points of image) resolution offering, and optics.
The megapixels are important because while in the traditional cameras impresses a negative light that keeps the image in digital, a CCD sensor captures the image, which will be of higher quality as much megapixel resolution takes the sensor. Such data indicate the size to which it can print without loss of quality. In addition, the resulting color will have more nuances, the size of the printed photo may be higher and the potential for increased elaborate.
From 2 megapixel prints are available in a size of 10 x 15 cm with a decent quality, always using all realize that the benefits of the camera. This last point is one of the practices that must be improved, and that we must look first to give priority, if the image quality of the photographs or how much you want to save. In this case, if what preponderamos is the quality we have to configure the camera with the highest resolution image for the highest quality and the use of all the megapixels are used for a good image at the time to bring them to paper. Instead, we must lower the quality of revolution if we take the greatest possible memory space to store a lot of photos. In this case despenderá also the memory capacity of the card.
Professional photographers agree advise at least 3 megapixels for printing in a size of 10 x 15 centimetres to bring a good quality. The resolution suitable for printing a photograph with results similar to analogue photography in different formats of paper, is 240 pixels per inch at least.
Finally, it is worth doing a good clarification on the megapixels. It is possible that some vendors ofrescan offers digital cameras with a significant number of megapixels. We must be vigilant and determined whether this is interpolated megapixels or troops.
What is the difference? The megapixel interpolated are calculated by a computer program that invented the missing pixels. This provides no quality to the final outcome of the image and should not pay attention to this characteristic of the camera. Interpolation is a way to increase the size of the image, doubling the pixels, which are not 3-megapixel interpolated 3 megapixel real, but part of those pixels have been copied from others that it is real.
In conclusion, we can say that more megapixels does not mean better, only if you want to make big enlargements. To get the greatest advantage to the digital camera in this regard, it must be determined that it has manual controls, and if you have an optical zoom important. Most have 3X, which is good for fans looking for a good photograph.
