Megapixels have become a topic of debate since digital cameras, photo equipment manufacturers and photographers themselves have become popular, always wondering how much this data really influences the final result of photography. Better the quality of the photos. Manufacturers, mainly, always sold their products emphasizing the amount of these pixels as if they were the main quality of the cameras. Photographers, especially amateurs and beginners, ended up believing and spending more on megapixels without really knowing if they were related to image quality. Fortunately, this myth has gradually broken and now we know that, although important, the number of megapixels is not synonymous with image quality. There are even those who say that an exaggerated amount of this data can even decrease the quality of the photos and not improve.
The maximum number of megapixels offered by a camera is only reached when photos are taken with the highest size and highest quality, this number corresponds to the size of the photo and the capture of details. For the computer to do this with a sensor the size of a 10MP digital camera, for example, it will have to make the pixels in the image very small and this results in a lower light absorption capacity. When this happens, the photo can be very large, but without quality or noise, even if the camera is in a low ISO, it should be remembered that this reasoning evaluates only technical problems and not the routine and use of the camera by the photographer, it is necessary to align the technical details with the photographer’s lens daily.
- What few people know is that the maximum PP number for a camera is not fixed and can change depending on the photo that is taken.
- As mentioned above.
- The maximum number of megapixels is used for the largest photo size option.
- And you can take photos like this without losing clarity.
- But it will depend more on the quality of your camera’s sensor than any other specificity of the equipment.
In order not to increase the actual amount of megapixels and still be able to take large images, some camera manufacturers use the interpolation technique. This technique, instead of actually increasing the amount of MP in an image, zooms out the pixels and uses algorithms to calculate the area around them, thus filling the empty space with similar colors. When a photo has few details and only one dominant color, interpolation does not damage quality as much, but this technique can create a flaw in images in more detail, so it is recommended to always use the actual megapixels. .
Photographers are increasingly learning that the number of MPs is not as related to image quality because it depends on several other determinants, such as sensor size. Camera lens and manual settings are also factors that influence photo quality without megapixels themselves. A 6MP camera for amateur use, for example, achieves quality if it has a good sensor. For professional use that does not require large image magnifications, a 10 MP camera is sufficient.
It is true that digital SLR cameras with many megapixels tend to increase the noise in the images. But that doesn’t mean they’re worse than the rest either. When you consider that for professional use a 10 MP camera is ideal, it assumes that cameras with more than that do not have the same lens. When a photo taken with a camera of more than 10 MP, which was made to be enlarged, is seen up close or on the computer, for example, the noises are even more evident. In fact, the more megapixels the photo has, the bigger it must be to have quality. This type of camera is best used when used to take photos for billboards, billboards, and banners, for example. In this way, the noise is minimized. When no such magnification is needed, it is ideal to use a smaller size adjustment, or use size reduction, which is to reduce the photo area. This can be done in an image editor and can reduce the amount of noise in the image.
It’s very difficult to take sides in the world of photography, either way, because the best team will depend on how you use it, this won’t do any good if you buy a very expensive camera at very advanced, for example, if you plan to use the images just to post on social networks. That said, for amateur and professional photographers who don’t need to enlarge their images, ideally investing in equipment under 12 megapixels.
