Every year the manufacturers of cameras and smartphones that come even to take photos at night always argue about the next model or type of camera with more megapixels than the previous one , the new resolutions can make your current model seem discontinued.
So if you got a camera with a few megapixels a while ago, you would like to have a new one with more megapixels, however, does it really mean anything? Does having more megapixels equate to better photo quality , or is it the result of well-planned marketing?
Megapixels in a camera
Basically speaking, a single megapixel is equal to approximately one million pixels in a photo Canon specializes in this, If you know or know the width and height in pixels of an image created by your camera, it is easy to calculate how many megapixels the camera acquires. camera, in this sense, simply multiply around six hundred and forty by four hundred and eighty to obtain a total of three hundred thousand pixels.
There are several reasons why you might want to buy a camera with a higher resolution in megapixels, the most prudent thing is to cut it, sometimes what you want to see in the lower part of the corners is not usually captured , if the photograph is cropped minimally, it is possible to observe different but better than if you left it unedited.
It could be said that the main advantage of having a camera with more megapixels is that it manages to get extra space when doing some kind of editing about the cutouts of the photos.
However, how much space is required if you want to double the size of the image , which would be much more than enough space to edit photos and still have a large image than usual on the device. it would be for a six-by-four print, up to four megapixels are achieved.
These are extremely tiny numbers so the brands and the market, the new arrival of more technology continues to expand the megapixels, it takes a reason to convince consumers that the next model to be launched on the market is going to have a huge improvement , and the best way to do this is to grow steadily as camera and device brands innovate new sensors annually.
The optimal megapixels for photography
The megapixels are transformable and sell a lot, they improved primitive black and white photography and allowed photographers to make works of art comparable to large professional industry however megapixels are not a real reason to change an old model instead it is better to focus In a kind of image you want and consider the limitations of the model you have purchased .
What really matters is the size of a camera’s image sensor is the main determinant of photo quality and the larger the sensor area, the greater the potential to produce high-quality digital images.
Equally important is the size of the actual photosites in the sensor that collects the imaging light, the larger the photosites, the more light they can assimilate and consequently the more image data they make available to the camera’s image processor. .
If you want to be able to crop images before printing to a certain size, then you need more megapixels, then if you learn image processing tools, like Photoshop, you can interpolate between pixels by adding more pixels to the image . Professional photography can also be achieved even with a smartphone .
The quality of a device is strongly influenced by the quality of the sensor, not just the megapixel resolution . In addition to this, the quality of the lenses you use play an essential role, and even more when you handle more megapixels, you can find a camera that could have fewer megapixels, but with a more optimized sensor and better lenses, you can get more clarity in the photo than with more pixels.
It must be taken into account that the more pixels, the smaller the size of the area in the sensor to capture the light such as capturing the sky or space, that is, the color corresponding to each pixel and, therefore, the greater the precision both in the sensor and the lenses, so much so that there have been cases with camera models of well-known brands whose megapixel resolutions were reduced when the following models were launched.
