What are the pixels of a camera for?

Pixels, for a camera, are the smallest photosensitive units in the photosensitive element. Each photosensitive unit is responsible for receiving and processing the light and shadow it receives from the lens, and generates a photo we see after processing.
For a photosensitive element (CMOS) of the same size, such as a full-frame camera, the size of the photosensitive element is about 35.7×23.8mm. On a sensor of this size, the higher the pixel, the more photosensitive units, and each photosensitive unit The smaller the occupied area, the smaller the light and shadow area that needs to be processed.
The impact of this change is as follows:
1. The captured details are richer
Because there are more photosensitive units, the recognition of light, shadow and color is more detailed. For example, for example, one photosensitive unit originally recognized a certain color as blue, but now there are 3 units that recognize black, blue, and blue-gray. , the same unit area has two more photosensitive elements, which will make our photos more detailed.View more:Best camera for beginners in 2022
2. Larger space for secondary composition
The higher the pixel of the camera, the larger the pixels of the photos taken. For some messy backgrounds that have to be photographed due to the influence of the environment during shooting, we can deal with them by cropping without too much loss of image quality . For example, a 60-megapixel photo can be cropped into a 20-megapixel photo, but the cutting space for a 20-megapixel photo is very limited.
This is of great help to friends who are beginners in photography. We often use secondary composition to crop the photos we take.Recommended reading:7 Best 3 Point Slinger for Camera in 2022
3. Printing is more flexible
The photos taken by high-pixel cameras can be printed in a larger size. This should be easy to understand. The same pixel density, the higher the total pixels, the larger the size that can be printed, and the quality will not be affected.
The above are the typical advantages of high pixels. As for the higher the pixels, the clearer the picture quality is. This depends on the comprehensive performance of the lens and CMOS, not just the pixels. At present, there is no doubt about high-end mirrorless cameras. It must be that the higher the pixels, the clearer the picture quality, because the current CMOS technology of the camera supports about 60 million pixels. There is no problem at all.
