The camera sensor in the Mavic Air 2 is a 48MP sensor, and the drone can capture 48MP photos, but capturing at 12MP provides the best results. We mentioned pixel-binning in the article, that is where multiple pixels on the camera sensor are treated as one pixel to produce the final image. Camera sensors work by capturing light on the pixels, the more light you can capture on the pixel, the more accurate it will depict the colors it was exposed to. Since this has to happen in a flash (pun intended,) there is limited light exposed to each pixel on the sensor. By pixel binning, you are taking the average of four different pixels, and can computationally add values together from the four, to produce a more accurate color value. This is all done in the software, which takes educated guesses at what the best image should look like, but with teams like Google and DJI working on the concept, it's proven very effective and destined to get better.
