All about How Digital Images Work
A digital image is made of tiny squares called pixels, each with its own colour. The more pixels an image has, the sharper and more detailed it looks.
Zooming in on a photo often reveals the pixels.
Each pixel has its own colour, which is made by mixing red, green and blue light. When all the pixels are put together in a grid, they form a complete picture on the screen.
This is why a photo with more megapixels can be printed bigger without becoming blurry.
