Bitmap

Raster Image (Bitmap): A digital image format composed entirely of a fixed grid of individual squares called pixels. Every pixel is assigned a distinct color and brightness value, which combine to form the final picture. This is the native format produced by mirrorless camera sensors during digitization. Because a raster image relies on a set grid of pixels, it is resolution-dependent. When you scan a photograph or document, you lock it into a specific pixel dimension; resizing or zooming in past that original capture size will eventually reveal the blocky squares of the grid, unlike vector formats which can scale infinitely.
