The BMP format, or Bitmap, is one of the ways a camera can save captured images to a file. It is a raster format, meaning the image is described as a grid of individual color points, called pixels. A characteristic feature of the BMP format is that the data usually undergoes no compression, which is the process of reducing data size. In practice, this means that information about each individual pixel is stored. The resulting files are therefore very large in terms of data, but on the other hand, all image quality is preserved. This type of data storage is called lossless. Today, this format is rarely found in digital cameras, as it has been largely replaced by other formats.
