Did You Know?
A bitmap image is stored as a grid of tiny squares called pixels. Each pixel stores a number representing its colour.
Resolution is the number of pixels in the image. More pixels can show more detail, but require more storage space.
Colour depth is the number of bits used for each pixel. A 1-bit image can only store 2 colours, while an 8-bit image can store 256 different colours.
Image files also need metadata: extra information about the file, such as width, height, colour depth and sometimes the date created, camera settings or author.
