The digital photograph - already significantly compressed by the camera, as a bitmap of this size would be about 42k in size	Smaller than the original, and with a slight loss of clarity.	The blocks of colour and the spurious lines are the hallmarks of JPEG compression


GIF 256 colours 9053 bytes	GIF 8 colours 1849 bytes
Not noticeably worse colour than the original JPEG, but much larger	The colour is distorted and flattened, but the file is still bigger than 2 of the JPEGs
