What is the difference between JPEG (.jpg) and TIFF (.tif)?
JPEG is a compressed image. Depending on the compression ratio, the file size can be 1/10 to 1/5 of the same image in TIFF format. I will not get into the technical information about why JPEG can be small and efficient. However, the file size of JPEG depends on how many different color and how scatter the different color is. So, even though all images are at 6MegaPixel, but their file size can be very different. On the other hand, TIFF is an uncompressed file format. Therefore, the file size can be very large compare to JPEG (18MB vs. 3.5MB).
