Just a note on the JPG format. While it is popular and takes less space,
it is what is called a lossy compressed format. It will lose something
off its initial quality each time the image is saved, rename, or moved.
TIFF files are one of the preferred formats for digital achieving in either
uncompressed or lossless compression.
Here is a good resource in more detail
