There is an old rhyme which goes:
Tell not thy aged parent's parent
To extract the embryo juices of the bird by suction,
That kind old lady can that feat enact
Regardless of thy kind instruction.
I am aware of how jpegs work but this has absolutely nothing to do with my
practice in making platinum prints as I use 'film', a concept which may be
before your time.
Incidentally, the phenomenon you often describe as 'loosy' should in fact be
'lossy' . 'Loosy' sounds rather like an unpleasant form of diarrhoea.
