If you're doing that (which I recommend), I set my camera to "raw +
jpeg", and then dump the raw files to DVD. That way, it doesn't matter
what happens to the jpegs as you can always re-create them.
If you've only got jpegs (why are you using a rubbish camera :-) then
just dump the original jpegs to DVD - that's why what Google do is so
bad - they compress it to upload it from your Android phone, and then
delete the original! AND THAT'S THE DEFAULT !!!
Cheers,
Wol
