This was a bonehead mistake of mine, I didn't even think about page
size. Changing the document to an A1 solves this problem.

I don't understand this. If I open the two documents in photoshop and
do an image size it shows the exact same number of pixels.
My question is thus:
(1) I saved the image as a jpg and then (2) opened that jpg and
inserted into the pdf.
If I bypass step (1) then the pdf is 10 times as large, why is that?
