[Rob Oakes]

Hi Ruf,

You can modify the resolution at the time you export. It's under the PSF options at the bottom of the dialog.

But viewing the resulting PDF with 400 % on screen, I found the photos had too big pixels to be printed sharp. When I say "compress to 300 dpi", the resulting PDF has 44 MB, but the photos appear sharp enough. Or is that on-screen impression misleading?

(Haven't tried that yet, though there is a dialog which seems to do right that. But when I see that an untouched photo which appears in a smaller size on the page has merely 440 dpi, would it be worth to cut it down to 300 anyway?)
