While I don't pretend to have much technical knowledge at all, I did
notice that the quality of the image was much higher with PDF than JPG
in this particular instance. Why that happened, I haven't a clue, but if
that's not the case generally, it's well worth noting -- thanks. Thanks
also for the tips on how to convert PDF to JPG. Also, thanks for the
info on how to properly take a tombstone rubbing. As I mentioned, we
were caught somewhat unprepared for the necessity of doing the rubbing
and as a result had few options (and very limited knowledge) available
to us. Next time we'll know better!

Dear Laurie and all,
I believe some of the below comments were published before, but it is worth repeating some tips about what Laurie wrote:
1. PDF is definitely NOT a graphical image format. It was conceived by Adobe for electronic documents transmission. So it shouldn't be used to produce digital images. As compared to the JPG format, which IS a graphical standard for digital images, JPG compresses much better then PDF - comparatively, the ratio could be as high as 20:1 - and it is also universally reproducible on monitors, printers, the Web browsers and other computer devices of the kind.
2. PDF pictures and pages CAN BE converted into JPG format quite easily. There are two methods: (a) to use a PDF to JPG converting software and (b) -> this is the easiest and most expedient way - using a screen capture program or the PC's standard "Control-Print Screen" capture feature.
3. As a matter of fact, one can amplify an image saved in PDF by using this trick. All one has to do is to zoom-in inside the PDF Reader program and then capture the screen.
One last comment about rubbing letters on a tombstone. It is well known that this procedure will damage the stone, mainly if using coal (burnt stick or similar). However, if the stone is very old and wearied, and getting a picture of the engraving is more important then conserving the stone, the best "rubbing" method is to fill in the engravings with shaving foam. After taking the picture, the foam can be washed away. And this method delivers excellent photographic results.
