Pronounce it kind of like the man's name Maury with emphasis on the 1st syllable and a "-ay" on the end instead of " -ee".

Best I can do in American English.

That might not be moire' btw. Could be caused by screening, as in screening for print reproduction for magazines. Since I can't see the original, I dunno. If it is, there's a fix for that in your scanner, and in some versions of PS, known as "de-screen".

Turning the negative sounds like a brilliant fix if it works, and it may. Most "fixes", like gaussian blur simply blur it out of existence which can be very counterproductive if you want a sharp picture. Heck even "de-screen" simply blurs it a little in my experience.
