Subject: Re: [Leica] slide vs. print film for PhotoCD

Velvia is 160/80 lpmm, Super G 100 is 125/63 lpmm, and Kodak 
Royal Gold 25 is 200/80 lpmm.  Velvia is the slide film with the 
highest tested resolution, and Royal Gold 25 (AKA Ektar 25) is the
highest resolving print film.  

I never knew this.....I always was taught that slide film would present the
better quality enlagement and scan.  For these reasons I put up with the
inconvenience of slides.  I would be head over heels if I found a print film
that scanned better and enlarged better than Velvia!  I think Royal Gold 
25 may do it.......I'll get my test PhotoCD of scanned RG 25 negs back
on Monday afternoon.

If both are stored under optimum conditions, how much longer than 
negatives do slides last?
