John,

Could you describe colour aliasing.  I can't find the term in the
literature I have.  I know that aliasing is about how the transition
between adjacent contrasting areas of an image is managed.  I can't
understand how the concept relates to the way that the colours of an
image are managed.  Of course the two concepts may be completely
separate and the common word is a red-herring.

Anthony Farr

Albano,
I really appreciate what you're doing.  Would I be asking too much
if I suggested that you separate the print films and the slide films?

No, it's not too much. Maybe I'll do it (I didn't because I'm not an
expert, and I don't know every film out there, and didn't wanted to
mistake)

That's exactly why I asked: I don't know which ones are slide and which are
print films.

If I usually just want to get a picture into my computer for web, email, or
other use is there any benefit in using slide film versus print film?

Richard Klein asked:

It depends.   Mostly it depends on your scanner.

If all you have is a medium-resolution flatbed scanner (under 600dpi)
then your best choice is to scan prints.  If you have a high-resolution
scanner with a transparency adapter, or if you have a film/negative
scanner, you have more options.

Negatives have a lower density range than slide films (especially
high-saturation slide films like Velvia), so they are easier to
scan.   They also capture a wider range of intensities, and so you
are less likely to have burned-out highlights or featurelesss areas
of shadow.  But these benefits don't come without drawbacks - the
contrast compression results in less midrange detail, and even the
best orange mask removal can cause colour aliasing artifacts and/or
a slight colour cast at the extreme ends of the intensity range.

Certainly a difference can be cost.  In some areas slides are cheaper and
others prints are cheaper.  One way that I hold down cost is to use negative
film and just have it processed but not printed.  Since I am scanning
anyway, C-41 process costs me US $2.29 per roll and E-6 costs me $5.99.
Usually print film is 1-2 dollars cheaper per roll.  So for me, cost is a
big difference.  Also, the quality of scanner can be important.  The higher
contrast of the slide can be more demanding to scan.
