Hi,
I am a owner of a Nikon Coolscan V ED. The scan quality is a big step
forward compared to my former 2500 dpi HP photosmart S20, but I have a few
questions. I take my slides with a contax/zeiss 35mmSLR equipment using
elitechrome 100 film.
1) It seems to me that there is no improvement in detail resolution when I
compare 2500 dpi HPS20 scans with 4000 dpi nikon scams. Is it possible that
2500 dpi is already sufficient for the ISO100 elitechrome?
2) The 4000 dpi (with ICE and GEM function on) in fact creates a grainy,
streaky structure in contrary to my old 2500dpi HPs20 scans, for example in
blue sky areas of my slides. Is that the already the elitechrome film grain
scanned by the nikon? I scanned the slides in glasless frames. I heard the
elitechrome is not suited for scanning purposes, but other films are. Is
that right, what are they? I also found in scanned B/W negative ISO 50 films
grainy, but not streaky structures, but I guess that must be noise or any
other disturbance and not the B/W film grain?
3) I found out that 48 bit of color depth improves quality compared to 24
bit, but handling the resulting 114 MB tiff scans is not very practical
(zipping does not reduce size). Neither Nikon Scan nor photoshop (ver. 5
limited edition) can save these files as jpeg. Is jpg only a 24 bit file
color depth file standard? What to do?
