filmscanners: Re: Nikon LS4000ED inquiry



Hello Bernard--

I've had my Nikon LS4000ED for about two months now the results have 
been mixed.

o Many of my negative strips come from the lab with a fine surface 
scratch running down the non-emulsion side of the negative.  I have 
an older filmscanner that entirely ignores these.  Same with my new 
flatbed scanner (ScanMaker 8700).  But the Nikon not only "sees" 
these scratches, it turns them into glaring white scars across the 
length of the image.  ICE does an incredible job of removing most or 
all signs of these scars, but they shouldn't be there in the first 
place.

o The Nikon strongly emphasizes the grain in Kodak Gold 200 negatives 
to the point where even a small amount of unsharp masking overwhelms 
the image with graininess.  GEM often, but not always, does an 
excellent job of softening the grain to that the scans can be nicely 
sharpened but increases processing time.

o You have to decide whether or not to use ICE and/or GEM BEFORE you 
scan.  You can't do a bunch of scans, examine them, then run ICE 
and/or GEM on only the few scans you feel really need them.  The 
result is that you either have to commit ALL your scans to ICE and/or 
GEM (at a huge increase of processing time!) or (potentially) scan 
each image twice: once to see if you need ICE/GEM, and again to  use 
them.  Also, each time you decide to set the ICE/GEM levels higher or 
lower and compare the results you have to do a completely new scan.

o So far I haven't had a problem with scratches becoming scars when 
scanning Kodachrome of Fujichrome slides.

o Scans of Tri-X negatives extremely grainy (but then this is a grainy film).

o If you use out of the box color management settings you will get 
very nice color and tone from Kodachrome slides.  However you don't 
get the maximum dynamic range or shadow detail that the scanner is 
capable of.  So if you want to pull the most detail out of deep 
shadows, and/or if you want excellent color and tone, you have to 
turn color management off, do a "raw" scan (although these "raw" 
scans have good color and tone, so obviously the data is NOT coming 
straight off the CCD array), then apply a custom profile which you 
previously made using an IT8 target and third-party profiling 
software (I've been using IT8 Scan from profilecity.com).

o The stories you've read about poor depth of focus are true!!!  I've 
got some 20 year old Kodachromes that are perfectly clean and well 
maintained but curved (which is normal for this film).  The depth of 
focus is so poor that the out of focus parts of the image (when 
scanned at 4000 dpi) are blurrier than when scanned with my old 2400 
dpi scanner.  For some slides this is still true even if I set the 
focus point of the scanner to be halfway between the curvature 
extremes.  One user has reported vast improvements by remounting all 
his slides in Quickpoint mounts, and others have discussed using 
glass mounts, but I have thousands of slides that I definitely DON'T 
want to remount.

o In general I like the NikonScan 3.1 software on my Macintosh very 
much, although the UI is very slow to respond whenever it has to draw 
or update an image on the screen.  In standalone mode it also is 
extremely slow at saving files, loading files, refreshing image 
windows when change which one is on top.

o The basic slide adapter is very nice, you just pop a slide into the 
slot, and when you're done push a button and pop it out.

o The filmstrip holder is not so nice.  It had four independently 
moving parts, some plastic and some metal.  Getting the filmstrip 
inserted and the holder closed with all the moving parts aligned with 
each other is a real pain, and it's impossible to do without getting 
fingerprints somewhere on the film.  Once the film is mounted you 
have to slide the inner (plastic) frame back and forth within the 
outer (metal) frame until the negative you want clicks into view in a 
cutout in the metal frame, then you pop the holder into the same slot 
on the scanner used for slides.  This works pretty well once you've 
gotten the film into the holder.

o It also comes with a motorized filmstrip adapter.  The is a cool 
idea in that you just feed the end of a filmstrip (of 2 to 6 frames) 
into the slot and it grabs it and pulls it into the scanner.  In 
practice however it is cranky, inconvenient, and frustrating.  (I'm 
tired of writing so I won't go into detail.)

o This is NOT a production scanner.  It takes so many trials to 
decide how best to scan each individual image, and it takes so long 
to actually perform each pass, that you couldn't possibly do 
high-volume work.  Think of each scan as being a hand crafted job and 
you'll be in the right frame of mind.

o You need tons of RAM if you want decent speed.  First you need RAM 
just for doing the scan (120MB per full frame, 4,000 dpi, 48bits 
max), then you need lots of RAM for the post-processing.  After 
getting the raw data NikonScan uses your computer's RAM and CPU to do 
the post-processing required by color management, ICE, GEM and/or 
ROC.  I did one 120MB scan with ICE and GEM that took SEVEN HOURS to 
complete.  This was because I didn't have enough RAM and it was 
accessing the hard disk continuously for those seven hours.  Once I 
got enough RAM the time went down to 20 minutes (?) or less.  Also 
note that Photoshop itself needs working RAM that is 3 times the size 
of the image you're working on.

Well, that should be enough for now. Good luck,

--Bill
