Sprintscan 120 glass film holder - 

what are you doing to limit dust ?
I have cleaned thoroughly with lens cleaner and lintless tissue.
I've used dust off (compressed air).
I've used the 'yellow' Ilford anti static cloth.
And still the dust is a Huge provblem.

Using the Silverfast srd dust & scratches is ok but by the time the 
software is set to eliminate this amount of dust, it's degrading the 
image significantly.

thanks,
Frank

The Ilford cloth, believe it or not, is kind of an oily base.  So, while it
helps with film, it is not suitable for lenses.  I would not use it on the
glass either.

Blowing air can create static also. Blowing off a neg and immediately
inserting it in an enlarger takes less time than then sandwiching a neg.

Try a neutral glass cleaner. A major camera company advised me to use Windex
--NO additives (lemon, ammonia, vinegar)-- diluted 1:3 with distilled water.
Safe for lens coatings, should be fine for the glass.

But, my guess is it's your invironment.  Dry? Negative air pressure?  Try a
closed door with either a humidifier or air filter or both, but not
immediately close.  A filter can take hours or a day to reduce dust.
Vacuuming kicks up dust.  

The humidity keeps dust from flying.  The anti-static agent we used in
computer areas years ago was liquid fabric softener diluted 1:8 or so,
sprayed on the carpet with a spray bottle.

Just some thoughts.

Thank you - I was using the anti-static cloth so I'm going to switch to 
the windex method, I guess. Last night I got a newton ring on a shot - 
must've been from the oil in the cloth???

Tigercloth from Light Impressions. I use this for cleaning glass while
framing prints. It uses conductive stripes in it to dispel static. It
sort of works, but yes if I then use compressed air, it negates the
improvement somewhat. I also use Tiger cloth to pick up specks on both
inkjet and my old Silver Gelatins that can't or shouldn't be blown
away with the air compressor. It doesn't seem to scratch if you drape
it onto print, not rub.

Polygenix also makes gloves that are static disipative, 2 for $25 if
you get it from their site, or Light Impressions has it for more (look
for the picture of the "striped looking gloves" item 7115). I like
these much better than straight cotton gloves. I handle Photorag with
these gloves.

I agree about raising humidity helping control dust. It is
unbelievable here, we are semi-arid complete with blowing dust
occasionally whipping winds of 70-100 mph around the studio corner,
and humidity dipping to 20%RH. I use a sealed door and windows and a
HEPA air cleaner rated at greater capacity than room needs, but still
have some problems.

Nice scenery though...<GG>

Why do you need the glass carrier? I have one for my SS120 but only find it 
essential when I absolutely must scan all the way to the edge of an image. 
Lots more dust to spot when I do. Most of the time I use a 120 holder that 
I've filed out to the maximum opening that will still hold film. This gets 
me close enough to the edge of an image so that the glass holder is rarely 
necessary. I've found that the SS120 has enough depth of field to assure 
sharp focus in large blowups without requiring the agony of four additional 
dust-catching glass surfaces.

Victor,
I do sometimes use the glassless too - but I find that I get sag and 
the focus is not as good as with glass. However if the neg is the 1st 
one on the strip and can be supported on 3 sides of the glassless 
carrier then it's ok
Frank

I'm not Frank, but just thought I'd throw in my two cents. I'm using 
the glass carrier because I'm scanning Hassleblad Xpan negs (panoramic) 
and they definitely don't stay flat in the regular carrier.

Just a warning for those of you with glass holders for the SS120 - last 
night the top window came out and in trying to (gently) put it back in, 
I tweaked it a bit too much and it cracked the glass on the underneath 
part. The crack is way to the left and my negs don't reach that far (at 
least the ones I'm scanning at the moment), but I thought it would be 
good to get out the word that this can happen very easily.

I guess I should order a new one as a backup at this point.
