B&W processing, HP Photosmart negative problems
Alex Wetmore
my HP Photosmart Scanner (I don't have an enlarger at this time). I'm
running into problems with the scanning.
The scanner doesn't seem to be able to grab onto the negatives well enough
to pull them in. I think that this could be from two things:
1) The negatives are a little thinner compared to the color negatives that I
tried (probably Kodak Gold 200, although I didn't check).
2) When I was processing the negatives I used Kodak Photoflow at the end.
This is a soapy water mixture used to eliminate water spots on the negatives
when they dry. I'm wondering if this made the surface too slick or
lubricated for the scanner to be able to pull them through.
Does anyone have any ideas about the latter theory? Would washing my
negatives again (to get rid of the photoflow) and redrying them fix this
problem? Has anyone seen anything similar?
thanks,
alex

I have not experienced this problem while using the Photosmart to scan Tmax
and Kodak HIE, which is much thinner and curlier than Tmax. I also use
Photoflo at the end. Are your negatives very slippery to the touch? If so,
perhaps you are using to strong Photoflo concentration. Other than that, I
would suggest checking out your scanner.

Normunds

I use Photoflo on Tech Pan and HIE, and they're both considerably
thinner than TMAX or other standard B&W negatives, but they both
scan well on my Photosmart, so I don't think thin film or
Photoflo are the problem.
What strength do you mix your Photoflo at?
One thing that will interfere with the Photosmart is excessive
curl -- if your negatives are trying hard to roll themselves back
into a spiral, they won't feed properly. I sometimes run into
that with HIE.

They aren't trying to do curl...they lay pretty flat. They were bowed at
first, but I left them sitting in an archival sheet under a ream of paper last
night. Now they sit as flat as any of the other negatives that I have. The
negatives dryed with a clothespin weighing them down (to avoid having them
curl).
I mixed the Photoflo to Kodak's directions. They recommended mixing 34oz of
water with Photoflo going to the top of the threads in the bottle's cap. I
did half of that (17oz, and going 1/2 way up the threads).
I'll experiment with cleaning the rollers in the scanner tonight. Almost all
of my usage of the scanner has been for scanning slides, so I've done very
little in the way of scanning negatives. The last time that I tried to scan
negatives was almost a year ago (when I first purchased the scanner) and I had
no problems at that time.

scanning' mode, aren't you? If you left it in the same mode you use for
scanning your slides the slot would be wide enough to accept your negs,
but the scanner would be 'looking for' something thicker, and would not
grip the neg strip properly.

The Kodak recommended dilution is a higher concentration than
a lot of people like to use (I use about half that myself),
but it certainly should not leave any detectable surface
effects on the negatives (other than perhaps a slightly
higher risk of leaving visible deposits on the film.)

what you think of the results this scanner can produce? Are you happy with
it? After owning it for a while, would you prefer a better one?
Thanks muchly,
Cheers, Rene

thin. I had some trouble at first, you just have to apply a little
pressure to the two sides of the film to keep it straight going into the
scanner.
