Default Dealing with grain - 05-01-2007 , 10:09 PM






I'm starting to scan a roll of film I took about 4 years ago - using Vuescan
on a PC, and scanning with the Minolta Dimage Scan Elite 5400. My result
looks like way too much grain, whether using Vuescan's grain reduction or
Minolta's - the clumps appear to be slightly larger using the Minolta.

A crop from the scan, at 100% and no adjustments whatsoever, is at

Any solutions? suggestions? to deal with this?

What film? How was the scanner set for sharpening? How dense are the
negs? Over exposure in negative film (looked like neg film from the
example) will build your grain, sharpening during scanning will do the
same. If the film had an ISO over 200 there will be a lot of grain,
there are some new ISO 400 films that are better but nothing like ISO
400 digital. Also some film scanners at lower resolutions will clump
grain. Try turning off scanner sharpening, process the image, then
sharpen in Photoshop or other editor.

Kodak Advantix 200 film - scanner set for no sharpening. Scanned at the
full 5400dpi.

Have tried scanning at a lower PPI ?

Looks a bit like ccd noise to me, but it is hard for me to be sure. Do
you have a dark frame to scan from this roll ? Noise Ninja might help.
or multisampling, possibly multiscanning and overlaying.

You can look at it another way using neg film you diffuse the image
through an enlarger to blend/soften the grain, Where as a tranny is
diffused within.

So you will get more grain with a neg. The final scan you can do some
work in say Photoshop.

I have found sometimes its worth scanning the print for a better result.

200 Advantix, eh?

I'd blame the film.

What size are you hoping to print?

Bring it into Photoshop from Vuescan or the Minolta s/w. Ignore the
grain. Work the image to "what you want" and give it a gentle USM to
sharpen it up before printing.

The grain looks fine. If you wanted less grain you'd need to expose
the negative more- too late for that. Using 35mm over APS would also
help. If anything it looks a bit soft- was it in focus?

I'd suggest running noise ninja on the image if you plan to print it
large and the results should be fine.

Thanks to all. Perhaps I'm just 'hyper' - glad you say the grain looks
fine. I did print out another image from the roll, and the grain was barely
visible. I use NEAT Image myself - started with that and have stuck with
it, but had not applied it to the image posted. Scanned some more today,
using DimageScan - colors a little different, but apparent grain about the
same. Applied NEAT filter in PS - it did help.

The image was in focus - I adjusted contract (Levels), reduced the size and
then sharpened for this result:

Did you remove the photos? Photo.net says it's a bad link.

Sorry - I did: I thought the thread to be ended.

They're reposted now at

http://www.photo.net/photodb/folder?folder_id=673019

The one on the left is color-corrected, reduced in size and sharpened for
the web.

The one on the right is as scanned using Vuescan, the Minolta Dimage Scan
Elite 5400 (original model), with no color or tone correction and no
sharpening. A crop from the full scan, of course.
