I've recently scanned several hundred slides and negs. And have thousands to go! LOL!

I am getting a LOT of grain/noise. Really bad.

I'm using Nikon Coolscan 4000 with NikonScan s/w v4.

Settings are RGB, 4000 ppi, save as .tif, single scan. Digital ICE turned on.

What sharpening settings do you recommend?

Does use of curves increase likelihood of noise even if I carefully watch the histogram to avoid cutting off blacks and whites?

Thanks!

Here are my personal notes for the settings I used when scanning. Most of my scans were of Kodachrome, and some was colour negatives. I had no problems with grain, except for some really poor high speed slide film - but the originals were grainy.

You will need to tweak what I've written. For example nowadays I would have scanned to TIF not JPG. I did all sharpening and adjustments afterwards, and did as little as possible in the scanner. I would not attempt sharpening in the scanner, post processing programs are likely to be better.

Here we go...

Film Scanner
Nikon LS5000ED
SA21 film scanner
SF210 loader for 50 slides

Nikon Scan 4 - Setup

Preferences
Color Management: sRGB
Single Scan: Save to disk
Batch Scan: Don't create scan log
File Saving: JPEG, High Quality
Automatic Actions:
- Preview when film inserted - turn on or off for single slides, otherwise always turn off.
- Turn on Thumbnails when film inserted.
Preview Settings: All on except Multi sampling.

Scan settings (Tool Palette)
Crop: Keep this crop, Scale set to maximum, Resolution 360 pixels/inch
Digital ICE4: Enable Digital ICE
Enable Post Processing ROC 5, GEM 3
Analog Gain: Master 0.5, rest 0.0
Scan Image Enhancer: Enable
Scanner Extras: Set Slide Feeder Scan Feed Images to number of slides or more

Each scan
Input type: Positive, Negative, Kodachrome
Slide Feeder: Number of slides or more, up to 50
File saving: Starting Index

Notes

Attach the scanner, then switch it on, then run the Nikon Scan program.

When scanning negatives using the SA21 film scanner, wait until the status light stops flashing before inserting the film. Otherwise the program may not realise that a film has been inserted, so that it has to be closed and restarted.

When changing Input type, it may be necessary to set this, save settings, and shut down and restart the program for this to stick.

Thank you so much! I was hoping you'd see this thread!

I was using curves and had read recommendations to set sharpening to 20/10/3. I'll discontinue using both.

I forgot to mention that I'm scanning @ 14 bit....

I haven't tried ROC and GEM.....I'll also give that a try.
