Post Processing Noise Reduction

[Trail Images]

Any positive input on noise reduction programs that actually work? I have used PS5 and NIK for years with mediocre success. Usually not an issue with exposures, but I have one or two direct into the sun starburst scenes where the dark areas are really trashed with noise. I have a revisit to the site on Tuesday for some retakes, but still curious of any users with real solutions. Thank you in advance for a product or ideas that work.

This is posted in Hybrid, so does this mean you're dealing with noise in scans? Or are we talking about digital captures?

Scanned images. I've used both PS5 and NIK noise reductions with little success. Looking for those that have used other standalone or PS plugin software that are up to date and powerful.

I found the scanner has very little noise as it has sufficient light for the exposure. If the OP said noise means grain then usually the scanner software does a better job.

The noise is from usually underexposed area in the image. It is an item to be treated in post processing with various noise reduction software such as Topaz & DXO and others. Just looking for someone who has used a program they can recommend that works better than just basic inclusion programs.

If you scan from a negative then the underexposure part would have less noise from the scanner but more grain from the film.

A long time friend on another site who is a film scanner uses "Neat Image" and loves it. Anyone using that by chance with scanned film?

I don't use it often but I do use the Grain Dissolver feature of the Minolta Dimag Dual Scan software. It works OK.

The problem is that it‘s nearly impossible to eliminate scanner noise without affecting the grain texture.
If reducing/removing both is desired, NeatImage and Topaz AI both can do an amazing job.

Personally I really like the texture that film grain provides to an image, but dislike noise or other scanning artifacts, so in this case a clean scan is really the only option.

Can you post an example picture?

This image is scaled down quite a bit. But you might see the noise in the FG grass area as it was very dark in the exposure and required lifting the shadow a lot. Typically I photograph in non contrast light and use ND's or Reverse ND's when needed knowing the film latitude. But this was an image from years ago that I cannot take over again.

That's a really remarkable noise pattern. How did you digitize this film?

 

[brbo]

Yeah, that's some heavy noise.

As you say, you can't retake that image, but you can rescan it on a better scanner. Maybe that would be a better option than trying to get rid of sensor noise?

Just to be clear, you are seeing this noise when viewing the negative with a loupe on a light table, right?

Or to ask the question another way, is your scanner faithfully capturing noise/grain as it appears on the negative -- or is your scanning process introducing noise?

What I can see in the grassy area of your posted example looks like noise introduced by the scanning process. If so, I would be looking for ways to prevent the noise up front rather than trying to eliminate it later.

EDIT: It may take a little bit of both prevention and reduction to get where you want to be?

I'll see about doing a re-scan at some point. Having life events crop up recently that will delay things. Thank you each for your thoughts overall. Much appreciated.

Agreed. I'll need to take another look see.....thank you.

Looks like the image has banding problem.
