stump4545 Posted September 20, 2011 Share #1 Posted September 20, 2011 Advertisement (gone after registration) just got my entire b+w negatives scanned and archived but they are loaded with scratches and dust. does anyone know of any software or plug in that can reduce many of these scratches rather then do it manually by hand? thanks for the help Link to post Share on other sites More sharing options...
Advertisement Posted September 20, 2011 Posted September 20, 2011 Hi stump4545, Take a look here scratch removal for 35mm b+w scans. I'm sure you'll find what you were looking for!
alun Posted September 20, 2011 Share #2 Posted September 20, 2011 I've always understood that digital ICE and variants don't work on conventional BW film but perhaps others here know differently. Link to post Share on other sites More sharing options...
Tor1Amos Posted September 20, 2011 Share #3 Posted September 20, 2011 Scratches cant be removed in B&W negatives (if you are planning to scan them) Dust spots and other eh.. thing can be removed in software - but not scratches along the hole negative. The choise of scanner might be important. On my Canon Canoscan US4000US I get far better results than using my (now sold) Nikon coolscan 5000ED. The Coolscan is a bit sharper, but also shows much more scratches. Digital ICE and such does not work in B&W. Link to post Share on other sites More sharing options...
andybarton Posted September 20, 2011 Share #4 Posted September 20, 2011 You can try using NeatImage or something similar in Photoshop, but it's obviously much better to start out with a clean negative. ICE does not work with silver based b&w film Link to post Share on other sites More sharing options...
russell Posted September 20, 2011 Share #5 Posted September 20, 2011 Theory has it that the Minolta 5400 and the Nikon 9000 has more diffuse light which helps with scratch and dust. I've used both and that's somewhat true. It helps but I'm not sure it's all that big of a difference. I've tried wet mount but the extra time and hassle wasn't worth it.

stump4545 Posted September 20, 2011 Author Share #6 Posted September 20, 2011 is there a plug in for aperture3 that removes most dust? what is the best method to remove scratches in aperture3? wow i never knew how many scratches my b+w negatives had until i scanned them. thanks for the post processing help.

pico Posted September 21, 2011 Share #9 Posted September 21, 2011 just got my entire b+w negatives scanned and archived but they are loaded with scratches and dust. What does 'entire' mean? A roll, ten rolls, hundreds of rolls? In any event, if it is just a roll or two you can have them cleaned and wet scannned to minimize scratches. Or clean them the best you can of dust before-hand.

adan Posted September 21, 2011 Share #10 Posted September 21, 2011 As to a plug-in for correcting dust/scratches after the fact: - the problem is that it takes human intelligence to tell whether a given white spot is dust or a scratch - or a tiny white highlight or detail that is SUPPOSED to be a white speck or line (or film grain). The Universe is not big enough (nor Time long enough) for code that could accurately and consistently determine which is which. Frankly, there are times when I can't tell for sure if a given white speck is dust - or a speck of mica reflecting a pinpoint of light from a road, or a distant sequin on a dress. (The same was sometimes true for manually spotting chemical prints, for that matter.) PhotoShop has a "dust and scratches" filter that works OK in areas of smooth tone - most of the time - if one knows how to supervise its decisions, and use the "Undo" command liberally. Depending on the picture, it can sometimes handle 20 or 50 or 80% of the artifacts on an image. Really getting control of it has a learning curve of a couple of years. For the record - Digital ICE works by scanning the film using infrared light. Color film dyes (or the dyes in chromogenic B&W films like Ilford XP2) are mostly transparent to infrared, so the IR scan shows a mostly blank image - except for dust or light-refracting scratches. Thus the software can subtract the IR-revealed dust specks from the RGB scan. Silver metal film grains are NOT transparent to IR light, so the ICE software sees every silver particle as a dust spot, with psychotic results. it deletes large part so fthe imahe (especially in dense highlights). Kodachrome dyes are not as transparent to IR as are E6 and C-41 dyes - so Kodachrome also has problems with Digital ICE. I scanned a (very dusty ancient) Kodachrome slide of a silhouetted fisherman for a colleague, and the ICE "ate" the black fishing line - it vanished entirely. I ended up having to paste a straight scan of the fishing line into an "ICE'd" version of the other 95% of the image. Link to post Share on other sites More sharing options...

stump4545 Posted September 21, 2011 Author Share #13 Posted September 21, 2011 i know the spot tool in aperture can take care of the dust but any suggestions as to what tool to use to get rid of scratches in aperture 3? Link to post Share on other sites More sharing options...
tgray Posted September 21, 2011 Share #14 Posted September 21, 2011 The healing brush in Photoshop is pretty good, but you got to do it yourself. If you saved the IR channel from the scanner (as an RGBA channel), you can cook up a photoshop action that processes that and uses the result as a mask for the Dust and Scratches filter in Photoshop. While I've never tried that with traditional B&W film, I use it all the time with Kodachrome and it works. I'll have to look and see exactly how bad the IR channel on a B&W scan looks. You might be able to tweak the thresholds to separate the scratches/dust from the silver... But I'm guessing you don't have IR channel data. So, try the healing brush. Or maybe Dust and Scratches, but that will invariably soften your photo. At the very least, create a mask from the highlights in the images for use in dust repair (scratches and dust should always be white, right?).

I tried it years and found that it softened the image to an unacceptable degree. Take a look at the before and after shots in this link... Free Dust and Scratch Removal software saves your scans | Alphatracks There's also a link to the software itself at the bottom of the page - I have a feeling that it won't work with the later 64 bit versions of Photoshop.

tgray Posted September 21, 2011 Share #17 Posted September 21, 2011 thanks for the advice but i am using aperture3. any tips for aperture 3? thanks a lot. Nope. Personally I don't find Lightroom, Aperture, and other programs aimed at digital cameras all that useful working with scans, for the reason you are running into - they don't provide the tools you need. Sure, they are great if you have a scan that has already been dust busted and color corrected to neutral... Link to post Share on other sites More sharing options...

No idea about Aperture as I don't use it, but I'd be surprised if you couldn't. Link to post Share on other sites More sharing options...

No idea about Aperture as I don't use it, but I'd be surprised if you couldn't. You can't color correct all the things that you sometimes need to, unless they've finally put in a full curves adjustment. As far as dust - yes, but scratches I would think are more difficult. Aren't the dust removal tools all based on single circles? Link to post Share on other sites More sharing options...
