Scratched negatives: a quick solution for scanning

Recommended Posts

Advertisement (gone after registration)

Here I want to share my experience on scanning scratched negatives. I thought it might be helpful since recently there are many questions posted on this.

 

I've never owned an ICE capable scanner, so I had to find a solution for covering scratches on colour negatives when scanning them with my Konica Minolta film scanner. Post processing is not adequate in some cases. So 6 years back, I purchased a liquid solution called Rexton Scratch-Match from Adorama. It worked great! You just apply liberally over the frame you want to scan, it doesn't evaporate quickly and stays there. You wipe it off later, doesn't leave any residue. You can also clean the film with your favourite cleaner afterwards.

 

6 years fast forward, I am no longer living in the States, and similar products are not available for airmail postage due to harmful/toxic properties. So I had to find a local alternative.

 

TURPENTINE!

 

Yes, it is the same stuff, smells the same, and works the same, and cheaper! I read somewhere that Scratch-Match had some Chloroform (now a regulated substance) added to Turpentine. But apparently, Turpentine by itself works OK, too. I used distilled filtered Turpentine from Daler-Rowney. For better results apply with a flat painter's brush. Note that this solution doesn't help emulsion scratches.

 

Below is the proof. I deliberately scratched (a bit too much actually) a negative strip and tested for you.

 

Cheers,

Ever so thanks for the tip.

 

But, doesn't the dust get even worse on the wet surface? Though dust is easier to deal with than physical scratches or tram lines.

No, during scanning you try to work at a dust free environment. Any dust left on the negative is brushed away when you apply the turpentine. Some of the dust may get suspended in the liquid, but with consecutive brush strokes they go away.

 

By the way, this technique replaces nose oil, and can be applied in wet darkroom printing, too!

 

Cheers!

Does this work on the emulsion side too without causing damage?

 

Hi, Rexton Scratch Match was OK for the emulsion side (though, it doesn't recover lost emulsion), so pure turpentine should be fine, too. However, there is no point in using these on the emulsion side since any lost emulsion is lost forever, plus, fine scratches on the emulsion side does not appear on scans as far as I know.

 

Cheers,

I always assumed that the scratches I see in my scans were caused by me wiping the negative and scratching the emulsion side? I now do the final wash in distilled water and have eliminated them.

Scratch problem is most evident when scanning my C41 negatives, which are developed by local labs (and handled carelessly). My own home developed B&W negatives are mostly fine (except for a few odd dust speckles).

 

I assume that those C41 negatives arrive equally scratched on both sides. Applying turpentine only on the film base eliminates them altogether, so that's why I think the film base is the critical side for scratches.

PS: Similarly I use Brita filtered water for final wash, works great!

      Hey everyone, 
      I just got my m2 off ebay and had a look through the viewfinder only to see 2 main very noticeable spots. I attached a picture and the one on the lower left looks much dimmer and looks like a dot and a hair almost? It's kind of light greyish and I think it's a particle or dust but I'm not quite sure. However, in the middle the speck seems much darker (basically black) and more prominent. Could this be separation or is it another speckle of dust (imo it doesn't seem like one). If this has happened to you or you know what it is, any input on how to fix or your thoughts would would be greatly appreciated! 
      Also the shutter curtain on the front seems a little pushed forward and I can see the whole seam on it, is that normal? The curtain works 100% fine but I'm not sure if Im supposed to see the whole seam and overlap of the two curtains. On the back it stays slightly open by 1mm or so (didn't include a pic sorry)... should it cause a light leak? The camera was also recently CLA'd.
      Lastly, the viewfinder has some "gold specks" which I think is separation, but I hope i'm wrong.  
      Please help if you can clarify, recommend a fix, or give any thoughts on ^^. Overall the camera seems amazing and none of the things I mentioned has really bothered me, but if I can learn more about them then it would be great.
      Thanks in advance, 
      Ashley

      Hallo werte Leica-Forumsteilnehmer,
      vor gut einem Jahr hatte ich mich wegen eines Belichtungsproblems meiner R4 hier im Leica-Forum bereits zu Wort gemeldet (und weiss nun endlich auch, dass der kleine Elektromagnet, der die Springblende im rechten Moment stoppen soll, defekt ist. Alle bisherigen Reparaturangebote überstiegen aber bei weitem den Wert der Kamera, so dass ich mir als "vorläufigen" Ersatz für mein R-System eine zweite R5 zugelegt habe, die auch glücklicherweise tadellos funktioniert...).
      Ich möchte Heute aber ein anderes Thema ansprechen, welches mir schon seit einiger Zeit sprichwörtlich "unter den Fingernägeln brennt": Findet ihr auch, dass innerhalb von nur gut ein bis zwei Jahren das Preisniveau der Analogfotografie exorbitant gestiegen ist???
      Klar, dass das fast schon unterirdische Preisniveau für alte Kameras, Filme, Entwickler & Entwicklungslabore von vor gut zehn Jahren längst Geschichte ist, nie mehr wiederkehren wird und sicherlich auch dem Fortbestand der filmbasierten Fotografie nicht unbedingt förderlich war. Nischeninteressen können durchaus kostspielig sein, und dazu gehört klassisches Fotografieren auf Film ja inzwischen eindeutig. Aber was jetzt gerade abgeht - ganz ohne Corona-Krise - ist nun wirklich teils schon absurd! Da werden etwa für uralte, abgelaufene 135er-Diafilme wie Agfa Precisa oder Kodak Elitechrome teilweise reinste Wucherpreise verlangt. Hier mal ein Beispiel aus dem bekannten Online-Auktionskaufhaus:  https://www.ebay.de/itm/Fur-Sammler-1x-Agfa-Agfaphoto-Precisa-CT-100-36-Diafilm-Ablaufdatum-2014-12/223921237768?hash=item3422beef08:g:-OAAAOSwvRJeTrdi Aha, für Sammler also - ernsthaft?! Es gibt wirklich schon Leute, die jetzt unbedingt noch mal einen erst vor kurzem ausgelisteten Drogeriemarkt-Diafilm verknipsen wollen und bereit sind, derartige Wucherpreise zu berappen??? Bei den gebrauchten Kameras sieht es nicht besser aus. Auch hier meint wohl mittlerweile jeder windige, Opas Keller ausräumende Erbschaftler irgendeiner banalen Durchschnitts-Spiegelreflex, er habe das große Los gezogen und müsste hinsichtlich des aufgerufenen Verkaufspreises nun einen auf Fachhändler machen. Kam mir jedenfalls so vor, als ich unlängst eine Kamera für eine fotografierende Freundin aussuchen durfte, die nicht allzu teuer sein und einen PK-Anschluss haben sollte. Also mal bei Ebay-Kleinanzeigen nach alten Ricohs umgesehen, weil diese entsprechend eigener Erfahrung einfach, gut und robust sind. Doch dann kam tatsächlich nur sowas hier bei rum: https://www.ebay-kleinanzeigen.de/s-anzeige/ricoh-xr-10-mit-zubehoer/1332175555-245-4619 Die gleiche Kamera - ich würde sie als ganz gut ausgestattetes Einsteigergerät bezeichnen - habe ich noch mit einem deutlich besseren 50er-P-Rikenon vor drei Jahren für sage und schreibe 15 Euro bei einem Fachhändler (!) als Wühltischfund erworben. Sie funktioniert übrigens ganz ausgezeichnet, was ich von den genannten Privatangeboten eher nicht erwarten würde... Ich bin wohl nicht der Einzige, dem dieses aktuelle Wucherpreisniveau auf dem Gebrauchtmarkt aufgefallen ist, auch der von mir sehr geschätzte Foto-Youtuber Steffen Schüngel hat dies unlängst thematisiert: https://www.youtube.com/watch?v=YN1hXQmbaNA
      Was meint ihr, findet ihr auch, dass die derzeit stark steigende Preisspirale im Endeffekt zu einer weiteren Abnahme an Filmfotografie-Interessierten - inzwischen soll das "Jammertal" ja schon durchschritten sein und wieder mehr auf Film fotografiert werden - und damit irgendwann zu einem selbst für den geneigten Leica-Nutzer kaum noch bezahlbaren Vergnügen werden könnte? Die verschiedenen Meinungen hierzu würden mich mal interessieren.

      Life is pretty quiet photographically for me at the moment, mostly due to really bad weather with heavy rain which makes street photography almost impossible. This means I am continuing my journey through my archives, and this I had forgotten. It shows a typical English pastime - playing bowls. The white clothes are the standard dress for everyone, and afternoon tea is almost compulsory. English tradition at its best.

      Hello everyone!
      I'm new to the leica film cameras but I came up a rather very nice iiif in great condition which comes with a summarit 50mm f1.5 going for about $550. This sounded like a pretty good deal to me, however, upon closer inspection the lens seemed to have a lot of haze (not sure about fungus) as when I performed the light test there were specks everywhere. It seemed to be internal and in the second glass?? Not sure how to fix it or if I even can, also the focus ring was pretty stiff (but that isn't a deal breaker or anything). Like I said, the body of the camera was in very good condition however the lens is my biggest concern. As most of you are owners/experts and such please help me out and let me know if this is a good deal or not. 
      Thanks, Ashley

      Immer mehr Flughäfen rüsten ihre Sicherheitsschleusen auf neuartige CT-Scanner um, auch in Deutschland. Sie bringen für Flugpassagiere deutlich mehr Komfort, Filme und Fotopapier werden hingegen bereits bei einem Durchgang durch die Geräte ruiniert – davor warnen jetzt Kodak Alaris und Ilford unabhängig voneinander.
