Hi All,

Ever try scanning a colour neg? If you are like me and my canon film scanner, the results can be downright ugly. Grain, grain and more grain with mediocre colour and contrast. I understand there may be some scanners out there that do a decent job but I have not run into any yet.... until this week.

You see, a while back I had some C-41 negs in for processing at a local lab that had recently aquired a fancy new Konica mini-lab. The machine makes pretty decent prints from 35 and medium format negs and transparencies. It does so by first scanning the neg and then printing on RA4 type paper.

The day after dropping the negs off to be processed and printed, I got a call from the lab telling me that there was a problem with one frame on one of the rolls. It seems that a small piece of the emulsion had flaked off during processing. The lab manager, a great guy, said the problem could have been a bum roll or it could have been their neg dev. machine at fault. In any case he proposed that they set the scanner on the printing machine to the highest resolution it was able to muster and save the scan on a disk for me. That way I would at least have a file to use in case the frame was a "money shot" that absolutely needed to be fixed in photoshop and then printed.

Well, after all was said and done, I got all my prints and a disk with the scan of the damaged neg frame. It was not a "must have" shot anyway so I was relieved but somewhat curious as to how the scan would look. Well lo and behold, when I openned the file I found the best scan of a colour neg I have ever seen. The file was HUGE, the image clean as a whistle and spot on for colour, contrast etc.

Now, you may be wondering what I am yammering on about but if you have ever tried to scan a colour neg or get a decent scan of one done, you may have realized that it ain't easy. For some reason, most dedicated film scanners seem to really accentuate the grain of colour negs...especially 35 mm. In the past I would actually make a print and scan that instead of scanning the neg.

Let's face it from time to time, many of us need a good scan of a colour negative. Whether it be to post a photo to a website or send it as an email or even to rescue in Photoshop.

So considering the outstanding quality of the scan I got from the lab and the equally good quality scans I have gotten from a few more that I had done, I would just like to suggest that if you ever find yourself requiring a good scan of a neg, check wtih the local labs in your area. If they are running one of the new machines from Konica or Fuji or even Kodak, they may be able to make you a great scan at a fraction of the cost of the pro lab using a drum scanner (our local lab with drum scanner actually has the same problem with pronounced grain. Apparently they will not scan colour negs, period). See if the local lab can crank up the resolution on the scanner and save the file to a disk for you. The ones I've had done, colour negs and transparencies in 35 and MF have been gorgeous....and less than a quarter of the price of a drum scan.

Try it, you might like it.

Cheers!

scanning color negs/slides

I have had similar issues with scanning color negatives and even worse issues with slides. I am not sure exactly why, because black and white scans from my Epson 3170 come out very very nice, but the color negatives or slides are invariably cruddy. Yeah, the colors are muddled, the contrast is terrible, the dynamic range is shot up bad, and the grain has been made painfully obvious. I know that my old dedicated film scanner, Minolta Dual Scan II or IV doesn't do this as often.

Luckily, I am almost entirely devoted to B&W, so this is rarely a problem, but it does seem to be a major roadblock in the workflows of photographers who don't own $12000 drum scanners.

DMAX ratings and resolution are probably major factors in the quality of your scans, you might want to take a look at the newest of the Epson flatbed film scanners with 4.2 DMAX like a drum scanner. My friend uses one and it does a spectacular job on his 6x9 color negatives (portra 400 NC).
 
Yesterday I collected my first set of scanned colour negatives from the shop. They offered standard- and hi-res options, so I went for the high-res. I was also surprised and impressed. On disc the files are about 3mb each in .jpg format. Can't remember the actual resolution or dpi. This was from my first test roll with the Olympus-SC.

Here's a picture I just picked up from the local drug store (Chemists) last night. I scanned thge negative at 4800 dpi on my Epson 4180, reduced the dpi's to 100 and resized to 8.5 x 5.5. While I'm sure it's not the best that can possibly be done with a better scanner, I'm happy with it.

Those are some fine looking scans!

As I mentioned in the original post, I am sure there are now some great scanners out there that can do an excellent job with colour negs. In fact the Canon flatbed that I have scans medium format negs very nicely. It will not do 35mm though.

To my mind, scanning is an art in itself, and one that I am not too keen on. I do it grudgingly most of the time and then, only at lower resolutions for screen use etc. I find it tedious and frankly, I am not very good at it. Every so often I am tempted to buy a new scanner but if I wait a day or so the urge invariably wears off (much like my occasional lust for a newer top of the line inkjet printer. I get all hot and bothered for the latest greatest spewer of ink.....and then realize that working with the things doesn't really float my boat like a wet darkroom session does. My Canon s9000 inkjet printer rarely sees action nowadays).

The scans I had made on the lab's print machine were for portfolio pieces and a book project I am working on. I do not think I could have achieved the quality with my gear even if I had the patience to try. Each file was nearly 100 MB's (surprisingly the 35mm scan was larger at 104 MB's than the MF neg and tranny at 95 MB's each). I was charged about $12 CD for each scan. Not dirt cheap but a far cry from the $50 or more each would have cost from a drum scanner.

Now I can practically hear the calculators buzzing out there as someone figures out that at 12 bucks a pop I could pay for a great scanner after only X number of scans. To that I reply: see above re: tedious and not too good at it.

One other thing I should mention is that there are a couple of labs here in town that charge a whopping 3 bucks to develop a roll of film and scan the whole thing to a disk (no prints) at a resolution good enough for rock and roll. I have now taken to using my old Leica and Contaflex almost like I would my digital cameras. I simply load them up with XP2 and shoot to my heart's content. The film is then developed, the images burned to disc and this in under and hour, for three bucks!

The scans are great for emailing, posting to a website and best of all for proofing to see which ones I want to take into my darkroom to print.

All of the photos I have in my (meager and neglected) gallery are straight from scan CD's processed by the 3 buck a roll lab next to the liquor store that keeps by single malt collection alive.


Skol!
 
I haven't had good luck scanning 35mm color negs on my Epson 2580 either. Any tips or tricks for doing so would be much appreciated. I've tried Vuescan but it locks up the scanner every time I try to use it even though I have a compatible model. Strange but a minor issue since I've figured out some ways to get decent scans using the Epson software.
 
Dug out the details when I got home: according to the file properties the image is 3000 x 2000 pixels, 400 dpi and 24 bit depth (wassat?). Here's a small section of the image I linked above, at full res.
 
My (now) oldish Minolta SD3 gives perfectly good scans, even with minor tweaks to the standard settings of the standard scanning software. My photos that got published in the rangefinderforum book were scanned with the SD3.

Grain can sometimes be a problem but I shoot iso400 film so I kinda expect at least some grain. Blown highlights can also be a problem but that has to do with the limited range of the scanner (same as with the sensors of digital cameras), and much can be prevented beforehand while shooting (though I usually overexpose my shots slightly to get more shadow detail).

I used to have a HP S20 negative scanner, which performed like a charm. I was quite sad when it finally gave up the ghost.
 
Dear Craig,

I recently scanned some Kodak Portra and Agfa Vista negs with my Konica Minolta Dimage 5400 II (I think that's the full title...) and was much surprised at how good they are. Apparently this scanner borrows some technology from their minilabs, which ties in well with your observations.

I fully take your point about not scanning unless you have to, but equally, I live 25 miles from the nearest good minillab and I need a lot of pictures because of what I do for a living. Owning the right scanner therefore makes sense for me -- but I don't own it because I WANT it, I own it because I NEED it. There are many things I'd rather spend the time and the money on.

This well illustrates the dangers of universal advice. What's best for me isn't necessarily best for you, and vice versa.

Cheers,

A dev and scan to CD in local minilab was €3. Last year.

This year the price jumped to €6.

Nice quality scanning, but on and off cropping at random, and they are not much help when I ask them to redo it and capture the full negative area and not just the bit they fancy scanning today.
 
Wow, the price for develope and CD (no prints) for me is $3.49 CAD taxes included. I sure hope they don't take a huge price jump like you face.

That's _good_ Bob. Which chain is it? or is it a local store?
 
For all you inquiring minds wanting to know it is a Shoppers Drug Mart location.

Thanks... I have one across the street. Actually I have 3 photolabs in the mall across the street.
