I just bought a Canon FS4000 and am really not happy. The images are really contrasty and way way too much grain. Is there a program that removes the grain. Also when I scan a Kodachrome slide, it is very contrasty. How do I reduce the contrast without making the image look muddy?

I use the FS4000, here are a few tips re grain.

1 Turn the 'Sharpen' function off
.

2 Dont scan at too high a resolution, 2000 is fine for most images. I only use 4000 if I'm enlargeing a small part of the image.

3 In Photoshop, use Filter> Noise> Despeckle on the Blue layer (in the Channels Pallette). You can apply this 2 or 3 times without affecting the quality of the image.

4 To correct contrast, use the Curves option in Filmget - move the bottom left hand point up to lighten the blacks, and the top right-hand point down to improve detail in the whites. You can also do this in Photoshop, but you must get the highlight detail right in Filmget first.

Thanks so much Brian for the information.

Neat Image release 2.0, Home or Professional release does a good job of handling grain (or noise as some refer to it) especially when properly applied.

Although I scan a lot of photos of many different sizes, as well as negatives and some slides; I am not familiar with your specific scanner. If you have scanning software to adjust for proper exposure and contrast (before scanning) this should improve results. This has been my experience.

I bought a CanoScan FS4000 US recently.
(Did only do very limited scanning)
I was appalled by the grain, but Neatimage 2.0 trial version
did an excellent job removing it "completely".

Issues I still got scanning negatives 4000dpi:
  • Neatimage trial version is 24 bits and not 48 bit, guess I have to buy it.
  • Best cleaning agent/cloth yet to be decided upon (should be relevant
only to scanning my kodachromes, as IR dust "removal" of FS4000 US looks good)
  • Using Vuescan under Linux does not work for me (I use USB). I have to use the windows
version of vuescan.
  • Lossless compression is not good with the grainy scans (I would like the save the raw scans)
  • The best lossless compression software ERI 5.1fre only works with 24 bit images and is,
as said before, worse than ordinary png.
  • Scansize is humongous (130Mb uncompressed with 4000dpi), guess I have to compromise.
 
I have this scanner. Just where do you turn the sharpen off? Where is the control at?

I don't have that model, but USUALLY it is in the software. Look for a check box when selecting DPI, contrast, etc.
 
Thanks Pete but you cannot turn the sharpening off with the provided software. If I get the 3rd party software called Vuescan then I can have it on or off. But it has not been a problem. I have made 16x20 prints with the scanner with no grain problems. Maybe I suspect it's because I always used the finest grain film available such as Kodachrome25.

Hi Davidlw,

I have the FS4000US and I know exactly what you are going through. Here is a link to a site that has excellent information on the FS4000US ( http://www.normankoren.com/Tutorials/Canoscan4000.html ). It contains a wealth of info on techniques, etc. for using the scanner as well as how to handle the grain issue.

Another site to check out is http://www.michaelalmond.com/Articles/noise.htm . This site tests 12 different plugins, actions, etc. for grain / noise reduction. Prior to finding this site, I performed my own tests with the majority of software (and actions) listed. My findings pretty much paralleled those listed on the site. I finally purchased Neat Image Pro ($60) because it did a better job than any of the others (even those at 2 or 3 times the price).

One other plugin that is worthy of mentioning is iCorrect EditLab 3.0 by Pictographics. It does an excellent job of color correction and is very quick and easy to use. I have quite a bit of experience with this scanner and I have grown to love it. If you would like any other info just e-mail me and I will try to help.
 
Thank you Greg for the great link about noise reduction! I never get to bed because of finding good stuff like this. I too love that scanner and as I said earlier my grain problems have been minimal FOR THE MOST PART but I do have the grain on some of the B/W like Tri-X. Are you using the Canon software or something like Vuescan? If you have any thoughts on Vuescan I would appreciate them. John

Yes I agree, Neat Image does a great job with grainy scanned film, much better than I have been able to do with Photoshop. Also the film type is very important, of the films I have tried, Fuji Velvia 50 and Fuji Provia F 100 are by far the best.

Hi JWP,

I use both FilmGet and ViewScan. The one I choose really depends on the final output of the scan. For example, if I am just making a quick scan for e-mail or web, I usually go with Filmget. It is fast and usually does a decent job without too much color correction required.

If I am scanning for prints, I always use ViewScan set at 4000 dpi / 42 bit. The result is a 120 (+) MB file that is adequate to produce prints up to 13" x 19" on my Epson 2200. ViewScan offers a number of features that FilmGet does not (multi-pass scans, multiple levels of IR cleaning, grain reduction, etc.). ViewScan does require a little more tweaking with color correction but the benifits are well worth it.

Both are well with slide films like Fuji Velvia and Provia 100F (I have to give Viewscan the advantage), but ViewScan does a much better job with grainier color negative films like Kodak Royal 200 and Fuji Superia 200 (in my opinion). My advice is to go to http://www.hamrick.com and give it a try.

One other bit of advice, if you are currently using USB, an investment in a SCSI card would be VERY wise (I use an Adaptec 2930). Your scan times will be reduced in half (or even better)!

I hope this helps.

Thanks Greg for the very useful info. I will try out Vuescan. I scan for prints at 4000/42 bit for prints and have output to 16x20 Iris prints with incredible results from Kodachrome 25 slides. As far as SCSI goes I have my Canon FB1200s flatbed scanner running SCSI but I can't piggy back them as they use different connectors and I don't have any slots left so I will have to see what I can do. I would really like to cut the scan times down though. Again thanks.
