Picking a Scanner for 35mm to Digital (Slides and Negatives)
My thoughts/criteria
Assume:
1. Want good to very good 8X10s

2. Features of the scanner are not so much the issues, as is ease of handling the film/slides. _ have lots of slide and film. Will likely make many 4X6 of Slides
3. All processing done post scan.
4. My budget is low – for this stuff.

What Resolution Scanner is needed? Part of this I like asking the question on Mega Pixels for the Camera. I realize there are a number of other considerations but this I believe is the basics.

Printing 8X10, Good to very Good. – Should all excellent 4X6s and fantastic 3X5s

IF (big if) the image in the computer is super quality (not the limitation) then I believe that a good PRINT can be made on a Good Color Printer at 150 line per inch. – Very good at 200 line per inch and Excellent at 300 lines per inch. (I have an HP Photo Smart, and HP K60 and a Canon BJC 610 – they all seem to “fit” this criteria, but I would invite comments.

So if the printed image is 8X10 then for:
150 the image is 8*150 X 10*150 or 1200 X 1500 pixels.
200 the image is 8*200 X 10*200 or 1600 X 2000 pixels.
300 the image is 8*300 X 10*300 or 2400 X 3000 pixels.

Now how to get that from 35mm negative or Slide
In inch this the image is 1 inch by 1.378 inches - so:

Scanner come in 1200 dpi, 1800 dpi, 2400 dpi, 2800 dpi, 3600 dpi, 4000 dpi & 4800 dpi
Another table:

Resolution Scanned Image
1200.... 1200 X 1654
1800.... 1800 X 2480
2400.... 2400 X 3307
2800.... 2800 X 3858
3600.... 3600 X 4961
4000.... 4000 X 5512
4800.... 4800 X 6614

Well, from this I would conclude that 1800 dpi Scanner should do the job very nicely – if you have good focus, good color conversion etc. etc.

On that basis the Pacific Image 1800u with SilverFast or the 1800AFL by them would be good. They also make a 3600AFL

Question - does anyone have any experience with them??? How is their film/slide handling - quality of scan etc. etc.

Help: I have a 1220U Canon Flat Bed Scanner – but no way to scan slides and film with it. It is 2400 dpi - Darn – any suggestions appreciated. I think the problem would basically – lighting, scan with main light off and provide a light to shine through the film.
PLEASE comment on my above assumptions etc. Thanks for you help.

When I scan 35mm slides or negs I usually want at least a 25MB file. This will easily get me a 24"x36" image if necessary. I can also downsample from there. If I send a file out for drum scanning, I may go for a larger file size.

One can't replace pixels that aren't there, especially if a n image is sent out for scanning.

You first need to understand flatbed scanner resolution. A 1200 X 2400 scanner like you have is usually referred to as a 1200 DPI optical scanner. The smaller number represents the CCD density. The larger number is the number of stops the motor can make in an inch and is basically meaningless. Someone advertised it to put a bigger number on their scanners and everyone has followed or their scanner will look bad to the consumer. There have been people who posted home made film scanner adapters to go on a flatbed, but you wouldn’t be happy with the results no matter how well you made it. 1200 DPI scans don’t make good 8 X 10s

You might have a look at this: http://www.ecost.com/ecost/shop/detail.asp?DPNo=73189&adcampaign=email,ECOSTMYSIMON You can find a decent Tekram SCSI2 card on Pricewatch for less than $20 that will run it fine.

Unless you are scanning mostly 100 ASA film you will find the grain is excessive with a dedicated film scanner. This is true for any dedicated film scanner. 2400 DPI flatbeds have a different light source and tend to not accentuate the grain as much. You can get a program like NeatImage for $30 that will do a decent job of controlling the grain.

Another option is the Epson 2450 flatbed. It allows you to scan multiple images at once at 2400 DPI and doesn’t accentuate the grain as much. Sharpness isn’t as good as a dedicated film scanner but the output is surprisingly good. http://www.virtualtraveller.org/epson2450.htm It also comes with SilverFast lite.

According to how much film you have to scan it might be cheaper to just have them put on a Kodak CD. Most film processors can do that for you and the files are large enough to print 8 X 10.
 
I've done quite a bit of film and slide scanning with my HP Photo Smart S20. I scan at 1200 or 2400 depending on application. I have been very happy with the performance of the S20. I have friends who've bought the new Epson and Canon scanners with the transparancy adapters for slides but they have all been dissapointed with the results. The speed is very slow compared to my S20 and the quality is mediocre.

Sorry, I don't know about other models of slide scanners.

I also have an HP S20 and scan all my slides and negatives at 2400 PPI (the highest resolution) to make master copies. I then create the appropriate sized files from these masters. I use 360 PPI as output resolution on my Epson 1270 printer. 8 1/2 by 11's come excellent.

I have a Canon 1230UF scanner to scan my medium format film with its built in film adapter. The highest resolution is 1200 so I would not use it for 35mm film. 8 1/2 x 11's for these medium format tramsparencies (645 and 6x7) also come excellent.

I'd recommend the Microtek Scanmaker 8700. 1200x2400 resolution, firewire and USB, flatbed + transparency section. The transparency section is separate to the flatbed section, so the scans are not going through the glass and getting distorted by the glass and fingerprints etc. The transparency section takes slides up to 8x10 as well.

Don't expect too much when scanning 35mm film with a consumer level flatbed scanner. It may be adequate for on-screen use and casual inkjet output, but not much more.

Of course, the question of "quality" is very subjective. High Quality output to one person is mediocre to the next.

A dedicated slide scanner, from the usual suspects...Nikon, Minolta, Canon...can produce file sizes in the 30-60MB range. This would be more than enough for highly detailed 8x10's. As mentioned, high ISO film can be a problem.

The PhotoCD service is another option. I'd avoid the PictureCD version, which is more for on-screen use. PhotoCD scans are 18MB in size with 3000x2000 pixel dimensions. Even with cropping, you can get a 10" inkjet print at the sweet spot of 240dpi. On the down side, shops that offer this service seem to vary widely in their quality control.
 
I have the Minolta Scan Elite II which is a 2820 dpi slide and negative scanner. This scanner gives me 9-10 mega pixel files with low compression jpegs in the 2.5 to 3.5 MB. I find this adequate for the 5x7 and 8x10 printing that I do. For good 8x10, I wouldn't want any less resolution. Nikon and Cannon also make good quality, modest priced film scanners. The Elite II has all the features and batch scanning as well. Doing a "batch" of 4 slides makes it possible to set it up and leave for 20-30 minutes while it churns. Do not be put off by the early and often repeated complaints of "banding". I have had no such problems. Finally, I use VueScan software which I find much more convenient than the Minolta software.

A good place to check for a lot of helpful information is http://www.scantips.com/ . Also check out the reviews at http://www.imaging-resource.com/SCAN1.HTM .

I use a PrimeFilm 1800/U negative/slide scanner and it is much better than a flatbed but not as good as one of the Nikon, Canon etc film scanners. I used it to convert all my slides to digital format and some negatives. I usually use a flatbed for scanning pictures - seems to work better for me.

Hi I have just taken 80 35mm negs into jessops to have them scanned and put onto cd £25, doesn't seem a bad does it.

Thanks to all of you for your help - for the references etc.

This is much appreciated.

Does it actually focus on the slide and the negative. the focus point is slightly different. - OR does it rely on depth of field???

How is the color reproduction, brightness, contrast etc. compared to the original.

Thanks once again.

Richard,
Checkout my pbase site to see what a $199 scanner can do.

I'm impressed.

4800.... 4800 X 6614

Well, from this I would conclude that 1800 dpi Scanner should do
the job very nicely – if you have good focus, good color
conversion etc. etc.

On that basis the Pacific Image 1800u with SilverFast or the
1800AFL by them would be good. They also make a 3600AFL
Question - does anyone have any experience with them??? How is
their film/slide handling - quality of scan etc. etc.

Help: I have a 1220U Canon Flat Bed Scanner – but no
way to scan slides and film with it. It is 2400 dpi - Darn –
any suggestions appreciated. I think the problem would basically
– lighting, scan with main light off and provide a light to
shine through the film.
PLEASE comment on my above assumptions etc. Thanks for you help.

...may be more than you want to spend, but I have had excellent results with the Canon FS2710 negative/slide sacnner. I think it costs around $350 - $400 these days. I have some samples at: http://ericksonbird.com/mv/p_reeds.htm

Good luck,
Richard.

Picking a Scanner for 35mm to Digital (Slides and Negatives)
My thoughts/criteria
Assume:
1. Want good to very good 8X10s
2. Features of the scanner are not so much the issues, as is ease
of handling the film/slides. _ have lots of slide and film. Will
likely make many 4X6 of Slides
3. All processing done post scan.
4. My budget is low – for this stuff.

What Resolution Scanner is needed? Part of this I like asking the
question on Mega Pixels for the Camera. I realize there are a
number of other considerations but this I believe is the basics.

Printing 8X10, Good to very Good. – Should all excellent
4X6s and fantastic 3X5s
IF (big if) the image in the computer is super quality (not the
limitation) then I believe that a good PRINT can be made on a Good
Color Printer at 150 line per inch. – Very good at 200 line
per inch and Excellent at 300 lines per inch. (I have an HP Photo
Smart, and HP K60 and a Canon BJC 610 – they all seem to
“fit” this criteria, but I would invite comments.

So if the printed image is 8X10 then for:
150 the image is 8*150 X 10*150 or 1200 X 1500 pixels.
200 the image is 8*200 X 10*200 or 1600 X 2000 pixels.
300 the image is 8*300 X 10*300 or 2400 X 3000 pixels.

Now how to get that from 35mm negative or Slide
In inch this the image is 1 inch by 1.378 inches - so:

Scanner come in 1200 dpi, 1800 dpi, 2400 dpi, 2800 dpi, 3600 dpi,
4000 dpi & 4800 dpi
Another table:

Resolution Scanned Image
1200.... 1200 X 1654
1800.... 1800 X 2480
2400.... 2400 X 3307
2800.... 2800 X 3858
3600.... 3600 X 4961
4000.... 4000 X 5512
4800.... 4800 X 6614

Well, from this I would conclude that 1800 dpi Scanner should do
the job very nicely – if you have good focus, good color
conversion etc. etc.

On that basis the Pacific Image 1800u with SilverFast or the
