 |
|
Since this is a Photoshop forum, every previously existing image that makes it into Photoshop was created by digital capture, of film capture and scanned in to digitize, and some of you might be very skilled at the "art" of scanning. So I think this is relevant to Photoshop.
Can anyone recommend a service to scan in a number of 35mm slides at 4000 dpi and at 16 bit depth?
I have a Minolta Dimage film scanner, which scans in at 2820 dpi. This will give excellent quality prints up to 11 X 14. I have had very high res. drum scans done also, they are very expensive, but the best quality.
I am going to have a number of 16 x 20 Lightjet prints made, so I am looking for something between my Minolta film scanner, and a drum scanner. Something like a Nikon Coolscan would do the job.
Anybody know of a service that can do this? |

shanegoldberg,
Yes, I am aware of the Imacon scan. There is a local lab here that does those. They are almost drum scan price though.
I ended up sending off a few slides to this lab...
http://www.chromatics.com
...for Durst Sigma scans. I think these might be the best quality scans below the drum scan. Their price is okay too, $15.95 for a 4232 dpi scan at 8 bits.
If anybody has any experience with Durst Sigma scans, or this lab, I would welcome your comments. |

they look like a good option, reasonable price etc. i hope it works out well for you. I'd be interested to hear what the quality of the scans is like when you get them back. Keep us posted.

Did you know if thier raw file can be translated by Adobe Camera Raw? It's cheaper and gives you more editing options... if you are able to open it. |

cbadland - Isn't a RAW file one that is solely used for digital camera capture? I have never opened an image in RAW file format, does it have any advantage over a TIFF file?
shanegoldberg - I will be getting these scans back on Friday, so I will file a report on them then. |

The web site you posted said they offer raw files from their scanners.
I would guess that many higher end capture devices (camera or scanner) would have a raw file. Since raw isn’t a format per se, you would need specialized software to translate it into a tiff. Adobe Camera Raw can open most raw files from most cameras, but I don’t know how it would work on this particular file.
There can be many advantages starting with a raw file, it is the (mostly) unedited data from the capture; you can control color correction, exposure, chromatic aberration, sharpening, highlight and shadow detail and bit depth. |

from my understanding raw scans generally means that they just don't do any color correction or make any adjustments to the scan, so they aren't degrading the image and compromising on the quality of the image by deleting pixels etc. they'll still normally save the scans as TIFF uncompressed files or something along those lines.

Okay guys, there has been a communication error here. That website I posted, has two levels of service for scans "Custom" and "Raw"
Custom means they do some editing, and adjustments to the image, Raw means they don't do any editing. Those are just the words they picked to describe those levels of service.
The files are all saved as TIFF's though.
Maybe that was a poor choice of words on their part. How about if they save their Web Scans as Jpegs but call it their "Tiffany" service, or Tiff, for short. |
