I scanned a MF slide pair using my Epson 4990 scanner at 2400DPI. Scan
was done with the chips still inside the mount. Film was Provia 100F.
The scene was extremely contrasty with bright highlights and lots of
detail hidden in deep shadows.

I did a simple dust/scratch touchup in Photoshop on both chips and sent
them off to dr5.com to be written onto film using their 8K CRT film
recorder.

The results on the first pass were pretty darn good!

The duplicates were made onto Kodak E100G film. I had a color balance
issue (dupes were warm -- easily fixed on the next pass). The
resolution was 90% of the way there. Looking at them more closely, it
appears my scan is to blame...not the film recorder. The contrast on
the dupe was about 90% of where I'd like it. A subtle digital curve on
the file should fix that.

The cost, $25 per pair. That is not cheap but for those handful of
really excellent images, it is a way of making real transparency
duplicates. Also, because it is a digital process, there is an
opportunity to correct scratches, dust, and other image defects.

I will continue to experiment and let you know anything else I discover
as I work towards perfection.

Best,
Aaron

Sounds promising. What film recorder or service did you use?

Thanks,

John

I sent it to dr5 who runs www.digitalsilver.net

I think they use an 8K Lasergraphics machine with in-house custom profiles.  They can output onto Kodak or Fuji chrome film.

They are very hands on, extremenly technically knowledgeable, communicative towards their customers, and detail oriented.  They can also do B&W transparencies using their proprietary dr5 process.  That is another interesting option.

Once I get the process down with all the parameters perfected, I would be happy to share a folio and the intimate technical details.

I think this also opens the possibility for converting digital stereo shots into MF slide pairs.  This could be a best-of-both-worlds scenario that takes advantage of digital's specific advantages, the advantage of MF-size chips for viewing, and the advantage of backlit transparencies.  Ideas? Thoughts?

I am also investigating some non-traditional (non-wet film) color transparency techniques that appear to offer the necessary resolution.  Printing on inkjet was a failure but there other options.  They may only work for quantity runs (not one off) but may be cost effective if you can justify a 500 quantity run ;-).  More info is coming to me soon on this front.

Stay posted.

As I am doing a lot of stereo HDR images lately the possibility of
converting some of those to MF transarencies is very appealing. However
$25.00 a pair is a bit hard to swallow.

I haven't tried them yet but slides.com will record onto 70mm film for $16 a pair.  Getting better ;-)

Last time I did a run of MF's, slides.com charged me $10 per pair, gammatech.com charged $20 for a few pairs (but said a large order would be less).

Hi

Anyone know where to do it in the UK?

These of course are originals so posting to the US is a bit risky.
