4George De Wolfe - GF usage

4George De Wolfe - GF usage

2001-08-19 by Julian Thomas

Hi George,
After my qs to the list re what to do with an epson 1680, I've now got your
article from Camera Arts. I have 2 questions: why do you say that it is
important not to allow the scanner software to set a size, but to output at
100% and resize in GF? Also why is Silverfast so vital as opposed to
something like Vuescan?
I normally use only BW 35 film (now changing), printing to Piezo. I scan at
4000dpi 16bit 'raw' and allow Vuescan to give me a file sized at about 12in
max width (about a 20meg file). I then save in GF and up or down the size
slightly from there. I used to use an older version of Silverfast (which I
paid for!!) but wasn't happy with the raw scans.

Julian,

I am sorry to report that George has left the group as well as the 
Piezo group overwhelmed by the volume of posts the two lists 
generates and the demands of his own schedule. He is still on the 
Piezo Pro list, which I gather is by invitation only. He will be 
missed. He is a great guy. If you go back to one of his posts on this 
list, open it, and click on his e-mail address you can send him a 
message directly. I would say your chances of an answer are high.

In the meantime I will take a shot at your questions:

I believe that he wants you get the exact optical resolution out of 
the scanner. Genuine Fractals will no a much better job of resampling 
your files that any resampling software either Vuescan, Silverfast or 
whatever. I think he is speaking of resampling not resizing.

I am not quite following your next quesion and you may be mixing scan 
dpi, final print dpi and print size. The important thing is the scan 
dpi. If you don't resample, the file size stays the same no matter 
what the print size is.

I have not worked with GF but from what I have read this is a step 
you would apply just prior to printing and would not necessarily save 
to your primary file but perhaps to a print file for a specific sized 
print.

I would take a raw scan from Vuescan, resize it without resampling in 
PS, do all your manipulations, save this as a master file. Prior to 
printing resample using GF, sharpen if desired and then print.

I know George is a big fan of Silverfast and I like it too. That 
doesn't mean you can't accomplish the same things with different 
tools and workflows. Since you will have both, you can try it each 
way.

Hope some of that helps.

Martin

Re: 4George De Wolfe - GF usage

2001-08-20 by Antonis Ricos

For the sake of anyone else following this thread and George's 
recommendations regarding Genuine Fractals, here is an older message of 
his from the Piezo list:


>>>>>>>>>>>>>>>>
  Message 8354 of 8396
From:  "George DeWolfe" <dewolfe@m...>

Subject:  Re: [piezoBW] Piezography and Genuine Fractals



OK,OK
If you have a drum scanner, you don't need Genuine Fractals. 
You will need it for the Imacon Flextite, however, if you go up to 
16x20, because it's not a true drum. If you have any other type of 
scanner - flatbed with transparency unit or film scanner, and you 
are scanning negatives or transparencies - you need Genuine 
Fractals. 

This is how I scan:

1)  Scan 4x5 @ 100% with a minimum of 720ppi.
      Scan 120 @ 100% with a minimum of 1000ppi.
      Scan 35mm @  100% at maximum scanner optical            
resolution.
2)  Edit image.
3)  Save As Genunine Fractals and "fractal up" to the size print 
you want, at the original resolution(the one at which you 
scanned). At 16x20 or 13x19 your files will be large(some of 
mine are 200+ MB). You CAN Unsharp Mask a small amount 
after "fractaling up."

I have Genuine Fractals Print Pro version, but the smaller 
Genuine Fractals works ok, too. The only difference is that the 
smaller GF handles only grayscale and RGB files, while the Print 
Pro version includes CMYK and Lab.

John Santoro at Apple told me about this software when it first 
came out. I couldn't live without it on my "ordinary" Espon 
1640XL.

Buy it!

George

Otherwise, Julian, I think Martin's answer covers your GF question.

Re: 4George De Wolfe - GF usage

2001-08-20 by Martin Wesley

Tyler,

Actually this is supposed to be where it excels. The reviews that I 
have read indicate that it is no magic bullet to get a 4000 dpi scan 
from a 1200 dpi scan but if you need to go from 4000 dpi to 5000 dpi 
it is much better than the bicubic in Photoshop.

You are right. An Absolut mental blackout on my part.

"Does Genuine Fractals 2.0 and PrintPro support 16-bit Color? 

We do not currently support 16-bit mode with our plug-in. We suggest

Martin (and Todd), thank you for going to the trouble to look into that, if I weren't so lazy I could have found the info myself.
My interest in the product hasn't been great, only because I'm not sure I need much larger files for better prints. But at this 
point I'm very hooked on a 16 bit workflow.

I'll post my workflow soon, I need to write it in a way that is
concise and doesn't get too long. It's pretty classic Culbertson 
CMYK with PressReady.
Here's my nonsense about 16 bit. No matter how much I try to perfect
this stuff, or which workflow or driver I try, I can take 
what I thought was a great print that makes me drool and be suddenly
let down a touch when I put a great platinum or silver print next to
it. Traditional methods are truly continuous tone, objectively and 
subjectively. Inkjet prints are not strictly continuous tone and I
think it can be sensed. I don't care how many articles you direct me
to about how many levels of gray humans can detect, and how these
prints far 
exceed it, I can see the difference. It's part of the power of the
best photographic prints for me, and it's still not quite there. I
love these prints and intend to continue with quads, I can do things
with these 
images now that come much closer to what I was after. But there does
seem to be this trade off, and I'm still not positive it's worth it.
I'll do anything I can to minimize that difference, even if I'm not
sure it's helping. A 16 bit workflow results in obviously 
superior histograms at the end of the process. Whether an RGB or CMYK
workflow, these things have been jacked pretty heavily by the time
they're really well separated for the best prints, and 16 bit helps a 
lot. If any part of the workflow converts to 8 bit, even if it
converts back again for the sep stage, you'll see a difference in the
histo.
You could argue it doesn't matter, the drivers all remap the pixels
anyway before sending ink to nozzles. It you reres your 
image in photoshop, you'll see your histos get smooth again because
some averaging has been done. It's very probable the dithering process
does the same thing to some degree.
With some images, I can see a difference with 16 bit from scan to
print, with others maybe not. But rather than spend 
precious time testing the theory, I'd rather just print this way to
make sure I've done 
nothing to further destroy that illusive dimension in the prints. It
was hard enough the darkroom way!
See, I told you it'd be too long.
Why don't these lines ever wrap right in Yahoo?

Tyler's Workflow? was Re: 4George De Wolfe - GF usage

2001-08-23 by Martin Wesley

Tyler,

Thank you for the rough outline. I completely sympathize with you on 
the traditional methods. There are some real trade offs here. I keep 
hoping to here more about producing digital negs, contact printing, 
etc. The group and the market seem totally focused on inkjet but I am 
hoping for some other options.

I hate to point you down this road as it is full of pitfalls and 
raises new questions, but have you tried varnishing a print yet? I am 
not exaggerating when I say that a varnished Museo, Schoellershammer 
Velvet or other similarly surfaced inkjet print takes a quantum leap 
toward traditional B&W media.

Your lines probably are not wrapping correctly due to some mismatch 
of screen font size and resolution, as a guess.

Well here's an idea I haven't had time to pursue. Lightjet and
similar processes write digital info to continuous tone print 
materials. I inquired with the local pro lab, and they showed me a
clear film material that can be used with the process, 
probably used for overhead projections or other kinds of backlit
displays. It would take some calibration, but why not 
output a negative on it for contact printing? It's not that expensive
considering many prints could be made from it. Seems 
like it would be superior to the imagewriter options people are
trying because it's not dots, it's continuous tone film being 
written to with light. It'll be a long time before I get around to
trying it, it's a thought.

Nope but I'm interested. Another thing somewhere on my list...

Tyler,

When you get the urge check the archives on Phil Bard's work with A&I 
using the LightJet film recorder to make an enlargeable 4X5 from a 
digital file, Steve Meyer's work making negs from scans of X-ray 
using an LVT recorder and then there is always Strange Ross's digital 
to photogravure technique.

Print wax. I'll have to check that out. Maybe on top of the Varathane.

Had to change that subject line Martin.
Have done LVT tranparency output for commercial work but never 
enlarged one. I was thinking more for platinum contact prints at
sizes too big for LVTs...
Gravures can be gorgeous, I think quads bear closest resemblance to 
them.

Some where I heard there was a "grain" to the Duratrans film that 
caused problems. Allen at Lincoln Inks is working with Dan Burkholder 
to make contact negs using their dye inks on an Oce material that 
would fit in a 7000 or maybe even a 9000.

The stuff I saw didn't appear to be duratrans, which usually has a 
white but translucent base. This stuff was a clear film base, the 
grain was only visible with a loupe and was very small, would only be 
an issue if enlarging, if then.
Making contact negs with Epsons introduces the very part of the 
process I suspect needs to be eliminated, dither, not contiuous tone.

Do you recall the name of the material? Also I would expect a ditner 
patter with the LightJets which I believe print at 300 dpi but 
perhaps by being able to vary intensity on a silver emulsion do a 
better job of hiding it.

I agree. Everyone should check out his site and see what can be done 
without a lens!

OK, I dug it out to take a look so I can stop talking out of my butt. It was printed with a Durst Lambda 130, the file is 200 ppi (I 
think I was told the printer is limited to 300 ppi files, fine for contact not enlarging), and the "paper type" is labeled 
ilfoclear2000 43F401 01/12. Obviously Ilford. I don't see a dither as such, under a loup I see faint precise lines, probably 
some kind of head travel, invisible to the unaided eye. It really does look pretty darn continuous tone. Dmax looks pretty 
high, but without testing I don't know if it's high enough for full range platinum.
Another thing to put on the list I'll throw away at the end of the day...

Where can I find the "Wolff" curves that I read about in several 
postings. Would like to try them out.

Curves

2004-12-15 by Fred Drury

Hi ...

My name is Fred Drury and I joined the group earlier this week shortly after 
I began experimenting with QTR and saw a reference to the group at Roy 
Harrington's website.  I certainly find the discussion on the site of 
interest.

I am using a Dell Dimension 8250 system with an Artisan monitor setup in a 
dual screen mode so I can put the pallets on the secondary screen.  I print 
on an Epson 7600 and 2 Epson 3000's (which are shortly to be replaced by an 
Epson 4000).  I am using UC inks (currently matte black) on the 7600 where I 
am using QTR.  I have a GretagMacbeth Eye-One Photo system and use it to 
create profiles as necessary.

I am interested in learning more about QTR.  In particular I would like to 
learn how to create my own curves ... just now I am looking at printing some 
IR (film) images.  I have been testing with EEM, but think I would like to 
try on Premium Luster.  I would appreciate some help and instruction on how 
to go about the creation of a paper specific curve.

Thanks in advance for your assistance.
