Thanks for the link.
Downloaded than ran it. Seems pretty good. Maximum scans are 3200 lpi, but that's plenty good enough for 4x5 negatives. I like the large preview and scan windows it uses. ...

Rick, those like yours, for example. It's encouraging so thanks for what you said.
I'm still a bit new to large format B&W negative scanning. So I appreciate any help or favorable comments on...
Dan, thanks for the link to Vuescan. I downloaded then installed it. Seems to work pretty good. After making a few more runs with it using different settings, I'll decide if it's worth buying.

Got sent a link with info on updating Epson 4990 Scanner drivers so they can be used with an Epson 3200 on a 64-bit Windows 7 platform by making the 3200 think it's a 4990. Here's the link:

Well, yes, I did mean 300 pixels/inch (ppi) photos for reproduction. I retired from HP almost 17 years ago; 'tain't easy for me to remember all that stuff.
Thanks for setting me straight.
Well, my next phase of scanning 4x5 B&W negatives is using the Epson 3200 I just bought; that is, as soon as it arrives in a box.
It doesn't have the SilverFast software CD, but I'm wondering if...
When I did some technical documents working at Hewlett-Packard, the graphics group standard for printing marketing photos in brochures and such was 300 dpi. As explained to me, that's based on the...
Found this site:

Decent comparisons, I think, to compare different scanners using the same negative.
Nate, thanks for the link to the curves. I understand better now that I've seen the data.
'Twould be nice to see the results of scanning a really good B&W negative at different scan lines per...
Nate, thanks for your excellent post.
I meant 30 line pairs per millimeter in my original post; I know it takes 60 lines, half white and half black alternately positioned, to see 30 of 'em across...
Michael, that's a good question. I'd guess flatbed negative scanners deliver close to specs. If not, then a higher spec'd resolution would best ensure you got at least what your minimum is.
If...
I'm searching for a decent scanner for my 4x5 B&W negatives. Something that will do a good job on negatives with images resolved in the 30 to 60 lines per millimeter range my lenses produce.
The...
When I worked at Hewlett-Packard, a good friend designed chips that were made in the site's integrated circuit facility. Each layer for the chips was made by taking a picture of a drawing of that...
In making a rangefinder cam for my Super Speed Graphic to use with this lens, I noticed a focusing issue. Wide open and focused at distances from 4 feet to infinity as seen on the ground glass,...
Here's a link to a web site discussing diffraction. Best part is a calculator to see how much diffraction a combination of camera properties, viewing distance and f/stop effects diffraction.

Well, I'd ask the factory. Knowing why things are the way they are is the backbone of intelligence.
When I worked at Hewlett-Packard, we oft times were asked why some things were the way they...
Made a P4 cam for my 4x5 Super Speed Graphic from a nail plate. Cutting and griding it for a 90mm Graflex Optar was a learning experience. Hardest part was getting the high/distant end fit all the...
John, thanks for your comment. While this tripod's nameplate's rivited to the main part of the head, I could grind off the rivet's heads, take the nameplate off and see what's inside. That is, if...
Got an old Vivitar 1321 tripod at a garage sale yesterday. Overall, it seems to be rigid and stable enough to use with my Super Speed Graphic at the slower shutter speeds.
It's in excellent...
Here's a picture of an identical lens. Only the serial number on mine's G44xxxN.

I think I'm confused on who made the glass for this lens.
Here's the shutter's nameplate info:
GRAPHEX
FULL SYNCHROMATIC Made By WOLLENSAK For GRAFLEX INC.
...
It's a Wolly version with Full Synchromatic shutter. On the front lens mount:
"3 1/2" (90mm) GRAFLEX OPTAR W.A. f/6.8 No. G44xxxN."
The black round name plate has "Made by Wollensak for...
I agree when the eyepiece is centered in the 4x5" frame. Moving it to the edge shows that old lens is decent enough, especially stopped down to f/22 and f/32. It appears to go down to almost f/45...
Mounted a 15mm eyepiece lens from a spotting scope in a sheet of plywood fit to the back of my Super Speed Graphic. Racked the Graflex 1000 135mm Optar/Rodenstock lens out to get a sharp image in the...
I've got almost two rolls (1 plus another with about 4 yards used) of 48mm wide black 3M gaffers tape. Got it free from 3M via a wholesaler in California when I saw their ad for it on line. Emailed...
Got three square bottles of this for only the first verse of a short song (10 cents each). Question is, can it still be used for developing 4x5 sheet film? The newer bottles are round but this...
Well, this brings back memories of my days in the US Navy (22.5 years of 'em, to be exact). A good friend of mine was a Photographer's Mate First Class at at the time. In 1959, I showed him my new...
About the dark slide's handle/tab color that's supposed to be out if the film under it's exposed, does any film holder's instructions (camera's, too) state what the standard/preffered/proper way is?...
A most interesting thread. Having recently acquired a Super Speed Graphic, I've been going round and round with the "How Do I Mark Film Holders?" issue for some time. In the 1960's, when I had a...
After shifting my Super Speed Graphic's lens sideways to the limits and checking images on the ground glass, I'm rather pleased with image sharpness beyond it's rated image circle of about 153mm. ...
Thanks to all for your comments. But I got to thinking that shifting the lens board from side to side will change the axis reference. I believe that the lens' nodal point should remain fixed in...
Anybody ever set up their large format camera on a tripod, shifted the lensboard to the left limits, focused on a landscape scene and took the picture, reloaded, shifted the lens to the right limits...
The ingenious Hidalgo Don Quixote's a close friend of mine. He's told me several times he has never been found guilty of tilting at windmills. But he did mention that if I use only the smaller 2"...
I don't know. But after reading this:

then doing some optical/lens spreadsheets and focus tests with the SSG's Graflex 1000 Rodenstock Optar...
Yes, I do want to think about how much the film bows. I'll add some approximations to the depth to septum to get the total spread the film may be from specs.
No.
All sorts of work. Includes...
Are you referring to bringing down the flat part of the septum? Or something else?
The ground glass behind the Ektalite field lens is well positioned to get sharp images when the rangefinder's...
In checking the fourteen 4x5 Riteway film holders I've got, some of 'em have septum depths from the flats as much as .201". The 40 year old film that came with my SSG had black .004" thick 4x5" paper...
I used 4 sheets of Ilford film with the camera a couple of days ago for my first live shots indoors with the Graflite flash and 5" reflector. 1 was way too dark; bulb that came with camera didn't...
Dan, I thought about that a few days ago when I made my own shutter tests with a spinning disk. But the spread of errors ranges from 28 to 70 percent in the range I'll use it at. Which means extra...
This shutter's been dormant (stored, unused, set at 1/125th) for about 25 years. Brand new about 1965 in a Super Speed Graphic, it didn't see much use through about 1985. Very few fingernail...
