I'm surprised you were able to make a coating. We never though of it. Congratulations. The point is to denature the albumen coating (variations on through beating). Evaporating the water from a...
I don't use the devices supplied. I take a mechanics 6" steel ruler (1/2" wide in 1/100" and mm). Turn in upside down and raise the 6"-end 6mm off the platen using a 6mm stack of PostIts. One mm...
I think I read the coating reference on the Schneider website, maybe in Wikipedia (but then I get a second source). Maybe I did confuse single sputtered coating and multi-coatings. The words are...
Please give some references for that.
I got my statement for many online searches. Books and The Schneider data sheet and website. I may have gotten some competitor disinformation on...
You know that large format lenses were uncoated until the 1980s. Schneider's for sure. That means unnecessary scatter from each air-to-air interfaces, the blacks will suffer.
Assuming a medium...
I had forgotten about Fuji Crystal Archive. I used it way back, but it had only a small share of the market because Kodak had the market locked up.
I have a colleague (in Aptos, CA) who used...
Look at the reports on WIR. Henry Wilhelm has been evaluating imaging materials since the 1970s. WIR has amassed the most comprehensive array of answers to your seemingly simple question.

Most historic sheet film is on acetate base.
Much modern sheet film is on acetate base. Some modern sheet film is on Estar (Mylar) base.
People don't like it Estar base. They like acetate...
Glassine is no longer recommended. Ther is plenty of acid free and even buffered glassine available . Made into envelopes I don't know.
Clear plastic is the new recommendation.
Kodak used...
Where does Ilford out source to? China?
Sorry to piggy back on this discussion.
But, you speak of Kodak's "contracts." What is/are the extent of Kodak's commitment to future production of MP film.
Clearly pro/sumer still film will...
Maybe I'm not following the discussion. Sorry.
The first thing that came to my mind, having made albumen paper prints and salted paper negatives <http://albumen.conservation-us.org/> years ago,...
I've heard of these (generic) fabled lenses. Thanks for all of that.

Right, my friend couldn't find large format lenses beyond 80 lp/mm, and 100 lp/mm seemed to be vaporware. I saw some of the tests and they just couldn't hold up.
Is there some application that...
I have a friend who used to manufacture digital scanbacks. He tried to commission a lens that could match 10,000 pixels per 2.67" (3750 ppi). He couldn't find a vendor to do the job. Expensive...
If you could get a digital scanback on your view camera with that lens, you can check alignment by going to very high resolution on an area of high contrast and checking the red, blue and green...
The problem with this technique is that you loose much of the fine detail and low density gradations. The image becomes more contrasty and much less like the original. The tradeoff is that you now...
Seems to me this has been discussed before.
Opening the aperture softens the image, we know the results. I'd make a series of tests on a relevant area of a particular negative (or several...
I'm online, what is it that needs to be added to the discussion?
Tyler came and got me. I know Lenny and Sandy well.
If you don't match the aperture to the resolution, you loose resolution....
I have a 9600 which has seen moderate use and has been a continual excellent performer; I'm the original owner. I had one ink that was showing only 6-10 dashes and no solid lines and another with...
The other advantage of the tabloid sized 10000XL is that it has automatic and manual focus. This is almost unheard of these days except on equipme cost 4+ times as much.

Paper,...
Most Japanese papers are acidfree, being made from high quality materials. There can always be exceptions in this new world of “machine made” Japanese paper. Formerly, before the mid-1980's, the...
Get a 1/16" thick piece of Plexiglas from you local plastic's store. Use VM&P Naphtha (1 pt from Home depot is under $5) to wet mount the plastic sheet on the glass platen of your V750. This...
I'm not sure of the look you are going for, but Japanese style binding does not go with a coated paper, let alone a thick western paper. The book will be hard to open. In general, that binding type...
I know of two causes for the ripples. One has been mentioned: excess moisture generated by the heating of the print and/or mountboard. In low humidity environments preheating is often not...
Color alone is not an identifer. Developed-out-print[s] (DOP) generally have a neutral to slight greenish tone. Collodion, in general, have a more purplish tone. None of this is hard or fast, just...
Prints have much less resolution than the host negative. A modern print only needs the resolution of the "human eyes" seeing it, or roughly 300 ppi (6 lp/mm). Thus, I scan at 600-900 ppi to be sure...
I'm not sure I follow. You want a 40:1 enlargement, but you were scanning at 3600ppi, where the multiple would be 90 ppi, or approximately screen resolution.
The human eye is roughly capable of...

Thanks! Nicely done.
The best way to store film is in cold storage.
Sheet film used acetate base until about 2000; Kodak went to all Estar in 2000-01; don't know what the others have done, assume acetate base. Roll...

Thanks for that reference. I found it on the (a) 3rd line in the GT-X770 page and (2) the last page of the GX-series PDF. Is there any other source? It seems the LEDs are only on a machine...
Are you absolutely sure that you purchased Epson brand ink? Purchased from a reputable distributor such as Digital Art Suppliers, that Epson could take to court.
I have bought inks for lesser...
Both RAW and DNG use 16/15 bit when processing images.
I didn't see the comment about using "compatible” inks. That is the first place I'd look. If you can afford it buy a full set of Epson 110 ml carts to test if there is a difference. Please report...
Go to the Epson Support for the 9600/7600 and download the special profiles made by Bill Atkinson for the 2000-era printers.
If you are already using these fabulous tools, then there is either a...
Where do you see those Nikon claims for 5000 lp/mm?
Many thanks for the references.
Love all that resolution data by Perez in the "4 camera" essay.
Would it be reasonable to say that 35mm & MF lenses can't do much better than 120 lp/mm.
