I use the HC Combi Plan tank for 4x5, and although our film and
developer combination is not the same, I don't see why the logic
wouldn't be. When I asked a Kodak technician the same question
several years ago, he assured me the small tank processing times I
was used to from roll film processing would still apply, and my
experience bears him out. Tray developing times assume constant or
nearly constant agitation, and tank times tend to assume agitation on
the minute. As long as you retain the agitation strategy you use with
your own small tank processing, you should be fine. For me that's 5
seconds every 30 seconds. The design of the tank may affect how you
agitate, but I find 5 quick inversions works well with TMAX 100 in
D76 1:1. Retaining the same developing times regardless of format is
a real convenience in the darkroom, I find. Hope that helps.

What type of camera are you using? Ron Wisner makes a compelling
argument in an article on his website for placing the Fresnel, ridges
towards the inside of the camera, against the smooth side of the
ground glass, for optimum optical performance. But the fact remains
that many older cameras, including those using the fairly standard
Graflok back, are designed to focus properly with the Fresnel on the
inside of the camera, ridges towards the etched side of the ground
glass. You don't want to tamper with this arrangement, unless you use
some sort of shim of the right thickness to take the place of the
Fresnel, otherwise you won't be focusing on the same plane as your
film. A quick way to figure which way things work on your camera is
to measure from the inside of the camera back to the ground glass,
then put in a film holder, pull the dark slide (no film necessary!)
and take the same measurement again. Ideally, the distances should be
the same. If inverting the order of the Fresnel and ground glass
makes it work, you have your answer. In any event, the ridged side of
the Fresnel always faces the ground glass, and obviously the etched
side of the ground glass faces the inside (front) of the camera.

Provia too, bless them!

Oops, a bad sign post. That's graflex.org!

A follow-up, in case others pass this way...
<p>
Thanks to Tom for the tip on Bill Maxwell, a kind and smart man who
briefly had me ready to replace all the focusing screens on all my
cameras with his clearly brilliant designs. Fortunately I'm not that
flush. To Bill, the whole idea of Fresnels is, shall we say, quaint.
<p>
Then I made the call anyone with any Graflex related problem should
make first, to Fred Lustig, the mechanical engineer in Reno who
bought out the Graflex parts Midwest Photo bought when Graflex went
under. As I told him, he's not hard to find, if you know where to
look. Inasmuch as this forum serves as just such a roadmap for fellow
travelers, his office number (from graflex.com)is 775/746-0111. I'm
giving my back a hood from his stock of reconditioned parts, which
should make field work a pleasure, now that I can see what I'm doing!
<p>
Another happy ending :)

I quite agree this is not a subject that can be adequately covered
here, but particularly want to echo the point that, according to
today's conservation standards (which are changing all the time) no
mounting technique that permanently alters the photograph is
recommended--though I realize many photographers still dry-mount, and
excellent materials exist for this. (Michael Smith's site even argues
that properly dry-mounted photographs may last longer. Regardless,
he's found a new type of board worth investigating--see
http://www.superiorarchivalmats.com/) Unless you're using top quality
board and storing it carefully, though, you're likely to face the
spectacle I just did when curating a show of beautiful bromoil prints
from the 'teens through 'forties: the prints in this quite permanent
process (in which silver is replaced with ink) are outlasting their
mats, sometimes even their paper subsrates. The crummy posterboard to
which many were pasted down (with no help from the likes of Light
Impressions, believe me) were crumbling in more than a few cases, and
taking the prints with them. Imagine what your print will look like
when that acid-free foam core is battered and bruised, then look into
the many cheap and easy techniques of hinging onto acid-free boards.

It'll work, but Azo's slower. You may want to open up!

Someone mentioned a while back the use of Heliars by Kodak for
enlargement. I have an 18cm (f4.5) uncoated Voigtlander Heliar screw
mounted (no flange) into a small (2 1/2") metal board that I'm
reasonably convinced was made as a 5x7 enlarging lens. For b&w
printing, the lack of coating and relatively narrow angle of coverage
should be incidental, and those halo effects might be quite
marvelous. I'd be curious to hear if others know more of this usage;
also of the use of "flat field" process lenses for enlargement.
Thanks.

I've been hunting for a replacement Fresnel lens for the 4x5 Graflock back on my Deardorff, but can't seem to turn one up. Furthermore, I'm told that only one from another Graflock back will fit. I assume this is just a question of size--it's 3 15/16" x 4 13/16" x 1/16" thick. Sorry to bother you all with a shopping question, but it occurs to me someone may have a spare or a lead... I'm tired of seeing scratches whenver I look through the ground glass! Thanks very much -- Stephen

I find these lines at the end of Jack Gilbert's poem, "Poetry is a
Kind of Lying":

Degas said he didn't paint
what he saw, but what
would enable them to see
the thing he had.

Seems to me much of the preceding, with which I naturally agree,
really takes up the question of the relative worth of images by
photographers as disparate as Adams and Kertesz--who happened to work
in different formats--not the value of their negatives, which is
another story. These tend to be priceless, which often means they're
worth nothing at all, in economic terms. They can't be reprinted
without accusations of fraud cropping up (think of the scuffle the
reprinting of E.S. Curtis' gravure plates has generated in recent
years), so from a curator's stand-point, they're a perpetually
degrading resource, useful only for study purposes (for which, again,
they're invaluable). I once asked the curator of a prominent museum
photo collection what he did about negatives. "Avoid them like the
plague," was his reply. It might even be argued that the value of
prints of certain collected images increases in the absence of the
negative, as it does in the absence of the photographer. To my
knowledge, the Center for Creative Photography is the only museum
collection of fine art photography that actively acquires negatives
as well as prints--though there certainly are exceptions (MoMA's
Atget negatives come to mind). Adams is exceptional here too: I
believe he left his negs. to the Center with the stiplation they
remain available to students to print from, modestly suggesting, they
may as well learn from the best. At first I was stunned by this
generous invitation to allow other photographers to forge potentially
valuable prints from his negatives. Then I realized it was a dare--he
knew full well no one could make his prints, not even from his
negatives! The negatives alone are a score without a sound.

An upside is less bellows flare. Apart from weight, I don't see any.

Haven't used it myself, but I understood a few years ago (from
Patrick Alt, who made a lovely camera at this size) that Ilford was
coating at least one of their b&w films in 4x10, though I haven't
seen it distributed in this country. Robert White, the British
dealear, ought to know. When cutting down film, remember to measure
the actual size of the film, which is generally 1/8" shy of its
reported dimension in each direction (so it fits in the film holder).
Naturally, you want to replicate this scenario with the two halves.

I suspect the collectors and dealers who benefit most from this
system would hate the idea of numbering prints from each session.
Without detailed knowledge of a photographer's work, who's to say how
many prints are out there? That, after all, is the issue, from their
point of view. Clearly it's quite different from the photographer's.
<p>
A "vintage" print, in practice, often means a print made before
editioning was expected. So, early prints by many name photographers
are uneditioned. Perversely, this often makes them more valuable,
since no one knows how many prints are out there... This example
should prove photographers have more leeway than they often realize.
<p>
Many photographers operatng in today's art world have chosen
processes with built-in uniqueness--Polaroid, and even its grand-
daddy,the Daugguereotype. Or "alternative" processes where no two
prints are likely to be just the same. Which raises the point that an
edition doesn't need to imply that all prints in the sequence be
identical in every way. In many alternative processes, there would be
inevitable shifts of tonality, etc. Seems to me a lot of this is
about the tug-of-war between the hand and the machine made.
Editioning as it's usually practiced means assembly line printing. If
all the prints in an edition had slight differences, showing the
touch of the printer's hand, I suspect dealers would find a way to
ask more for them. But remember, although editioning may allow
contemporary photographers to command higher prices for their work
(even though many of those "editions" are never printed out), it's
not the photographer who sees the most inflated prices this system
allows. It's whoever resells those prints whose scarcity has been
assured--the auctioneers, collectors and dealers of "vintage" prints.
<p>
It's easy to see why photographers not operating in this rarefied
arena might prefer not to bother with it. It would be heartening to
see more photographers bucking the editioning trend, since most of
them are not likely to experience its benefits first hand.
Unfortunately, it seems too many feel they must edition if their work
is to be taken seriously. Their prints would remain more affordable
to more potential buyers if they did thing things the old fashioned
way and printed on demand, or as the spirit moves them. Epistle over.
-
Now, if you're really serious about the business of editioning, it
seems to me you have to be willing to "cancel" the negative at the
end of the run (unless, of course, you're holding out for another
version, perhaps in another size or process...). Who's ready to take
a hole punch to that precious negative? Seems to me that willingness
to destroy one's own work in order to make it is emblematic of the
degree to which photographers have had to put themselves in the hands
of the art world to make a living, when they do. (Sounds a bit like
Abraham and Isaac, put that way, and maybe it is.)
<p>
Walter Benjamin thought photography's revolutionary cachet lay in its
extreme reproducibility. The old habit of open editions paid lip
service to this ideal, though the point is well taken many "master"
photographers had next to no market for their work. I love fine
prints as well as the next bloke, but it's sobering to see the
predicament we're in, in this art world photographers fought to enter.

A while back someone asked for directions to Ken Hough's Deardorff
website. Here it is: http://deardorffcameras.0catch.com/
-
He's prominently quoted on Ron Wisner's website praising his Wisner.
He's still at it, by the way, unless I've missed some bad news.

Thanks for the tip, Bjorn. If anyone knows where I can find one of
these, it would really make my month.

I hate to get in the way of a good idea, especially one that has me
wondering whether your low volume is the film or the short wave (or
was it that slow-motion phonograph)! But for developing 4x5 film
without a darkroom, I've found the HP Combi-plan tank (available from
Calumet) a heck of a lot easier than an engineering test. (They're
also light years ahead of the old Yankee tanks, which are just fine
if you only need to develop some of your film some of the time.) Even
with a darkroom, this beats tray development for small amounts of
film since you never scratch a negative, and you can use tank
development times. I checked this thread because I'm always hoping
someone will come up with a comparable system for 5x7--please tell me
if you know of one. Even called HP's distributor recently to be sure
they didn't make such a thing. They told me, if I wanted 5000. Which
leads me to ask, are there 4999 of you out there who'd buy one? 4998?

Sounds like a resounding chorus of praise for the Durst, but just in
case you hadn't noticed, Calumet has a slightly used Zone VI 5x7
enlarger head on their website currently. Sorry, I can't recall which
type, and frankly I wasn't able to figure how much of the outfit they
were selling (I think it's more than just the head, but perhaps not
the whole rig) when I looked into this a bit myself yesterday. It
might even out the prices, even if it complicates your decision.

Probably not an issue on top-notch contemporary lenses like the ones
you've mentioned, I agree, but those of us using some of the many
fine older lenses out there wouldn't want to go too long without some
sort of shutter test--whether of the do-it-yourself variety, or the
sort performed by experts who can actually repair slow shutters, or
tell us how far off they may be. It's an argument for barrel lenses,
I suppose, but if you're calibrating equipment for zone system work,
this seems an essential step. Even new shutters do vary somewhat.

Devoted as I am to my Deardorff, I've admired the Ikeda 5 x 7 I
periodically see on eBay. Of the contemporary Japanese wood fields,
it's the only one I'm aware of in this size, and often not terribly
expensive, though that seems to depend -- as with the Deardorff.

Patrick Alt in L.A. works on Deardorffs, as Ken Hough does in the
Midwest. Either could do better than a cobbler, is my hunch. Best,

looking for Mr. Metal Master
in Large Format
Posted
I wonder if anyone knows how to reach the Long Island, NY company
that I gather still makes the Hoffman Metal Master 8x10 film holder?
I'd also be interested to hear from anyone experienced in its use. I
assume these are more rigid than ordinary wood or plastic holders.
