Hello,
Been there, done that. I used to set up a table over the toilet and put the enlarger on it. A board on the sink for the trays and a large was tray in the shower. Used it for years. But one...

Hello
I own an Analyser Pro since a long time. (I do not do much darkroom work lately, but I used it a lot). It is a wonderful piece of gear and one apt to save both on time and money.

Hello !
I've got 100 sheets of Agfa CP-BU New and a 100 more of Ortho CP-G Plus both in 18x24 cm size.
As I was printing in my darkroom, I souped one sheet of Ortho in the tray of Bromophen...

Hello !
I doubt that. Mercury had been internationaly banned (like the gas in the fridges causing the ozoone hole)
Maybe one maker/distributor had a bunch of New old stock, but it should be gone...

Hello !
Gossen used to sell the successor of the Luna Pro until recently. They have devised a little adapter holding two silver oxide batteries and making, with the aid of a micro circuit, an exact...

Hello Guys,
I plan to go the X-Ray film route.
In the last couple of days, I've read the whole of this thread. Now, I'm confused.
May I ask if you can put up a digest for me, done by the Master...

Hello !
I own the Laborator 1000, 4x5 version of the 138. (same vintage). As I'm living in Europe, I need 220V bulbs. And they're out.
So I made experiments. Durst state that the 150 and 300 W...

Hello !
I'm the other side of the pond, so consider my comments accordingly.
You are worried about customs fees. They are expensive in Europe (when buying something which come outside of the...

Hello !
I've got a PDF file of the French version of the maintenance manual. The schematics are present and some oscilloscope traces to show the various signals.
I can't attach it to the forum as...

Hello Bill,
I own and use a marvelous piece of gear : the Analyser Pro from RH Designs.
It does just that. It knows the sensitivity and contrast range of the paper you put on your easel, and it...

Hello Pablo,
In France where I live, there is a saying that the first camera you get won't suit you for long. So at one point, when you've practiced enough, you'll want to change the camera !
If...

Hello !
In the early 1900's, photographers used the camera as the enlarger. The light source, then, was the major problem.
Now, with cold light and LED available, it may be the easiest part to...

Ask Aurélien !
I've no clue about this.... I only use 4x5 !

Hello Aurelien the French owner of the company "labo-argentique.com" has privileged relation with Rollei.
He asked them if this film could be cut in various sizes including ULF during the next run...

Hello Robert,
I'm fortunate enough to own both the the 135 and the 150.
Yes, both are useable for 4x5 work, the fact is that you will need less column height to enlarge big using the 135...
P.S....

Well Chauncey,
This recommendation came from the book by Gordon. I must admit that my copy is old,so maybe it has revised the capacity.
My advice was for hand processing, when using a Jobo I use...

Funny, editing my post to correct typos, it gets duplicated...

Hello !
First of all remember that Jobo printed quantities are absolute minimum to wet all film in the tank.
Depending on the chemistry you use, you may need more than that (i.e. PMK need 500 cc...

Humm Michael,
Your comment seems "Shadock" logic to me. In France in the 60's we had a TV series of cartoons where the main characters had been "the Shadocks". They planned to send a rocket in space...

Nikor in the USA made stainless steel tanks and spirals to develop film. In any size.
They had a very nice spiral devised to hold 12 cut film sheets which was adjustable from something like 6.5 cm...

Hi Keith,
I own one MOD "reel" to fit my Paterson tank. I experienced mixed results with it, so I reverted to the Jobo 2551+ 2509 for 6 sheets or the Nikor stainless steel for 12 sheet at a time....

Actually I did not make the timer.
I was going to shop for the components when I saw a kit for a ready made timer, with the power relay, for a couple of Euros. I bought it, and soldered the...

Hello !
Jobo has standardized on parts in order to reduce costs.
The center cores share all the same diameter, and same length. Same aply for the funnel or bowl to hold chemicals in the film...

Hello,
I for one would keep the brand I've the most lenses of.
why ? Imagine you're planning to make an exhibit, and you've to print negs in various sizes and age, having the 50 the same brand and...

A wheel cart is the way to go. In France some fools do this...
Carrix has products for this, with THE price tag...
Have a look also at high end baby trolleys with inflated tires or shopping carts...

Hello !
IMHO standard lenses (by standard I mean lenses of the "normal" focal lens for the format without extreme opening or coverage power) are good and very good since WWII.
In that focal lens,...

Hello !
I own an MPP MK VII and a Sinar Norma. Guess what , I use the Norma in the field so much I've leaned the MPP to a friend instead of seeing it gather dust in the closet.
The 4x5 Norma is...

Hello Luigi,
I've digged up the documentation of the old Schneider Angulon (the 6.8 version, with very small lenses).
They state that there are 3 focal length available with this lens : one with...

Hello Luigi,
The older Sironar, like the Symmar from Schneider are convertible lenses. More modern designs are not useable in this way.
You normally unscrew the front element to get a little less...

Than you Jon, this is the best I've seen so far, seems different from mine, but it will help.
I've to devise the way to put the blades back in place at first...
This seems tricky.

Hello !
The jobo tanks are modular. The 25xx series share the same bodies as the 28xx paper series.
So if your tank is too short to rest on both rollers, add a tube of the 28xx series to make for a...

Hello !
Get a tube from a bicycle and cut a square in it.
Use the square rubber pad as a "glove" to help your hand stuck to the front element and it should help you unscrew it ! (at last you would...

Thank you Domaz, but my problem is the exact reverse. All parts are loose and I want to put them back in the box in the right place ...
And it is somewhat complicated ;-)

Hello !
I've been given a size 0 Seiko SLV shutter in kit form.
As far as I know, all parts are here. But without any documentation and dismantling knowledge it's a hard task putting all parts back...

Hello !
Linhof had film holder with a pressure plate. As I own a couple in 9x12 cm (the European version of 4"x5").
They are double film holders, with levers to extract the sheet film. The only...

Hello !
If I'm not mistaken, the F-stop difference is only a different scale fitted into the slot.
As the knob actuate the push pin for the DB mount lens, you select the scale corresponding to the...

Yes. I tend to favor a very heavy gage of cotton thread because it produce less lint.
This method is used in the Agfa's Isolette I and II to seal the back from light leaks.

I don't know. What I'm sure of is that someone I trust has been demonstrated the full documentation of the Sinar Norma at the Arca Swiss factory in France.
He told me that the whole bunch was very...

Hello Grant,
I can ascertain that Arca did actually make the norma. they still have the blueprints and drawings. If I'm not mistaken, the Norma prototype was not working (and unable to) when Mr...
