: Found this recipe posted in a "Rodinal" thread from
: another Photo newsgroup. It seems to describe how to
: make your own rodinal from common household items easily
: obtained from chemists/apothecarist/drugstores
: (whichever word applies). I hope I did not violate any
: copyrights by doing this:

: 50 g sodium sulfite
: 20 g sodium hydroxide
: water to make 250 ml
:
: Start with about 150 ml room temp water. Stir in the
: acetaminophen and sulfite (I used sodium sulfite stock
: solution I already had); solution will be nearly opaque
: and white. Don't worry about the little rags and tags of
: tableting material; they don't seem to affect anything.
: Add the sodium hydroxide, stir, seal, and let stand for
: at least 24 hours; activity may continue increasing (as
: the reaction converting acetaminophen to p-aminophenol
: proceeds) for up to 48 hours from mixing. If the
: solution isn't as dark as weak tea with milk, at a
: minimum, it needs to stand longer.
:
: As solution ages, you may note a layer of less opaque,
: darker colored solution floating on the denser, chalky
: looking portion; stir this together before using. After
: about a week, clear needle- like crystals will
: precipitate; leave these in the solution and stir before
: drawing off concentrate for use. Color will continue to
: darken from tan, to pink, to brown; as with Rodinal,
: this does no harm.
:
: Dilute like Rodinal, use Rodinal times, though use of
: the sodium salts instead of corresponding potassium
: compounds in formulation is said to result in "softer
: working" developer, so if you're already a Rodinal user
: you might find you need to adjust times slightly to keep
: the same contrast. Don't attempt to use 1:100 until the
: solution is at least pink.
:
: This formula originally comes from a discussion thread
: on rec.photo.darkroom newsgroup about two years ago,
: BTW, though the poster then cited another worker whose
: work I haven't seen. I'm sold; if you buy the
: acetaminophen at Costco, use Red Devil brand lye, pay
: $5/lb for your sulfite, and buy distilled water at 97
: cents a gallon, this developer costs about 55 cents for
: the above quantity, which will develop about 50 rolls at
: 1:50 (35 mm or 2x120 on a 220 reel). Use of distilled
: water for dilution will, of course, increase cost per
: roll for the working solution, but it's still around 25
: cents a roll; I usually factor out the distilled water,
: since it's essentially a constant for a given amount of
: film. Fomapan 100 gives *excellent* results in this
: soup; TX and Classic 400 in 120 are pretty nice, too,
: though the grain might be objectionable in 35 mm. I've
: been using it at 1:50 with reduced agitation, adding 0%
: to published Rodinal 1:50 times to account for agitating
: every 3rd minute.

: I tried to brew today this Rodinal substitute
: formula. It mixed as the recipe described it. The
: brew I got presently looks similar to (and has the
: consistency of) Tabasco Sauce :D It will need two
: days to 'ferment' so I couldn't test it with film
: yet.
:
: To see if what got brewed was really a developer of
: any sort, I put a drop of the freshly mixed "sauce"
: on a piece of bromide paper. The spot where the
: solution landed darkened in seconds, just as what
: would happen if Dektol was dropped on it. To test
: it even further, I made up a 1+30 diluted solution
: and half-dunked another strip of bromide photopaper
: in it. The submerged portion 'developed' to a
: perceptible grey in 2 minutes, and darkened to a
: dense grey in 6 minutes. This is exactly how paper
: behaves in diluted film developer.

: This "rodinal" formula seems to be promising....

: Used it to develop Chinese generic ISO 100 BW film
: exposed in my Leica M3 with a Jupiter-3. Subjects
: were my studio cats. Cats, being furry and frisky,
: are the best readily available test targets for
: testing resolution, focus, film grain, etc. This
: Chinese BW film is by nature mushy.
:
: The film was developed at 1+75 dilution (I initially
: planned 1+50, but added too much water in the mix),
: using Agfa Rodinal instructions. The resulting
: negative was a bit on the thin side, a bit
: underdeveloped since I did not have a starting point
: for the developing time for 1+75. Looking at the
: negatives, they look every bit like similar Chinese
: generic BW films I developed in real Agfa rodinal.
:
: The developer is fermenting in the way the recipe
: described it. It's getting darker at the top. The
: original Tabasco sauce colour is going Coca cola.

: The DIY Rodinal is now taking on a brownish, syrupy
: appearance. I have a bottle of real Rodinal close
: and the contents of either bottle are beginning to
: resemble each other. It might be a week before the
: DIY Rodinal becomes ripe.
: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
: Another update- my 2 day old brew (its supposed to
: be fully "ripe" after 48 hours of mxing) is behaving
: even better. The 500mg x 30 pills /250ml formula
: seems to yield the most Rodinal-like concentration
: compared to the other formulas found in the net.
: There are a lot of alternative paracetamol-based
: formulas which call for as little as 6 pills and the
: resulting mix is always subject to the question of
: what sort of dilution should be used. Dilutions of
: 1+1 or 1+10 have been suggested for these formula,
: with corresponding times- dilutions and times
: uncommonly associated with real Rodinal development.
: While they may work satisfactorily, the strange
: dilutions and times can be confusing and distract
: from the 'feel' of developing with Rodinal.
:
: The formula I tried can use the recommended
: dilutions and times given for Rodinal. For today's
: test, I used a 1+40 dilution following the
: recommendations given for ORWO R09 (found my copy of
: the old ORWO Rezepte). Developed was a roll which
: had been sitting inside a Rolleiflex 1a for more
: than 3 years, film itself expired in 2003. There
: was some fogging (same could be seen in similar
: rolls developed in real Rodinal), but the resulting
: images are still printable. Maybe an addition of a
: bit of Bromide (less than 5 gr in the concentrate?)
: should arrest the fogging.
:
: Maybe your local highschool chemistry lab can give
: you some sulphite? It's not expensive here- the
: local chemical supplier here will sell a minimum of
: 500 grams and it costs only about US $0,75 for a 1
: Kg pack. Sodium metabisulphite is a bit more
: expensive at about US$1,30 /Kg. If shipping were
: not problemat, I can send you some. :-)

: That film was developed in the paracetamol derived
: rodinal developer. Its been two months since the
: solution was brewed. The colour is now dark, like
: strong coffee or Coca-cola. And it's been lying
: around in its amber bottle, in tropical (it averages
: 30 C now here) climate. The developer is going as
: well as it had been when it was newly brewed.
:
: It's behaving by all means like the original Agfa
: Rodinal. In terms of use, I can apply the same
: dilutions and time/temperature used for the 'real'
: Rodinal. The resulting "parodinal" (that's a cool
: term...can I use it? :-)) developed negatives look
: the same as Agfa Rodinal-developed negatives. My
: observations are based on three types of film only-
: Fuji Neopan 400, Kodak Tri-X and my standby generic
: Chinese panchromatic films. If there is any
: difference, it's not observable.
[X] mi lehet ez a kinai film amit a teszthez hasznalt? Lucky vagy nem?
: The real origin of the film remains unknown- the
: local spooler won't say. The film would sometimes
: have the characters 'zhong guo' marked on its edges.
: It never has frame numbers on it. Lucky film may
: have crisper grain, and that may be good- this film
: OTOH has mushy grain which tends to suppress image
: contours.
:
: Been scanning film more than copying them digitally
: since I got an Epson scanner.
:
:~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
:
: The local spooler won't say :D. I think its made
: by a factory based in Xiamen, based on what I saw
: from the 'pancake' container label. Its got a
: really mushy emulsion. Not so high silver weight,
: and has Svema-like tones. Contrast tends to be on
: the flat side. Overall its like an emulsion from
: the 1950s or even 1940s which works marvelously with
: the old optics.
:
: The examples shot with (inherently)soft J-3 got even
: softer with the low res emulsion.
:
: The little label says "Xiamen Fuda
: PhotoChemical...." That factory may be different
: from "Xiamen Photochemical Factory" which made
: "Xiamen" film. Xiamen Fuda may be the one who made
: the Generic BW film which I've used for the
: Paracetamol developer test. The backing paper looks
: similar to that found with Xiamen film. Are the
: spools metal or plastic? The spools I found with
: Xiamen, Era (at least those from before 1994) were
: made of metal.

:
: Not being asked this, the good man also told me that Paracetamol is

; Solution A
; Water, 125F/52C 625 ml
; p-Aminophenol Hydrochloride 100 g
; Potassium Metabisulfite 300 g
; Solution B
; Cold Water 200 ml
; Sodium Hydroxide 200 g
; Stock Solution
; Cold water to make 1L
:
: Mixing instructions: Add chemicals in specified
: sequence. Always use cold water when mixing sodium
: hydroxide due to risk of heat reaction. Unlike many
: other two part developers, you must mix both parts
: together to make the concentrated solution. In The
: Film Developing Cookbook, Troop and Anchell suggest
: the following sequence for making the concentrated
: developer: Allow Solution A to cool until a
: precipitate forms. Mix Solution A in an iced water
: bath at this stage, then very slowly mix in Solution
: B while constantly stirring until the solution
: suddenly turns dark. Follow this by adding the last
: drops of Solution B, again very slowly. Always wear
: gloves and protective goggles when mixing sodium
: hydroxide.
:
: Dilution: 1+25, 1+50, 1+75, 1+100 and others.
:
: Starting point development time: varies by dilution.
:
: Note 1: This is the old formula for Rodinal and is
: not identical to the commercial version; however,
: practical use is very similar and starting point
: development times remain the same.
:
: Note 2: Mixing this formula is recommended for
: experienced users only. If you would like to

: Paraminophenol (Rodinal) Film Developer
:
: A P-Aminophenol Hydrochloride film developer for that is economical and
: excellent for slower speed films (ISO 32-200). Unless graininess
is desired,
: this developer is not recommended for faster films. This
developer produces
: medium-grain negatives with good sharpness. The contrast is
variable and depends
: upon dilution and development times. The chemicals are used to
prepare a stock
: solution, which is diluted 1:50 or 1:100 to obtain the working
solution. One
: liter of stock solution yields 50 to 100 liters of working
solution. The shelf
: life of the stock solution is about 6 months. The working
solution is used once
: and then discarded.
:
: MIXING THE STOCK SOLUTION
:
: SOLUTION A Chemical Amount Units
: Water 625 ml
: P-Aminophenol Hydrochloride 50 g
: Sodium metabisulfite 150 g
:
: Boil the water and cool 5 minutes. Add a few crystals of
metabisulfite from the
: total called for. Then add the p-aminophenol hydrochloride and
the rest of the
: metabisulfite.
:
: SOLUTION B Chemical Amount Units
: Potassium hydroxide 215 g
: Cold water (68°F/20°C) to make 500 ml
:
: This solution must be prepared in a sink and in a well
ventilated area. Place a
: dry plastic mixing bowl in a sink and place the solid potassium
hydroxide in the
: bowl. Measure out 350 ml of cold water and carefully add the water to the
: container. Stir the mixture with a plastic spoon until the solid
has gone into
: solution. Stir gently and avoid splashing the solution. Add cold
water to make
: 500 ml of solution.
:
: When potassium hydroxide goes into solution, considerable heat
is generated. If
: your water was not cold enough, the solution may start to steam.
If this should
: occur, add some ice to cool the solution. DO NOT BREATH THE VAPOR. If the
: solution starts to steam and you cannot cool it, leave the room
and let it cool
: off by itself. After the solid has gone into solution, let the
solution sit
: until it reaches room temperature. Using a plastic funnel,
transfer the solid
: potassium hydroxide solution to its plastic storage container.
The transfer
: should be carried out in the sink. Add sufficient cold water to
make 100 ml
: using a portion of the water to rinse out the mixing bowl.
Before any of the
: mixing equipment leaves the sink, rinse and wash with cold water
until you are
: positive that no residual hydroxide remains. Be sure to wash the
outside of the
: storage container before you remove it from the sink. Should any of this
: solution be spilled on your skin, wash immediately with cold
water followed by
: soap and water.
:
: To the above solution A, slowly add about 180 ml of solution B
while stirring. A
: precipitate will form. As the B solution is added, the
precipitate will dissolve.
: The object is to add just enough Solution B to nearly, but not
quite, dissolve
: the precipitate. A few traces must be left. When this is done,
add cold water to
: make 1 liter of stock solution.
:
: USAGE
: This versatile developer can be used in varity of ways and
adapted to very slow,
: fine grain films or with the fast ISO 400 or 500 films.
:
: Slow Films: For low contrast subjects where you need to build
contrast dilute 1:75
: and develop 12 to 15 minutes. Dilute 1:100 and develop for
68°F/20°C the same
: time for normal contrast subjects. To soften, reduce the
68°F/20°C time in the 1:100
: dilution to 8 to 12 minutes.
:
: Fast Films: For increased contrast develop 12 to 15 minutes at
1:50. For reduced
: contrast develop 12 to 15 minutes at 1:100 68°F/20°C. For normal contrast
: develop about 12 minutes at 1:75 68°F/20°C.
:
: NOTES
: This is not a fine grain formula, although it will deliver extremely high
: acutance and can be either compensating or pictorial as needed.
With faster
: films the grain will be quite course. This can be avoided by
using 0% sodium
: sulfite solution to dilute the stock developer. The sulfite.
which acts as a
: silver solvent at this concentration, will reduce grain size
(and at the same
: time impair acutance, though a good balance can be struck.) A
typical developing
: time of 11 minutes at 1:75 (sulfite) at 68°F/20°C with Tri-X is
common, but it
: could easily be half that or higher than that, depending on individual
: circumstances. If your negatives are consistantly too contrasty,
reduce the
: development time or increase the dilution of the developer. If
your negatives
: are consistantly to soft, increase the devoloping time or reduce
the dilution.
: Many such controls are available with this formula, and may
result in negatives
: of exceptionally high quailty.

: Potassium Metabisulfite 300 g
:
: Solution B
: Cold Water 200 ml

:
: Mixing instructions: Add chemicals in specified sequence. Always use
: cold water when mixing sodium hydroxide due to risk of heat reaction.
: Unlike many other two part developers, you must mix both parts together
: to make the concentrated solution. In The Film Developing Cookbook,
: Troop and Anchell suggest the following sequence for making the
: concentrated developer: Allow Solution A to cool until a precipitate
: forms. Mix Solution A in an iced water bath at this stage, then very
: slowly mix in Solution B while constantly stirring until the solution
: suddenly turns dark. Follow this by adding the last drops of Solution B,
: again very slowly. Always wear gloves and protective goggles when mixing
: sodium hydroxide.
:
: Dilution: 1+25, 1+50, 1+75, 1+100 and others.
:
: Starting point development time: varies by dilution.
:
: Note 1: This is the old formula for Rodinal and is not identical to the
: commercial version; however, practical use is very similar and starting
: point development times remain the same.
:
: Note 2: Mixing this formula is recommended for experienced users only.
: If you would like to purchase a ready-made liquid version, we recommend
: Calbe R09 which is available from JandC Photo
