Reveladores a granel
El mundo está lleno de reveladores. En serio. Si alguna vez pensaste que más allá de tu botella de HC-110 o Rodinal sólo existía el salvaje D-76… estabas en un gran error.
Pero no sientas apuro: no es un error grave. De hecho, y según cómo se mire, no conviene hacerse la pregunta de «con qué más podrías revelar tu negativo» porque la respuesta puede ser el inicio de una tortuosa, larga y a menudo infructuosa búsqueda casi sin fin que te va a llevar a descubrir una verdad peligrosa para la consecución de resultados predecibles: el mundo está lleno de reveladores.
La historia nos suele contar que en un primer momento todos hemos confiado en los reveladores comerciales: HC-110, Rodinal, D-76, Xtol o Tmax developer, por citar los quizás más nombrados. Luego hemos pensado que algún revelador de autor, como los de Gago o los de Moersch, los de Barry Thornton o de Willi Beutler, podría dar un toque único y distinto a nuestras fotografías, algo que permitiera diferenciarnos de los demás. Siempre curiosos, aún hemos ido un paso más allá y hemos buscado fórmulas de reveladores antiguos, medio olvidados, nos hemos sentido casi alquimistas y nos hemos convencido que detrás de las fenomenales imágenes de Edward Weston o de William Mortensen el revelador ha jugado un papel insustituible y definitivo.
En mi opinión, buscar un revelador que se ajuste a nuestra manera de entender las imágenes es algo bueno para nuestro crecimiento como artesanos o como artistas. Buscar, encontrar y trabajar y comprender ese revelador ayudará a que nuestras fotografías puedan tener un sello especial que las diferencie de muchas otras fotografías.
Pero no os ceguéis pensando que el revelador va a compensar un fallo vuestro a la hora de exponer, no. El revelador puede jugar muy bien su limitado papel, pero la magia la crea el fotógrafo mezclando en el matraz que es el negativo los factores que determinan un buen cliché, y si la relación entre estos factores no está equilibrada el peor de ellos determinará la calidad final.
Para terminar —y por si finalmente no me hacéis caso y decidís probar—, os dejo el trabajo de Paul Fitzerald al recopilar unas pocas fórmulas de reveladores hoy en desuso. Este trabajo puede asimilar un caserón decrépito y abandonado, lleno de muebles de olor denso, poca y turbia luz, sonido seco y telas blancas y polvorientas de misteriosas formas. Pero los fantasmas de este caserón están muy vivos…

“Films to be developed in this solution should be given twice the exposure usually given when alkali-containing developers are to be used. This developer keeps well.”
“This formula has been found to give excellent results with all makes of film. Grainless enlargements up to 20 diameters are consistently obtained from negatives developed in it and in the hands of a skilled photographer, good enlargements up to 50 diameters are possible.”

Kodak Developer DK-20
((This appears to be THE choice for Plus-X and SuperXX, as universal as D-76 with finer grain. Lowering the borax amount in DeFero’s formula would extend the development time

Replenish at a rate of 3/4oz per roll developed (80 Sq. In.).
“De Fero has reported that in the Kodak DK-20 formula, the substitution of the Kodalk by 1/3 of it’s weight of borax greatly improves the fine grain and keeping properties of the solution.”
“If a two-bath formula for divided development is desired, the solution is made up as above but omitting the borax. The film is treated 4 min. in this bath, then, without intermediate washing, it is held 4 – 6 min. in a solution of 5 grams of borax in 1,000cc of water. Divided development of this kind has the advantage that the developer does not become exhausted nearly as rapidly as the single solution types, assuming that the alkaline second bath is renewed frequently.”

“Mixing directions:
Use a 1 gallon narrow mouthed bottle for mixing the developer. First check the volume of the bottle and mark it to indicate the exact level of 1 gallon of solution. Fill the bottle half full of water at about 90°F and dissolve the chemicals in the order given. After adding each chemical, place the stopper in the bottle so that only a small quantity of air is present during agitation. When all the chemicals have been dissolved, add cold water until the solution comes up to the 1 gallon mark. Insert the stopper tightly to exclude as much air as possible. Allow the developer to stand about 2 hours after mixing. Cool to 68°F before use. If only a portion of the contents of the bottle is used at one time, it is suggested that the balance be saved by filling a bottle of smaller size which should then be stopped tightly.”
