Ja fa uns mesos que volia provar algun sistema de revelat invers "casolà" per a pel·licula en blanc i negre. M'explico: el revelat invers (reversal en anglès) és aquell que aconsegueix positius directes a la pel·licula. S'anomena així perque tota pel·licula primer cal revelar-la com a negatiu, i dins del propi revelat, posteriorment es capgira el que es negatiu per positiu, tant en color com en blanc i negre. El revelat invers en color és el anomenat E6 i l'he fet alguna vegada sense problemes, amb "kits" comercials.
Per al revelat invers en blanc i negre també hi ha "kits" comercials, però amb l'afegit que alguns dels liquids, en especial el "bleach" o blanquejador son especialment toxics i perillosos. Però molt, eh (permanganat potassic i sobretot dicromat potassic, a sobre barrejats amb acid sulfuric).
Per això he estat experimentant amb diversos procesos "reversal" alternatius amb quimics menys angoixants (també s'han de tractar amb cura, però el mateix es pot dir de tota la resta de química fotogràfica). He provat variacions del més comentat, basat en disolucions de peroxid d'hidrogen (aigua oxigenada) a 40º, però els resultats foren decebedors, de pobres a nuls. En el cas que em mig funcionà, la pel·licula quedà plena de taques i marques.
Finalment vaig provar un altre procés basat en un doble bany blanquejador: clorur ferric primer, i amoniac després. I funciona!!! Amb bons resultats a la primera i tot a temperatura ambient de 20º!
En primer lloc faig servir un revelador normal de blanc i negre, però força potent, en aquest cas HC110 però en dilució A, la més concentrada, i durant 8 minuts. Després d'un bany d'aigua, ve la sol·lució de clorur ferric 1+1 (reaprofitable), un altre bany d'aclarit, el amoniac 4+1 (força concentrat), un seguent bany d'aclarit, i finalment una solució de metabisulfit de sodi de 30 gr. x litre (i de nou aclarit amb aigua).
En aquest punt, cal fer una cosa que tot el sentit del fotograf analogic li diu que no, i és obrir el tanc de revelat i exposar la pel·licula directament a la llum d'una bombeta incandescent una bona estona, ben be un minut. Fins i tot millor treure la pel·licula de l'espiral per a exposar-la be. El blanquejador ha dissolt les parts ja revelades, pel que ara només queden les sals de plata no exposades amb la càmera. Es veu clarament que està bé si s'aprecien les imatges ja en positiu però força palides. A mi em varen quedar més aviat grogues perquè no vaig fer un bany prou intents després del clorur ferric, que ho tenyeix tot de groc (però amb més rentat queden més blanques). A partir d'aqui es pot fer la resta del procés amb llum. Només resta tornar a revelar la pel·licula amb revelador normal i corrent, rentar i finalment fixar-ho com sempre.
La intenció final de revelar invers no és tant obtenir diapositives en blanc i negre, sino pel·licules de 8mm i 16mm que pugui projectar en pantalla com es feia abans. I vaig pel bon camí!

=====================================
I've been wanting to try some "homemade" reverse developing process for black and white film for a few months now. Let me explain: the reverse development is one that achieves direct positives in the film. It is called so because every film must first be developed as a negative, and later in the process itself, what is negative is chemically reversed for positive, both in color and in black and white. The reverse color proces is called E6 and I have done it once without problems, with commercial kits.
There are also commercial kits for black and white reverse development, but with the addition that some of the liquids, especially the bleach, are particularly toxic and dangerous. And I mean a lot (potassium permanganate and especially potassium dichromate, mixed with sulfuric).
So I've been experimenting with various alternative reversal processes with less distressing chemicals (they also need to be handled with care, but the same can be said for all other photographic chemistry). I have tried variations of the most discussed, based on hot solutions of hydrogen peroxide (oxygenated water) at 40º C, but the results were disappointing, from poor to nil. In the case that half worked for me, the film was full of spots and marks.
Finally I tried another process based on a double bleach bath: ferric chloride first, then ammonia. And it works!!! With good results the first time and all at an ambient temperature of 20º C!
First I use a normal black and white developer, but quite powerful, in this case HC110 but in dilution A, the most concentrated, and for 8 minutes. After a stop bath, comes the ferric chloride solution 1+1 (reusable), a long rinse bath, ammonia solution 4+1 (highly concentrated and also reusable), another long rinse bath, and finally a solution of sodium metabisulphite of 30 gr. x liter of water (and again rinsed with water).
At this point, you have to do something that all the analog photographer's sense tells you not to do, and that is to open the developer tank and expose the film directly to the light of an incandescent bulb for a long time, well a minute . Even better to remove the film from the spiral to expose it well. The bleach has dissolved the parts already revealed, so now only the silver salts not exposed to the camera remain. It is clearly seen that it is good if you appreciate the images already in positive but quite pale. They were rather yellow for me because I didn't take a bath enough times after the ferric chloride, which dyes everything yellow (but with more washing they become whiter). From here you can do the rest of the process with light. All that remains is to develop the film again with normal developer, stop bath and finally fix and wash it as usual.
The ultimate intention of reverse developing is not so much to get black and white slides, but 8mm and 16mm film that you can project on the screen as it was done before. And I'm on the right track!
Here is the video that helped me learn this process, thanks to Analog Resurgence (which explains it in detail):

The Film Photography Project now brings you D96 B/W negative developer. Long used in the motion picture industry as the standard B/W developer, but previously only available in very large quantities. We now have it available in powder to make 1 US Gallon.
D96 is a lower contrast film developer with the ability to increase the contrast by increasing your developing times or agitation. We have tested this developer with not only cinema films like X2 (Eastman Double-X), ORWO Cinema Films and FPP LOW ISO BW, but with standard B/W films like Kodak Tri-X. T-Max and Ilford FP4 an HP5 films.

Homemade coffee based film developer.
My formula:
Dissolve 5tbs instant coffee in 6oz water.
Dissolve 4tbs washing soda in 2oz of water. Stir until uniform.
Add soda solution to coffee.
Dissolve 1000mg Vitamin C in 2oz water. Dissolves fast.
Add Vitamin C solution to coffee/washing soda mixture.
Put in freezer until temp lowers to 20C.
I developed for 15 minutes, agitating 15 seconds for every minute of development.
This scene was a test of how well Provia could capture a scene with a LOT of dynamic range. Metering puts this scene at 7 stops, from the darkest ceiling at 10 seconds to the bright trees out the window at 1/20. It's confirmed - slide film is good for about 5 stops, maybe 4 1/2 :) The trees are obviously blown. The edge of the window (at 1/3 second) held good detail. If the day was overcast and I got down to 4 stops of range, this would have turned out a bit better - if still a boring shot :)

Die Fujifilm X-E2. 100 Profitipps
Valley & Zuidas area Amsterdam, the Netherlands
The dramatic, geology-inspired, plant-covered Valley stands out in Amsterdam’s Zuidas neighbourhood with its three towers of 67, 81, and 100 metres and its spectacular cantilevered apartments. Named the best new skyscraper in the world in the 2021 Emporis Skyscraper Awards, the building distinguishes itself in several ways: firstly, it combines offices, shops, catering, cultural facilities, and apartments in one building; secondly, unlike the closed-off buildings elsewhere in the Zuidas, the green valley that winds between the towers on the fourth and fifth floors is accessible to everyone via two external stone staircases.
Designed by MVRDV Architects for developer Edge, Valley is an attempt to bring a green and human dimension back to the inhospitable office environment of Amsterdam Zuidas. It is a building with multiple faces; on the outer edges of the building is a shell of smooth mirrored glass, which fits the context of the business district. Inside this shell, the building has a completely different, more inviting natural appearance, as if the glass block has crumbled away to reveal craggy rock faces inside replete with natural stone and greenery.
Various locations throughout the three-tower complex offer breathtaking views of the city – the apartments, of course, but especially the sky bar at the top of the tallest tower, which visitors can access via the Molteni flagship store on the ground floor. The building’s layout is tailored to a mixture of residents, workers, and visitors: on top of the three-storey underground car park, offices occupy the lower seven floors, with apartments located on the eighth floor and up. Much of the building is open to the public: from the publicly accessible footpath that zigzags up to the central valley from the street level, to the Grotto, an atrium that forms a covered street on the first floor where the Sapiens Lab – a breeding ground for young scientists – will soon open. The grotto is connected to the outside by two large skylights that double as shallow water pools in the valley level above, and its natural stone flooring, walls, and ceilings – the same stone used on the surfaces of the valley and towers – makes clear that all the public areas of the building are part of the same apparently geological formation.
The design and construction of Valley is utterly bespoke, requiring the sustained commitment of hundreds of designers, engineers, builders, consultants, and of course the client. The enormously complex shape required a special commitment to fine detailing that further enhances the design concept. MVRDV’s technology experts created a series of custom digital tools to perfect the building, from a tool that ensured every apartment had adequate light and views, to a programme that made possible the apparently random pattern of over 40,000 stone tiles of varying sizes that adorn the building’s façades. Each of the 200 apartments has a unique floor plan, made possible by the interior designs by Heyligers Architects. And the outlandish cantilevers of the towers are possible thanks to innovative engineering, including eleven steel “specials” bolted to the concrete building that take the overall appearance to the next level.
Landscape architect Piet Oudolf developed a matrix to select the right plants for each location in the building, taking into account factors such as wind, sunlight, temperature, and maintenance. Trees, for example, are largely found on the lower floors, while the uppermost levels mainly support small plants. In total, more than 271 young trees and shrubs and approximately 13,500 smaller plants occupy the natural stone planters, representing 220 different plant species. In the coming years, the building will mature into the lush appearance of the design team’s vision as the greenery continues to grow. The biodiversity of this landscape is further supported by bird- and bat boxes as well as various bee and insect hotels. Maintained using an automatic irrigation system and by “façade gardeners”, the trees and plants on the terraces will positively affect the well-being of people living and working in Valley.
Valley combines insights in the field of sustainability, technology, and health. The building’s energy performance is 30% better than local regulations require, it has received BREEAM-NL Excellent certification for the commercial spaces, and the residential area scored an 8 out of 10 on the GPR Building Scale, a Dutch measurement tool that scores buildings across five themes of energy, environment, health, quality of use, and future value. The latest smart technologies are integrated in the office spaces, including IP-based Building Automation Systems and various sensors linked to monitoring actual usage.
The construction of Valley took four years, with the first residents and entrepreneurs moving into the building at the end of 2021, opening fully in September 2022.

Testing my developer against Coffer's positive developer. Trying to determine the cause of my unevenness. Results here were rather inconclusive but it seemed to me my own mix with extra alcohol was too streaky. Plus the developer was harder to wash off.
I ended up modifying Coffer's formula by cutting the Ferrous Sulfate by 20% and increasing the alcohol in his by 20%. Perfect plates the next day.
