This is fantastic. I will try this.
Parabéns ao Wagner e Rogério! Belíssimo trabalho de resgate. Esse material poderia ser transformado em material didático para divulgação entre os nossos estudantes. Provavelmente existem talentos que precisam ser despertados.
That's fantastic. I have bulk 46mm film and I am trying to figure out how to make a machine, a tool really, to help spool 127. This at least helps me visualize what I am trying to do. Thanks.
Where do you get the Paracetamol Powder. I’m having a difficult time finding it in the USA. Any suppliers ?
Hello, I bought 500g over here in Brazil, a couple of years ago. But now sales are forbidden unless you are a chemist or someone in the pharmaceutical business. I still have some, but I know that sooner or later I will have to resort to the pain killer.
Incredible video! I used the auto translate to watch it and it was really helpful! Greetings from germany.
i'll try this and see if it will also work on my kodak 3A pocket folding camera
FELICITACIONES! Espectacular el video!! Impresionantes los resultados!!! GRACIAS POR COMPARTIR!!!!!!!!!!
Thanks very much. Very useful.
easily the best diy bellows I've seen, wish I'd seen this before figuratively bashing my head against the wall for over a week trying to make a 3 layer bellows for a 6x9 camera lol. This was about 6 years ago, but I'll keep it in mind when I inevitably become the owner of another camera with shut bellows. On a different note: I got a Super Ikonta 531/2 today. It's generally in great condition, bellows included thankfully, and I'm looking for information on how to _maintain_ them. What I found was rather iffy in my opinion, mostly because it didn't take into consideration the material the bellows are made of/adhesive and so on. First of all, the outer surface of these bellows is leather, right? it's got a tiny bit of mold (very very little). How would you advise I clean them and maintain them going forward? thanks a lot in advance!
Yes it is leather, at least, Zeiss Ikon advertised that theirs was real leather. This mold is called bloom and it is due to oils and waxes that solidify on the surface. You can wipe off what is loose with a soft brush. The remaining, when it occurs in leather goods in general, can be removed with a solution of equal parts of water and vinegar. But the bellows is so delicate, it is not like a shoe or belt, so I would go extremely careful with that. Avoid by all mean letting the solution to penetrate in the inner layers. Use a cotton swab barely humidified in the solution and try working without actually wetting the bellows. There are commercial products to perform the same job, that could be also a option. Later you can apply a leather conditioner. Good luck!!
Grato por compartilhar Lungov!! vou tentar fazer em minha câmera!!!
Salve grupo. Uma pergunta: Há interruptores e fixadores "baratos" tipo o Rodinal?
Oi Rodrigo, o interruptor mais barato é usar água. Muita gente usa, mas aí eu aconselho passar uns 2 ou 3 banhos para lavar bem o revelador da gelatina. Coisa rápida, enche o tanque agita uns 10 segundos e enche novamente, três vezes. Ou então ácido cítrico. Eu faço uns flaconetes de 5ml de ácido cítrico a 50% e uso um a cada revelação. Mas só água funciona bem também. Usavam muito ácido no auge da fotografia analógica por conta de produtividade, para ser mais rápido. O fixador pode ser só 250g de Tiosulfato de Sódio e 25g de Metabissulfito de Potássio para fazer um litro de fixador. Muito fácil de comprar os dois. É o fixador clássico. Dá para muitos filmes.
Obg@@wagnerlungov1825 fixador se dilui?
@@icerodrigo Não, ele é usado puro. Mas depois de usar você guarda e usa novamente. A parte do filme ou papel que não recebeu luz ainda tem emulsão e esta precisa ser removida ou irá escurecer e manchar. Tem que ficar só a prata que foi reveladas e ficou preta para fazer a imagem. A que não foi revelada precisa ir embora. É o fixador que a dissolve e por isso pode ser usado várias vezes até ficar saturado de prata. Eu dou as instruções mais detalhadas de como preparar e usar nesse post aqui: apenasimagens.com/pt/formulas-laboratorio-fotografico-preto-e-branco/
Nice video and good tips. Here is a suggestion, though: Using potassium hydroxide instead of sodium hydroxide saves you the trouble of having to deal with crystals forming. Everything dissolves properly. Rodinal contains exactly 0.5 mol/liter of p-Aminophenol (your formula contains 0.4 mol/liter). So to make 250 ml of developer, the correct parodinal formula uses 18.9 g paracetamol, 49.8 g sodium sulphite and 22.4 g potassium hydroxide. The difference will be small in use, but it is a lot easier if you do not have to filter anything, and you can use the published Rodinal development times and dilutions more accurately.
Thanks Jaco, I will try your recommendation in my next batch.
Deepest thanks to both of you. Your combined expertise will be the first I will try. Cheers
Just tried it. Worked very well. Film is drying now. Soon to scan. Thanks again.
Excelente vídeo! Ajudou muito um estudante no começo de suas aventuras no analógico
Excellent presentation. Thank you.
Great video, thank you so much. I always wanted to make one of those, but with flash and a condenser. You may enjoy this story - - I used to work a large tricolour copy camera that one would operate from within, the intent of which was to reproduce large colour copy work directly to a Fuji photo paper, processed using Cibachrome chemistry, one generation…there was a room, probably 20 x 30 feet, attached to another at 20 x 6 feet. They were separated by a wall with a lens turret and a filter wheel. The large room had copy lights, a vertical vacuum board on a focus rail and the exposure controller. The other had a front-faced mirror to reverse the image and direct it to a horizontal vacuum board, and the shutter release. There were a number of gorgeous, massive Schneider lenses. The filter wheel had three round gates, two of which were occupied by narrowband filters (blue and red, if memory serves) with one blank for white light exposure. Colour balance AND print density were simultaneously controlled by duration of the exposure through each of the three gates. There was logarithmic math you could do to figure it all out, if so inclined. Totally bizarre camera/enlarger. Loved it. Thanks for reminding me of it.
The instant I saw you were incorporating a Linhoff in this project, I knew you were my kind of nerd! Well done sir, bravo!
Very Good indeed, my congratulations.
Parabéns, para foi muito bom todas as suas informações, muito obrigado.
Thank you for your *really* excellent work. I hope more people see this video, AND your great website!
Perfeito.
I wish I was smart enough to made this. Amazing!
Very nice project. Why the multiple flashes?
Multiple flashes are useful to make test strips in order to find the right exposure time. It is also a good thing when doing dodging and burning.
Very nice project and considerate.
So this has to be done with a type of paper that is different from the darkroom paper? A uv paper? I enjoy your videos, thank you.
I use it whenever I want a contact print. That includes regular photographic paper in regular darkroom. For instance: my Durst Laborator 1000 can handle negatives up to 4x5" in size, but I shoot also 13x18 cm and 18x24cm, in those cases, I place the contact printer under the enlarger light, which is in focus but without any negative, and print it. Prints made by contact are beautiful and even in smaller sizes they worth a try. In former times most of the box cameras images where printed by contact. Thank you for your comment.
E realmente funciona. Inclusive com um Dmax intenso m.
I acquired a small box of these as 5x7 size- now I understand what they are and how to use them! Thank you sooo much for explaining! Keep making videos please
I was just referred to this video by the new Facebook group Photo Film Slitters. I had the idea to use an old 120 camera and wanted to see if others had already worked out how to do it. Damn helpful video, thank you for sharing your experience! I can see using this to cut film for other sizes as well.
Ficou top parabéns
que trabalheira vc gravar dois vídeos… um em cada língua. parabéns!
Realmente incrível.
congratulations for your work. I've an L1000, nice enlarger. you gave me strenght to start usung it again after 20 years
Obrigada, Wagner Despertou reflexão 😊
I'm looking into paracetamol pills and it looks like they have different kind of starches and stearic acid in them. Any advices on time and procedure?
Many Paracetamol pills come with some add-ons, like vitamin C or caffeine, aimed to improve an influenza condition. For a developer it is better to stay far from those and look for the ones having only paracetamol and the inevitable starchers. Normally it is all written on the package.
@@wagnerlungov1825 I appreciate you wanting to help...
What an amazing creation and a generous heart to share all of your work and knowledge!
I mixed this Rodinal and used it all up developing 3378 as negative and on PF2 as prints. Worked great. My videos show the results. I just made a new batch, May 23, 2023
g'Day Wagner,just discovered you! What great project. I've got most of the parts laying about so I'll build one, Thanks. I think I will adapted for a heater.
I've been doing this a few years now. Still learning, but getting more consistent. But this is an excellent overview, thanks for making it. I had the same problem with Steve Lloyd's (Chroma) plate holders; they're nice, but require thin glass. I have been able to get some 1.5mm glass that works OK, but the 2mm (probably slightly larger) I cut from single weight window glass don't fit at all. Very frustrating to be so close. On the good side, the thin stuff fits, and I persuaded him to make 4x10 plate holders, which I've enjoyed using as a result.
With regard to the very interesting aluminum coating plate, I wasn't sure how it was heated or cooled, but I will note that at the Eastman House, they had a coating plate from one of the labs (perhaps Kodak) that was an aluminum plate that had pipes running beneath the surface, allow you to pump cold or warm water through it. Keep it warm for coating, then run cold water through the pipe and it would cause the plates on top to set up immediately. I always wanted to try to rig something like that for myself. In the meanwhile, I simply lay the plates down on a slab of granite countertop offcut I picked up out of the trash somewhere that stays cool enough to help the plates set up quickly. I do the hand pouring method you mentioned, which mostly works well enough for me, although it's a bit messy occasionally. I found it helped me to do it over a tray of water so I'd stop worrying about it; staying calmer helped a lot. If you want to dig deeper into this subject (including more modern emulsion making), getting a copy of Ron Mowrey's book on emulsion making may prove interesting to you. Note that some of the recipes from older books (such as Baker; less sure about Eder) expect the use of "active" gelatin, which is not what we get these days. Throws off the percentages somewhat.
@@RobertBrazile Hi Robert, the aluminum coating table has 6 Peltier (Google it and you will what it is) elements beneath the cold stage. That is an electronic component, 60x60x4 mm, with two wires. When electric current flows across it one side transfers heat to the other in a very high ratio. So one side gets very quickly cold and the other very hot. If current keeps flowing the Peltier will burn out within minutes. To avoid that one has to provide means to remove that thermal energy from the hot side and supply some heat on the cold one. The aluminum plate intended to get cold supplies heat that it gets from the hot gelatin supposed to be over it (that is the aim of the whole thing). On the Peltier's hot side, 6 efficient heat sinkers remove heat as two fans force an air flow across their flaps. There are two tunnels running and connecting both aluminum plates. That hot air passes beneath the second aluminum plate and makes it moderately hot, just enough to easy the task of coating. That is the basic principle behind it. What I have on top of that is a micro processor Arduino with surface thermometers that switches it on an off when the cold plate reaches 20º or so, that is to avoid a burnout. In my first project I had a switch to invert the electrical current flow and reverse the hot/cold Peltier's surfaces (a somehow funny feature it has). But it took a few minutes to bring the aluminum plate from 36 to 23ºC, so I decided to split the table into two sections, one always warm and the other always cool. Hope this has given you an idea about how it works. In case you are interested I can send you pictures and more details about it.
Parabéns! Obrigada por compartilhar 😀
Isso tudo requer uma câmara que escura?
Sim, é preciso fazer o processo em um local com escuridão total, sempre que o filme estiver sendo manuseado. Depois que fez o rolinho, aí pode acender a luz.
Thank you so much for this video, I have Durst 3S Color, with condenser lenses, although I have them only for 13x18cm negative size. The system you showed here, would be great solution for me.
happy to have found this was researching 'intrepid's 4x5 compact enlarger and discovered their 'LED' source isn't up to the task in regards to making use of their Ilford based contrast filter system.
Thank you for sharing knowledge like this, great idea
