pouring with the machine turning will stop or severly slow the spillage. Also, tilt the hose up, hold it straight up when you pour in, you won't get any spillage. Also, if you add a small aquarium pump on the far end, you will get more consistent temperature. Now, one might argue that a brand new machine should not have to need modifications, but it does.
This is a good video! I'm glad that Jobo are getting people to make videos about the machine. When I first tried to figure out how a Jobo actually worked a while ago, it took me so long to try and actually figure out how it worked and how it did everything. Most videos assumed you knew a lot about it already. Good stuff!
Awesome videos! Your content is awesome, the videos are well shot and edited, and your reviews are spot on! Just wanted to pitch in and say that I have an older jobo that heats the chemistry the same way. I wasn't super happy with the uneven heating either so I bought an inexpensive aquarium water pump to circulate the water. It has made a pretty decent difference in water temperature consistency.
Hey Ed, I just wanted to say that I love your videos and you're a great inspiration for film photography personally. Thank you for your videos and for your lovely art which is photography
EduardoPavezGoye you know Eduardo for this product it was appropriate and necessary to speak at length because it's an obscure item. When I review camera lenses on my channel for example I try to be thorough as well because folks deserve that. Your vids are legit. Oh there are a few of your vids I was dying to see but since Im not proficient in Spanish I couldn't benefit from like the camera reviews especially the Mamiya. I was like aaargh! Lol I understand it's your home language bro so no disrespect of course. I took Spanish in high school but didn't apply myself. Peace my man
Thanks Eduardo for the video! I think there is one thing you did not mention and it makes me wonder if I'm not mistaken there ... isn't one of the main advantages that it's using very little chemical compared to a standard inversion tank? Thanks!
Muchisimas gracias por tus videos. Me has motivado ha adentrarme en este mundo tan intersante de la fotografia de rollo. Asi se dice? Bueno, film photography. Cada cual hace videos de la mejor manera que sienta y tu manera me resulta super turbo intetesante. Gracias por inspirarnos.
Great video. Same problem you have with Jobo reels, I have now with Paterson. I've started with Paterson, but after adopting to Jobo, I'm completely furious when I need to load Paterson reels, it just takes forever. It is probably to what you get used to, I found Jobe tanks/reels, far more easier to use. Even though Jobo reels feels very fragile.
Thanks Ed... Just be yourself. That's what we all tune in for.... Awesome machine but super pricey... Cheers. Say Hi to Fran. Must remember to check in on her channel too.. It's been a while..
Someday I'd like one of these, I develop a lot of film in my sink too and it's such a pain doing C41. The counter gets covered in bottles and water gets everywhere
I hand develop slide film in the kitchen where the sink heats up my e6 chemicals. Worth knowing about me: I a ton of slide film in my freezer so based on your conclusion I would win on getting a jobo! Regarding touching e6 chemicals, I have yet to get harmed by it and I don't use gloves! Would I enjoy using a Jobo, sure but I don't have 1000+ euros for a new kit and I enjoy developing by hand. Keep up the good work!
Rotary film processors are the cause of most printing filtration problems the outside section of film gets more agitation than the centre and because c41 is a time / temperature/ agitation process the film will have uneven density and colour temperature along its length .daylight handline such as the nova or deep tanks is the only way .
@@edpavez LOL that’s true. I kept thinking about using different funnels but yes, you’re right. Do you think rinsing between chemicals might be ok? Or does it screw up the developing process? In case it wasn’t obvious I’m a noob at this 👈
@@peoplewithpixels when developing E6 you need to rinse your film in between, so that rinses the hose. but again, there are processes (C-41) where you pour one chemical after another in the same tank and there is some cross contamination, but not enough to ruin anything. no need to worry.
Hey bro, the jobo! I have a duolab and I'm not fully sure how to use it properly. The lowest temp it can rise up to is 24deg but my film needs to be 20deg. Any idea How? I try to develop 1 bnw roll every week. It would definitely be easier but will take away the 'fun in inversing or agitating.
I'm agree with you. I think a dream machine for a color printer. You can work without put the hands in the water and dry them every time before to go at the enlarger. It is very tedious. About the reel I'm not agree. I love them. Plastic is better and the film run into it very easy. Prices are too high on eBay now. It will rest a dream for me.
Nice review, but why didn't you take us step by step thru an actual film development process? With 11:53 spent on this review, that should have been easy. I wanted to see this machine developing film.
Hola Eduardo. Saludos de España. Me preguntaba si sabrías algún laboratorio (en Europa) que esté especializado en revelar ECN-2, o al menos lo revelen "normalmente" o con cierta regularidad. Tengo como 10 rollos por revelar y prefiero enviarlo a un sitio que estén familiarizados con este proceso. Gracias de antemano. Un saludo y enhorabuena por estos vídeos, nos ayudan mucho.
EduardoPavezGoye Muchas gracias por contestar! Seguiré buscando. Un saludo. PD: Hace poco compre la revista de los chicos de "carrete" donde te hacen una entrevista, me gustó mucho. 🤘
At the price they sell it I wouldn't buy...probably make sense for boutique lab . 1500 € for the lift version is way too expensive. It is a cool tool but is basically plastic with warming resistance and a rotating motor. Everything in their website is hell expensive. if they lower the price I could start thinking about a xmas present :) . BTW, great video as always Eduardo.
I'm not sure he ever answered his initial question, which was why you would spend $1,750 or more for a tempering tank and a drum roller, plus the mechanical pouring mechanism. Much is made of the convenience, but the Jobo unit requires as much attention and otherwise, and you end up cleaning up more containers and parts. All of the Jobo bits each cost far more than necessary, and as a whole, these units have a pretty poor track record re repairs. Jobo literally went out of business a few years ago, and is now back trying to make it in a even smaller market, so will you be able to find those repair parts when it goes bust? $1,750. can be used for a lot of better items for your camera or darkroom.
Jobo is not out of business. They lauched the CPE-3 machine not long ago, and there’s a store in Berlin with all the parts. It is expensive, yes, and I would never buy a brand new unit of these. For developing black and white or C-41, I wouldn’t buy it, but if you want to develop E6 in 4x5 or 8x10 in several sheets at a time, there are not many options for you. It’s either this or a much more expensive machine. It’s not for everyone, and I had to sell mine when I left the UK... but man, developing eight rolls of 120 at a time was amazing. I miss it.
Eduardo, me encanta la idea de volver a revelar película pero sí me pesa el impacto ambiental que tiene especialmente en este momento. El gasto y contaminación de agua es lo único que me pesa personalmente en revelar. Qué opinas al respecto?
Hi Eduardo. Great video as always ;-) It's a bit sad that the JOBO CPA(pronounciation like Yo-Bo - The company name comes from the founder JOhannes BOckemuehl) ist the only processor still produced (beside the hand crafted Filmomat that is rarely available). Taking the small number of pieces sold into consideration I personally think it is still a bit overpriced but has the possibility to develop film as well as paper and is not limited to a certain number of steps (aka chemicals) within one process. Still I would prefer the Filmetta (also sold as DURST Color Lab) because it is really full-automatic and I don't do paper right now. If you don't know the Filmetta, there is a short video about it on my channel (sorry, can't post the link for spammy reasons). Though it's german language I think that's not so much of a problem for you as multi linguist ;-) BTW: How did you get in contact with Tetenal? I've been mailing them for months with some questions but never got any response :-(
Hey! Thanks for the tip. I have never seen a Durst Filmetta. Thanks for letting me know about your video. I'm always happy to practice my German. :) Regarding the guys at Tetenal, I was contacted by them. I'm pretty bad at self promoting, to be honest. Sorry that I'm not being too helpful!
rotary film processors are ok for monochrome film but are a disaster for c41 which is a time / temperature/ agitation sensitive emulsion. The film on the outside of the spool gets considerably more agitation than the inner part so that there is a progressive density change from one end of the film to the other. This is ok with mono, as compensation at the printing stage is easy enough but with colour film the colour temperature is also changed.This can make printing a roll of film shot at a wedding with the groom in a grey (the hardest colour to achieve in printing)suit a chalenge. c41 should only be processed by inversion or in deep tanks the spool should never be rotated horizontaly .
Dear Harry - thanks for commenting on the processor movie. The agitation and film processing in rotation is actually one that renders one of the most consistent results. The more demanding the job or customer, the more we recommend the use of the 2500' tank system (black reels). Here the film layers are further apart - allowing for even more equal film processing of the whole roll of film. BTW: The larger the format - the greater the challenge to achieve even processing. the more even any film area is - the more easily will undulations be seen. This is one of the main reasons why many famous Large Format Photographers use the CPP-3 with the Expert Tank. (like Hiroshi SUGIMOTO). JOBO achieves the most consistent results. Please also note that many of the film production companies (such as KODAK, ILFORD,...) use JOBO processors in the process of their Quality Control. The industry is using JOBO processors for the consistency of processing results - otherwise impossible to achieve for small production lots. I hope this little reply is helpful. We wish you continuous fun with REAL photography: from grain to grain ;-) JOBO
Hey guys... Has anyone tried building a JOBO-like processing station for C41 color film development? If you havent seen one, google "jobo pcc2" So its basically a plastic tank filled with water that is being heated with some kind of an electrical water heater+ thermostate and Its used to heat both the film tank and the chemicals stored in bottles and submerged in the same heated water. It also has an elecromotor that slowly spins the film tank so that it develops evenly and so on... Using this you have 2 constant values in the developing equation...constant spinning and constant temperature. So you only need to keep your mind in mixing chemistry good. The problem is that this piece of mid last century equipment costs around $1500 up to $2000 on ebay...I think thats crazy... So I fugured... STEAK COOKER! :D They sell these slow steak cookers (or "sous vide" cookers for like $50 on ebay and its basically a precise 800W water heater that you pin to the rim of the pot and it keeps a constant water temperature and it even has like a small motor that corculates the water around so that it heats evenly to the temperature that you set. What I wanted to try is to put together the cooker on the rim of a large plastic tank, a small electromotor that would spin the film tank in water and some sort of a plastic frame that would keep the bottles with chemicals submerged. I thought that in order not to get electrocuted to death, it would be wise to fix the electromotor on the wall next to the tank, and spin the film tank via some sort of a transmission...like a rubber band or smth. And the film tank...I would hot glue the bottom of the tank to a large magnet so that it would be easy to pull it out from the transmission to pour the chemicals in and out of the tank. What do you think? Is there something that I'm missing? Has anyone tried something similar?
Do not use a rotary drum with c41, linear variation along the length of film will give unavoidable printing problems .deep tank or inversion daylight tank is the only way . To prove it ,process an unexposed roll of c41 in a jobo then using an analyser measure the density and color temperature of the control strip alongside the film sprocket holes . You will find a progressive change along its length . A nightmare if your printing a wedding with a grey suit in it .people with rotary film tanks think colour printing is difficult ,its not if you start with a film thats developed correctly .
Eduardo, ¿para cuando tus vídeos es español?. Es una pena que para un TH-camr latino que tenemos tengamos que verlo en Yankee. Por cierto, para evitar que el agua se caliente más en una zona que en otra, puedes instalar un pequeña bomba de acuario con un tubo que tome el agua del extra contrario y la expulse junto a la resistencia. Así se crea una corriente y hace circular el agua haciendo que se caliente de forma uniforme.
Mis videos no van a estar en español porque hace años que vivo en países de habla inglesa. Todos mis amigos y conocidos hablan inglés, y toda la gente con que me relaciono. ¿Te imaginas a todos tus amigos decirles "tengo un canal de youtube, pero no vas a entender nada porque está en español aunque ya no vivo allá, pero el contenido es interesante..."? No, no funciona. De todos modos, la enorme mayoría de mis videos tiene subtítulos :) claro, salvo los últimos que he subido porque como estoy cursando un doctorado, no me da el tiempo de coordinar una sesión de fotos, revelar, escanear, editar, subir el video y encima hacer los subs.
@@edpavez te comprendo perfectamente. Pues nada, seguiremos disfrutando de tus videos en inglés. Que a mi también me viene bien para ir practicando :-) Gracias, un abrazo desde España.
i know it may be convenient if you develop loads of loads of films or do it professionally, but first we get rid of all the digital electronic stuff by using film, and then there are huges machines to develope in single film tanks. i dont get the point of this, developing takes 10 minutes in a plaetic tank, why would you add a huge machine like that?
horizontal rotation produces uneven agitation along the length of film a disaster for c41 if your going to print a wedding with a grey suit in it . deep tank or inversion agitation is the only sure way to get uniform colour temperature . believe me
Not true. I've developed literally dozens of c-41 films over the years using a CPE2 and the later CPE2+ and have *never* experienced any issues with uneven development or density.
If you have a business, buy it, but 3000 dollars for such an imperfect product? Seems like a lot of money that could spent buying more film and more chemicals to have fun with
It's rediculous to sell a plastic tank, a boyler heater with a mechanical (!) thermostat and a wiper motor (yes that's all this is + the lift) in 2020 and especially at a price of ~EUR1700?! It's the same design as like 30 years ago... Joke.
pouring with the machine turning will stop or severly slow the spillage. Also, tilt the hose up, hold it straight up when you pour in, you won't get any spillage.
Also, if you add a small aquarium pump on the far end, you will get more consistent temperature. Now, one might argue that a brand new machine should not have to need modifications, but it does.

@@edpavez te comprendo perfectamente. Pues nada, seguiremos disfrutando de tus videos en inglés. Que a mi también me viene bien para ir practicando :-)
Gracias, un abrazo desde España.
Haha 'HIT THAT SUBSCR...' :D. You're cool by just being you, you dont need that.
i know it may be convenient if you develop loads of loads of films or do it professionally, but first we get rid of all the digital electronic stuff by using film, and then there are huges machines to develope in single film tanks.
i dont get the point of this, developing takes 10 minutes in a plaetic tank, why would you add a huge machine like that?
horizontal rotation produces uneven agitation along the length of film a disaster for c41 if your going to print a wedding with a grey suit in it . deep tank or inversion agitation is the only sure way to get uniform colour temperature . believe me
Not true. I've developed literally dozens of c-41 films over the years using a CPE2 and the later CPE2+ and have *never* experienced any issues with uneven development or density.
Am not gonna say first!
you mean chemicals
I'm already subscribed to your channel. So try and stop me now mister super cool TH-camr!
I solved the heating issue with a cheap fish tank pump to circulate the water. Simples
If you have a business, buy it, but 3000 dollars for such an imperfect product? Seems like a lot of money that could spent buying more film and more chemicals to have fun with

Are you serious?
here's my current setup, super cheap: th-cam.com/video/FSdhemzQ-q4/w-d-xo.html&
Mr. Ken thats for the higher end CPP-3. This is the CPE-3 that runs ~1700 on B&H
🤘🏾
It's rediculous to sell a plastic tank, a boyler heater with a mechanical (!) thermostat and a wiper motor (yes that's all this is + the lift) in 2020 and especially at a price of ~EUR1700?! It's the same design as like 30 years ago... Joke.
How the F is this a review? :))
