In this video today, I’m doing a rundown of the Jobo CPE2 (including developing a roll of Kodak Portra 160 to show you my workflow) and talking about why this tool has quickly become one of my favourites and made developing film at home way more enjoyable, efficient, and consistent. I’m also going to share the tanks and accessories that I use, including the 2509n sheet film holder which has been a game changer for me developing 4x5 film at home.

Damn you just changed my life yet again the first time was when you recommended the Horseman 45FA 5x4 camera. I used to use one of these Jobo CPE’s years ago but forgot about it and how effective they can be especially the lift version. I am actually quite happy shooting developing and then scanning/ printing 5x4 film at a selective pace so I use the STEARMAN PRESS SP-445 Compact 4x5 Film Processing System. For the quantity of film I shoot it’s perfect. I have very low out-put and at my age I won’t be working anywhere near what I used to in the 80’s or 1990’s those days have gone I’m lucky enough to be able to reencounter the time to practice my first love now my children have grown up and left home.

Love the 2509n for 5x4 and the Jobo Expert 3005 for 10x8. I never got the hang of putting two films on 2500 reels, though, even with the little red clips. Films would often overlap no matter how carefully I loaded them on the reel.

Great run down of the CPE2. I love my CPE-2 and CPE-3. I have gotten great results for B&W as well as Kodak Flexicolor C-41. One thing I do is use my TCS1000 to bring my water to a degree or two below your developing temperature. Then use that water to fill the Jobo. The CPE's have a 300 watt heater which is good for holding the temperature or eating the water a few degrees, but they struggle with heating up the water 10 to 15 degrees F. I also level the Jobo before filling completely.

They're also great for doing colour prints. I use mine for both E-6/C-41 developing and RA-4 with up to 16x12 inch paper which is a nice addition. As you mentioned it makes DD-X economically viable (and you can also use it more than once, they don't recommend it and yet give compensation % for multiple uses...) and also gives a nice repeatability. I found a cheap kitchen timer with some velcro sits perfectly in the space where a 4th knob would be next to the on/off one and makes things a lot easier than a phone with wet hands or gloves. I have to say though the temperature on mine is more of a vague idea than accurate, that thermometer is really necessary if you want one yourself. The lift is handy if you can find one but not by any means vital. Would say that it's probably the best film developing addition I've bought in a long time.
@mjmdiver1137 10 ай бұрын
Great video... There is a caution about the solution amount for people that are not familiar with these Jobo tanks (which I think are the best out there for developing, whether by hand or rotary). You have to be careful that you maintain the minimum amount of stock developer in the solution! This is different from the minimum amount of total solution in the tank (as you mention is mostly shown on the Jobo tanks). This means that people will need to look at the dilution charts for the developer you are using and figure out what the minimum amount of developer is (based on the dilution options for many of the developers) and then determine if you will have enough developer stock solution in the tank when using the minimum required for the Jobo tanks. If it doesn't meet the minimum stock amount, you either need to change the developer solution or increase the amount of working developer in the tank.

@@russellsprout2223 I understand the convenience of processing b/w film by the Jobo rotary processors, and great if the results you are getting work for you. However my comments were intended to be helpful as clearly rotary processors have there limitations. I have been processing film for over 40 years, and recently invested in the Film Developing Cookbook which is known as the bible for b/w film developing. Some interesting points “ Rotary processors are designed for colour developers, which are specifically designed to work when film is exposed to air during processing. The only black and white developers we can recommend for rotary processors are undiluted high-sulfite types like D76, Microphen and Xtol. It is a cornerstone of black and white developing technique that we avoid exposing film to air.” Regarding my point about acutance, quote “ Unfortunately continuous agitation interferes with the formation of sharpness-enhancing edge effects.” In other words films developed in the conventional way with controlled one minute agitation are going to produce sharper negatives. This may not be an issue if you only shoot large format. One final quote” Rotary processing is sub-optimal for all development processes where highly dilute or fragile developers are being used, and that applies to all tanning developers “ I hope this explains why I made my original comments and good luck with your processing.

I got a CPA2 (and an additional, nasty one as a donor for the lift kit) a few years ago after processing with a Patterson tank upgraded with a home-made rotation system (a cheap, slow electric motor, a CD, some screws, and some glue). The change in consistency between development methods, for me, was significant. But let me tell you: The CPE/CPA system is just a gateway drug to the ATL1000, which makes the process even nicer. If you get an ATL1000/1500, don't get rid of your CPE/CPA: They are still very useful when developing photographic paper.

When I got my cpe-3, the jobo thermometer that came with it was faulty and so the water bath and chemicals were 5-7 degrees Celsius too high and left blotchy marks all over my negatives. With film developing it’s frustrating as it can be a long process of elimination. After ruining 5 rolls of film, it turned out it was the thermometer so I purchased a $2 coffee/milk thermometer which works fine. The version 2 looks much better quality than my CPE-3. The CPE-3 has stickers on the dials, not markings. My sticker wasn’t out on straight so it’s hard to tell where 38 degrees actually is. There’s a place for the thermometer to clip into at the opposite end of the bath which then doesn’t give an accurate reading for where your chemicals are at the other end. For $3,000 AUD I was very disappointed. Surely you should be able to set the temperature accurately and it maintains it reliably like a sous vide. It also takes a long time to heat up unless you fill it with warm water to begin with. There is also no drain to let the water out on the CPE-3 so you need 2 people to carry somewhere to tip it out. It also says in the instructions (which are an A4 typed word document) that you can’t leave the water in there for longer than 8 hours. The reels are also more challenging to load than Patersons so I have found that cutting the film leaders into a rounded shape keeps the film edges from getting caught in the reels when loading. If there was something else to choose from out there I would get it in a heartbeat, but there’s not much else out there unfortunately. I must admit it does beat standing there doing inversions with a Patterson tank as you have a bit more freedom to walk around. However, if I’m only doing a couple of rolls, it’s much quicker with a small tub, sous vide and Patterson tank.

@@garethVanDagger My Jobo is hard plumbed in my dark room in the basement and has lift option, so it's pretty much always faster to use it, especially these days since I favor 1-shot black white and green developer that has longer development times. The only time I don't use it is when I want to do stand development with DDX 1 + 9. I got lucky on the Jobo a few years back from an estate sale situation so I hardly paid for it. Right out of the gate I didn't trust the temperature, so I just checked it on my test runs and opted to add the sous vide I already owned as a "fix". For what it is, I think the Jobo brand new price-wise is crazy and I can't believe there isn't a Chinese company making knock-offs yet.

Not sure what happened to my comment but will try again, can hugely recommend the Bellini C41 kit from NT Photoworks, a bit more labour intensive but seriously good. As regards developing tips, the Ilford Washing Method is a very economical way of washing your film at the end, saves on a lot of water, and with the Jobo it should use even less. I’d also use a setting agent like Kodak Photo Flo after the final wash too. This video has inspired me to get out and fix the CPE-2 I got really cheap a few years ago, it has a crack in the main tank.

Hi Kyle. The main difference between the CPE and CPP models is that you can purchase a lift that allows you to pour and empty chemistry out of the tanks without having to pull the tank off of the Jobo; and removing and replacing the lid. It basically increases time efficiency. Another difference is that the tanks can hold a larger quantity of film. Cheers!

Depends on the kit. The one I use I add on about 15s for each 4 rolls developed, just got to keep note!
@KyleMcDougall 10 ай бұрын
Still getting used to this kit, so I can't comment on how many rolls you get. I will say though, I dropped a leader I snipped off in month old developer and it did nothing (whereas it should have apparently turned black). So I personally wouldn't let the developer go for more than a couple of weeks.

Is there any negatives to having a constant agitation?
@RobP614 2 ай бұрын
How have you kept the Blix from building up pressure and exploding out of the Jobo developer???
@KyleMcDougall 2 ай бұрын
Hit or miss. What I've found helps is once I put in the blix, and then give it my three manual inversions before putting it on the Jobo, I open the lid to release some pressure.
@c.augustin 10 ай бұрын
I tried rotary development (but manually on a roller stand) for my 4x5 negative, using the 2520 tank - and always get some sorts of streaks and uneven development. I have used these additional flaps that are highly recommended by Jobo to get even development - well, does not work well at all. How do you develop your 4x5 negatives in the 2520 tank? Do you use the additional parts?
@KyleMcDougall 10 ай бұрын
Interesting to hear that. I’ve had no issues at all. Very even development. I’m using the supplied ‘flaps’ and always add a little extra volume. Around 300ml.
@c.augustin 10 ай бұрын
@@KyleMcDougall I'll give it a try with extra volume. One difference I've seen is speed of rotation - I was much more "gentle" (slower rotation), and this might be part of the problem. On the other hand I also have streaks when using the SP 8x10 tray for development, even when using the "panning for gold" movement (but I think I get closer to finding out what to do to avoid them). Very annoying.

how do you know how many dev cycles you can get from reusing the chemicals with the more effective use of chemicals?
@KyleMcDougall 10 ай бұрын
Cinestills instructions suggest adding I believe 2% (I’d have to double check) longer per roll of 35.

Does the constant rotation impact the amount of agitation you do for each development? Especially for BW processing?
@mynewcolour 10 ай бұрын
The rotation is all the agitation required. Typically times are 10-15% reduced I think (ilford data sheets will confirm that).
@KyleMcDougall 10 ай бұрын
Hey John, for colour dev times remain the same, and as mentioned, the rotation is the agitation. For B&W I reduce developing time by 15%.

for color film especially, don't you get faster chem exhaustion with smaller quantity of chem?

The chems are being put back in with the rest of the 1 litre mix.
@allys537 10 ай бұрын
@@KyleMcDougallthanks, but I ment that the chem in the bottle during development is less than a Patterson tank. When I develop, say a 120 roll I'm using almost 1000ml, where I get the "full force" of that amount of chemicals. Does the lesser amount during development, exhaust faster? I know it gets replenished when you mix it back in to the unused rest of your 1000ml... Sorry I hope that makes sense.

At the current price, it would take 333 rolls to pay for itself. I am not sure it is worth the price. On the other hand, so easy to develop color film now.. The last time I developed color film was when I was a kid and it seemed like it was a 10 chemical nightmare. So easy now.

You gotta get the lift. It’s what really pushes the Jobo over all the other rotary options and allows you to be very consistent with times.
@garethVanDagger 10 ай бұрын
To me the lift is a pain as it’s one more thing to wash out before putting on another batch, and I forgot one time and some blix got into my pre-wash. The only thing it saves is my walking to the sink to tip out the pre-wash.
@seanc5718 10 ай бұрын
@@garethVanDagger I’ve never washed my lift once and have never had issues. I just do a few water rinses at the end that are part of my normal process and that water is enough to keep the lift clean. I’m probably my 300+ rolls deep on this thing and run control strips every few batches and have never seen carryover from the lift mess up the next batch.

@@seanc5718 oh I see, so you do your rinses whilst still on the machine? I’ve been taking my drum off and taking it to the sink for the rinse which leaves blobs of blix in the pouring spout part. Your method will mitigate the contamination issues. How do you monitor the temperature? What thermometer do you use? I had a faulty jobo one and ruined a bunch of film so I’m scared now in relation to what thermometer is best

@@garethVanDagger yeah I do a few water rinses on the jobo and then remove the tank and do the rest of the rinsing off the machine.

I strongly suggest using professional grade chemistry in your Jobo instead of home kits with blix. In my opinion, it is a waste of money to invest in good gear, such as Jobo, and use inferior chemistry in it.
