hi guys I know this is a weird way to start an episode but better be bear with me for a second so yesterday we went to Brighton with friend hi guys hi it was it was France birthday I wanted to celebrate and go to bright joy because we know none of us have ever been there so I went there and I thank my patrons I was able to get a Senate which is a camera it was the Olympics edition a black TTL camera are really nice and I wanted to try that in Brighton to make it like a special thing and shoot in color and I was shooting some ultra max 400 color film and I was like yeah let’s go there and try it it’s gonna be so much fun Branagh so we shoot the whole episode we had a great day with some K anyway we when it was time for me to rewind the camera I had no idea how to do it so I decided to wait come home and today search on the internet and see like if I if I was right or know how to rewind the camera then I did what I’m supposed to do and I realize that yesterday while I was shooting at one point I was like winding the film and then like it feels stuck and then I was able to keep whining and yeah I broke the film and I had no idea when I arrived today and I started winding the film I can’t wind it anymore because the film is stuck at the camera so I put the camera on my changing bag and and as you can see I was able to I mean this is the canister this is where the film goes and the film is out there’s nothing here the film is currently inside this camera so I’m facing this problem I can’t send this to develop because the fit was of the camera so I need to take a film out of here and a little bit and the problem is I have never ever developed color so I have no idea how to do that so we’re debating now if I should search online and buy the chemicals and develop at home or try to see a way of sending it to I don’t know living place and they can take the film out I don’t know we’re going to sort it out I hope you can follow us around this time and we’ll show you what happens all right so these came in the mail let’s see what it has inside that’s a lot of plastic bottles so in case you’re wondering how is this work here are the instructions and on the instructions you will see that there are actually different parts of each and every chemical these are three step chemical developments so we’re going to need to create the color developer the bleach and the fixer and then the stabilizer so in order to create the color developer we need to add water and one two and three parts I’m going to make the solution of one later because these balls are one liter bottles so this is what I’m going to do let’s see so color developer part one or two or three instead of three chemicals to create the color developer and then yeah the bleaching the fixer our part one part two and finally a stabilizer is only one part that’s it I’ll have to follow the instructions that are here so LM trying to film a video my love doesn’t look that hard I guess the most the hardest thing is to maintain the the temperature on the water and then the temperature on all the fixers and stuff but let’s see how I’ll see how it goes right so the water is ready I’m gonna right there so you see it’s running and it needs to be between 20 and 45 degrees Celsius so we are add 30 a 2.5 so that’s okay according to my cookbook 400 millimeters so as you can see here is a measure on 400 islets that’s about 400 now this is 200 millimeters of this so let’s it’s gonna get 200 millimeters oh it’s closed and 200 millimeters of the second power for this oh it’s turning then you see that it’s crazy last are 200 millimeters of this guy I mean it’s not it’s not pink anymore chemistry man now for the pigs we need 600 millimeters yes 600 200 millimeters of this up man this thing looks oh it’s hard to see the numbers now it’s super dark look like movie blood two hundred million years of this guy we have a bleak sway and last but not least we need 800 millimeters of water – how – Vinny metres of stabilizer alright K so I’m going to try to start a developing and I’m actually kind of scared because seeing this it says that I’m going to try the 30 degrees in development 30 degree Celsius and it says that I can be off by 0.5 degrees and oh man I’m such a mess I’m super bad be like having like consistent consistent temperatures but I’m really really bad at that so I mean I mean I got a try that’s the only way I can know so I’m going to try to develop something and let’s see let’s see how it goes all right so here’s the funny thing I have a camera in here what I’m going to do is I’m gonna grab this developing tank I’m gonna put it inside the changing bag and I’m going to pull the film inside the tank and then I’ll develop it oh boy I’m pretty sure this is gonna be fun man I was hard all right so the chemical sneak to the end of exactly 30 degrees all right I can pretty slow on my film with water in steady at 30 degrees for five minutes let’s go five minutes these are 30 degrees exactly and I feel so good are doing this like every time I see people on YouTube doing this I always have like nice stuff and I’m just using like kitchen appliances and stuff damn am well we’re in the 6 minute mark so let’s just wait and see all right let’s check this baby out 33 degrees so it’s 6 minutes let’s go now we need to rinse this and for that we’re going to use water I am already because it needs to be between 30 and 40 degrees so we are the 6 minute mark last one one minute I made it okay not it worked I’ll hang it and see how it goes that’s the whole experience man um it was it was MIT it was kind of stressful when I start doing it I was super worried about the temperatures and whatnot and there is reason to be worried like everybody already feeding the monster of the temperatures but at the same time everybody was feeding the monsters of the temperatures one of the first time I was developing in black and white so I don’t know how true or not the temperature Monster is regarding the color development but I did my best and I think I think it works out fine I haven’t actually scanned the results yet but just from the experience of developing it’s it’s good enough for me for now like I feel accomplished just doing that though I realized I really need some kind of heating system because I really hate just you have water running I don’t like wasting water I feel like terrible when I do that so what I’m going to do is I am going to try some kind of way of heating the water like they sell some fish tanks water system for people who have like fishes and they want to keep like under constant temperature I’m going to search online and find one that’s okay and cancer my purpose I’m going to try that because I’m really I don’t know it feels like good I feel really good about trying developing film color so I know besides it’s much cheaper than just send it for development which was the reason why I start developing black and white in the first place but now that I can develop color man there’s a whole range of things that I want to try now like a bunch of film I want to see if there’s any difference when I develop it on home or not besides that can give me a lot more control than just sending to develop I mean it’s more automatic that way and it might be safer in some cases but my last time I Center for development results were not that good and I don’t know if I should blame the lab or the film or myself so in this area at least I will know that the development is going to be consistent all the time if there’s a mistake it’s going to be on my end so I’m going to be held accountable for all the things that happen I’m happy that I tried it if you haven’t tried it I hope this video can motivate you to give it a try it’s fun it’s it’s just like developing black and white but it’s more precise as you already saw so if you’re like me and you’ve been developing black and white for quite some time maybe you could give it a try to the c41 it’s not as terrible as I thought it would be it’s quite fun actually so I don’t know you’re going to try you might be you might be hooked and it might be cheaper than just send it for developing and scanning so I hope you enjoy this episode and I’ll see you next week guys keep shooting before Ling Ling can we have like one second so I can show you exactly what’s going on here look look at this

100 thoughts on “How to develop color film: Tetenal Colortec C-41

  1. Next step is E6 then I guess. But take note, the kit goes bad within two weeks once mixed because the first developer only lasts that long. So just make sure you have 8 to 10 rolls of slide film shot and ready to develop. Although technically, you will make your money back for the kit after only developing two rolls.

  2. There is a 3 step process for color that is similar to BW processing that may be quicker. I haven't tried it yet but have ordered the kit and waiting to shoot some color film.

  3. Don't worry, Tetenal is pretty much bullet proof. I just pre-rinse film with water that feels warm, not hot, keep the chemicals roughly at the 38 degrees C, developing time between 3:15 and 3:45…with agitation, without..turned out good every time 🙂

  4. Ayer justo revelé mi primer carrete de color y ha sido una sorpresa ver hoy este video 🙂 Se monta un poco de cisco por el tubo ese del acuario de peces (que por cierto, funciona muy bien), y yo al menos usé guantes, mascarilla y gafas xD ¡A seguir revelando!

  5. Siempre pensé que era al único al que le sucedía eso con los rollos en una Zenit, de hecho por esa razón aprendí revelar 😀 gracias por el video, que por cierto me motiva a probar el C-41 Thanks Ed

  6. Good job. Now I should restart my B&W developing again. But color, wow. Its the same fear I have. (i.e., temperatures)

    Next I want to see if you'll do real print making using an enlarger and paper!


  7. you could always put the film in a black cannister, the type that the film comes in. Not the cassette that goes in the camera, but what it is transported in. has to be fully black, ie the type that most ilford comes in. Then send ito be developed.

  8. did you put the color developer and blix and stuff back in the containers or just dump it out? can you reuse any chemicals?

  9. Hey man…amazing channel. Found it yesterday and just can´t stop to watch it:) Thanks for the Brighton shoot. I love the town. Lived there about three years and miss it now. These pictures turned out really great with that vintage look. Might not be what the kodak suppose to be, but for me looks fantastic…definitely not a wash out look. Thanks for the inspiration, now I can see, that it is not that hard to develop colour film. Btw. as someone mention you should try to find helios for the Zenit, I got it from a flee market for just about fifty pence with non working zenit body and still use it on micro 4/3 body. Cheers Jan

  10. Hey Ed, I've also done C-41 a few times and ran into the same issues as you. I also need to mix 3 chemicals + a very small amount of a fourth chemical to make the developer – so small I need syringes to measures it. Bleach and fixer are separate. The results are nice, I love colour film but the process is so tedious I still have 6 rolls of film that wait to be developed since April.

  11. Mr Paves. I am from Chile. I bought a Canon ae1 program, I have been taking plenty of pictures. Do you know any C-41 and B&W dealer ? I need to get the quemicals to develop my pictures by my self. I want to learn the process.

  12. There is a method to develop color film called "the stand development" where you don't need to worry about the temperature of the chemicals. Here is a blog with instructions.

  13. ive been into photography on and off within the past few years, this year ive gotten really into it, especially film photography, i love your videos 🙂

  14. Thanks for sharing your experience developing color film Ed! I still haven't gotten around to doing it myself but perhaps I'll try it someday.

  15. Buenas Ed, me pregunto dónde conseguiste las botellas vacías selladas. Te vienen con el pack de Tetenal? Me voy a España de vacaciones y creo que voy a disparar mucho carrete de color… Igual me animo con esto del C41. Mil gracias y a seguir así, no sólo inspiras si no que a la vez enseñas. Good man!

  16. Yeah, I like too the colour, but I don't scan. I enlarge all my negatives, but colour papers are almost unavailable in this time.

  17. thx man. I bought the same kit for a month now, did not had time, all so i was a bit scared to do it. Your video saved me. I used the 38 degrees and it worked. Thumbs up dude!

  18. I use a plastic ikea storage container, fill it with hot water, let the chemicals sit in the water, stick the thermometer into the developer bottle and wait until it reaches 39C. take all 3 bottles out and start. there's no way the temperature will drop more than the 2C tolerance during the whole development process (I've timed it 🙂 ) .

    I also found a great app called 'lab timer' which allows you to set up all your timers with labels so it's less things to think about. I found the first time I developed I was thinking about all the stuff I had to do and mildly panicking so anything that can help to remove some of these things is great. The 3 most important things I've found to help in no particular order are 1) fast reading thermometer 2) funnel (getting the chemicals back in the bottles is quick and easy) 3)lab timer app

    I've had actually more issues with scanning than developing. Getting rid of those microscopic hairs on the frame holder is a right pain.

    Love your channel

  19. Really glad you liked Brighton Eduardo! It's a shame I didn't bump into you, I would have liked to say hi and thank you for the videos 🙂

  20. Thanks to your video I jumped into the C-41 process and can now develop my pushed color film. It changes everything to be so independent.

  21. I'm really glad you took up through your first time, sometimes when people have been doing something for a while they get so used to do it they forget to mention little things. I've just ordered my first C-41 kit and my first film is Fujifilm Pro 160ns from my Bronica, so I'll be doing my first 120 film and colour film on the same day. 😳😳😳😳😳🤢🤢🤢

  22. Had you find the fish tank or thing that holds the temperature? if you found one, please suggest me !

  23. they have these things used for sous verde. u place in a tank of water and heats the water to a specific temp and maintains that.

  24. Shipping thta stuff to the USA is very expensive, and I am having a hard time finding the color film developer kit in the USA. :/
    Maybe I can find an alternate brand with reasonable shipping prices. Thanks for the video!

  25. Hi! I'm a big fan of yours trying to set into the magic world of developing my own film (more for cheapness that for the artistic side). happens that I have a few colored rolls that I'd like to develop as B&W, do you think this is possible? if so….any ideas where to find a timing chart? I've tried yesterday but the results haven't been great…Thanks so much 🙂 you'll find me at @samscomparin on the Twitter 🙂

  26. I don't know how you did it, but theoretical you should have rotate the film inside the tank in order to use that kit… Well, good for you!

  27. Developed my first colour film with Tetenal C-41 3 bath blix and totally messed up the temps and dilution it ranged between 36 and 41 Celsius I forgot to empty my pre-soak before putting in the developer so I guestimated and added an extra 1.30 to the development time to compensate I never inverted the tank I just used the twizzly thing I forgot to cool the blix which was at 41 Celsius I then rinsed with the same 41 degree tank water a few times. I think the stabiliser was the only thing I got right also I didn't bother to squeegee. Anyway the results, absolutely perfect negatives 100% better than what I got from the local 1 hour process lab with the same film type and camera those were grainy as hell and streaks everywhere. The film superia xtra 400 cheapo stuff turned out to be more forgiving than any B&W I've developed maybe the film itself is forgiving I don't know. That's about as brute as it gets and negs still came out spot on with nice colours barely perceptible grain and nice contrast. It's taught me I don't need to stress about temperatures and timings as much as some people like to think with that film anyway.

  28. but wait….HOW THE HELL DID YOU PULL OUT THE FILM? I JUST RIPPED MY FILM WHILE TRYING TO REWINDING IT! I seriously need some help and Jesus! 😀 
    I'm about to lose my mind !!!
    Great video btw!

  29. After the stabilizer can I squeegee the film? I've noticed that water spots are leaving marks on the film. Is that permanent?

  30. Hey, where did you get the developing tank and the cloth with the arm holes for the process from the film roll into tank? thanks so much!

  31. Fish tank heaters aint all that cop man. Search out a "Sous Vide" man they are supposed to work within a tolerance of 0.1oC.
    I got mine on order right now with my first Tetenal kit.
    Been using Kodak Flexcolor which is nice and gives that classic retro looking 1970's style filum look. Which is nice with cheaper films like Fujicolor C200 but with something like Ektar or Portra I wanna see come real colours pop out!

  32. Hey Eduardo! Thanks for being a massive inspiration to me to get into film.. Just wondering what Agitation method did you use in this video?

  33. If you are a bit lazy try a "sous vide" to heat and keep your chemiclas at the right temperature. It's also great for cooking!

  34. can you add a link to all the equipment you used; like the chemicals to the plastic bottles that you poured the chemicals into.

  35. Genial el episodio!! Tengo una duda, jamas revele nada pero quiero comenzar a hacerlo ya que aquí en argentina sale realmente caro muy caro! El químico que sobre (so es que sobra) se lo puede reutilizar para otro revelado? Gracias!!

  36. I thought that only Poles do not read the instructions.
    And I never broke off the film in Zenit TTL.

  37. Hey man i wanna ask…..
    Have you tried getting more rolls than the stated 20 per litre?
    I read that you can get upto 40 rolls with a bit of maths…



    Now we've got a simple algebraic way to figure out the dev times for your Unicolor C-41 kit. It may not be perfect, but it seems to work. It may even err on the side of overdevelopment, which is the better way to go with C-41 if you're not sure. More about that later.

    The math reduces to a simple equation:

    t = 140 / (40-n), where "n" is the nth roll that you're going to be developing. If you're doing two rolls at once, just develop them both as "n", and it's close enough.

    t is the developing time you use in place of the recommended 3.5 minutes. The temperature should be 102 degrees F.

    Failing to extend the dev times could explain why some people get blue images. When you under-develop or under-expose C-41, the shadows (especially) become blue. I've noticed that many times. I think it might be that the yellow dye layer (you know, the top one) gets more development relative to the other two layers, which take longer for molecules to diffuse into them. When you color-invert yellow, you get blue. So, if your pictures have too much blue in them and the shadows are too grainy (and blue), it could be from not extending the dev times to compensate for depletion. This would be similar to running the chems at too low a temperature.

  38. There was a 'professional' from a camera store, where I bought my film scanner, saying that you can't develop color film by hand.
    That you needed a '2000$ machine for development or it would be impossible'.
    And he was so arrogant and sure of it, I laughed from the inside.
    And I was like: 'bruh, look at Eduardo and thousands of photographers who actually
    do it by hand. And the results are superb… Are you nuts??

    Thanks for the video, Eduardo!

  39. If you want a really good water heater/circulator then get yourself a 'Anova Culinary Sous Vide Precision Cooker' from Amazon. Just clip to the side of a 10Ltr tank, pour in your water and set the temp. Drop your chemicals in and wait for the temps to stabilise and your ready to go.
    Saves messing about with 2 or 3 fish tank heaters, and this thing is accurate to 1/10th of a degree.
    You can cook a nice steak with it when you've finished as well. Love mine, but the price is a bit of a hit at £99

  40. Zenit was the worst camera I ever had. It was one of my first and it only helped me to appreciate how good other cameras were in comparison.

  41. Hi, there are a few C41 kits out there: Unicolour, Tetenal, Cinestill etc. What the differences? Could you do a review and comparison please? I can't find any information anywhere on the internet on the differences

  42. High Eduardo I see you used a 2.5l kit and wanted to know if you make up only 1 litre, how long does the remaining 1.5 litres last for?

  43. Great video. I develop B&W and have been put off doing colour because temperature and thought I'd need something like a Jobo which your video shows I don't.
