Colour Chemicals

morrisphotos123 · Sep 20, 2012

I was wondering if anyone could list all the names of all the chemicals i need to devolope Coulour Films and a chart to show devolopeing times for a film called Boots ISO 200 COLOUR FILM 24 EXP

Thank you

You can buy ready made/mixed chemicals from a variety of sources in UK. Just have a look on the web. I suggest AG Photographic, Fotospeed, or Firstcall Photographic. These people will supply a kit which contains developer and the bleach fix for a number of films.

The standard development time for C41 colour negative film at 38 degrees C is 3mins 15 seconds. As far as I know all colour film developers are the same time for the same film. Temperature is fairly critical and any deviation from the 38c will not give you optimum quality. If the Film you are talking about is not C41 type, but C22 then you will have to look further

the film says Proces CN-16/C-41

You are OK then with the film. Ask the dealer about a kit by Tetenal. However, if you are only intent on processing this one film then a kit is a very expensive way of doing it.

Unlike Black and white, C-41 film is processed at the same time and temperature, regardless of manufacturer or ISO. A 1 liter kit will develop anywhere from 8 rolls (what the box says) to double that or even more (what others have tried). I usually play it safe and only develop 10. Once you mix the chemicals, you will need to use them up. It's a use-or-lose. So I'd encourage you to not start developing until you have more than the one roll... try to at least have the 8. Have fun!

it does not state what order to use the chemicals in as the kit i ordered has 6

Did you happen to notice the sticky in this forum? (there was a url link here which no longer exists) It has a lot of useful info in it.

I don't mean to imply that getting all the right chemicals is easy, because it's not, but in case you ever want to use Flexicolor chemistry from Kodak or similar from Trebla, it'll probably be worth your while to read it.

I'm not clear what kit you are using, but in general, you use the developer first, then bleach, then fix, then stabilize. In many kits, the bleach and fix are combined into one solution.

So normally you have either 3 or 4 solutions for C-41 process. If you have 6 chemicals (and assuming your kit is really for C-41 processing and not E-6), then you probably have two or three developer solutions that have to be mixed together before use.

What kit do you have? If it didn't come with directions, then I would suggest you contact the merchant and ask them for it.

EDIT: I noticed your link above. You are using the Tetenal C-41 1 liter kit. That is a very popular kit with a lot of people. I haven't used it, but it definitely should have come with an instruction sheet, or else the instructions would be on the box. Someone here on the forum should be able to give you the details, if you don't have them.

morrisphotos123 · Sep 21, 2012

the kit is called [h=1]Tetenal C41 Kit 1L[/h]

R.Gould · Sep 21, 2012

All the Tetenal chemistry I have used over many years have vome with very clear instructions, the best way forward if you realy want to try colour developing with this kit is to sit down and read the instructions carefully and follow them to the letter, that way you should get a result

That is $20 USA a kit, not including shipping. For about 15 rolls, it costs about $1.50/roll. It seems fair.

At my local Costco, it costs about the same amount to process a 35mm roll. 45 minutes wait time.

Hi Thank you for everyone's help I have 1 more question I have got the Tetenal C41 Kit 1L I was wondering if anyone could help me on mixing up the correct amount up to fit in my Film Canister. The film canister I have holds for 1 35MM film 290 ml
I have attached The Instructions. also where do I find a chart on developeing times for colour Films
Thank you

R.Gould · Sep 25, 2012

Can't help with the colour chemistry,but I would advice that you use 300ml instead of the 290, that extra 10 ml can make life a lot easier, and it alwaus better to have a little bit more in the tank as film reels can slid up a tad, and you can the top of the film bot developed enough, also, as I understand it, all colour films in c41 have a standard developing time, so you don't need charts as you do for black and white film

morrisphotos123 · Sep 25, 2012

what would you say is a standard developing time

MartinP · Sep 25, 2012

The answers are on the instruction sheet which you have attached above.

R.Gould · Sep 25, 2012

As Above, read the instructions and all your questions will be revealed

MattKing · Sep 25, 2012

As others have posted, your instruction sheet does have the answers to your question, but just in case the form of notation isn't clear to you ...

Times noted in the standard form {6' 00"} mean 6 minutes and 0 seconds - in other words the ' symbol is used for minutes, and the " symbol is used for seconds.

Hello I have been developeing B+W films with great succsess. I bought a Tetenal Colortec C-41 Kit. I tried using it but onceI I had finished the last step and have come to scan the negs I have noticed they look very blue or had a slight yellow colour. is there any way i can try and fix it or is there something i need to do nextime I try another film Thank you

kevs · Sep 27, 2012

Hi Morris,

First, check that your scanner is calibrated properly. A poorly adjusted scanner and screen can skew results considerably. Find an image with a white object and adjust scanner controls accordingly, and use a testcard to check your screen. Secondly, if the images with the very blue and slightly yellow casts are on the same film, it's probably not the chemicals; the cast would be consistent over the whole film unless you did something really weird. If that doesn't help, check your workflow and make corrections.

If you can post a scan, somebody might be able to diagnose the problem more accurately. Unlike B+W, colour developing needs accurate temperature and time control - it takes a little practice to get things right. And any cross-contamination of the dev with bleach-fix will cause problems (but not vice-versa).

Have fun,
kevs
