How To: Home Develop C41 Negatives

  Yes, its another post about developing.  Im in a very darkroom frame of mind at the minute as im currently in the middle of getting an enlarger setup in my spare room (going to look and probably buy tomorrow, yay).  Im thinking back to when i first started getting setup developing my own film and how i got lots of help from various forums but it still took me a long time to get all the information in required and to find a process that works for me.  So i thought that i would use my blog to pass on some knowledge to others, as well as my usual phototrip posts.

  So - this post is about my C41 process.  Unlike most others i started off doing C41 processing before i did black and white.  Most people start on black and white as its done (generally) at room temperature and there is more rom for error (yes, i know hardcore b&w enthusiasts will disagree, but lets just keep going).  However, many that get used to black and white seem to be under the impression that C41 is very complex and near impossible to do at home - but that just isnt the case.

  There are a few ways to do it.  Poeple get good results just getting a tub full of water and heating it up and if you fancy that route (lets face it, its cheaper) then go for it.  Personally i use a rotary processer - a Jobo CPE-2 to be precise.

  These are readily available on Ebay and all they are is a water bath with temperature control and a rotary motor which agitates your tank for you.  Some better (i.e. more expensive) models also have a lift which let you add and remove chemicals to the film tank without having to lift it off the rotary.  I find though that the CPE-2 easily meets my needs.

  As for chemicals i am a huge fan of the Rollei Digibase C41 kits.  I tend to buy from AG Photographic who are based in the UK as i have always had excellent servcie from them and they tend to be a little cheaper than everywhere else.  These kits come in a variety of sizes but i tend to go for the 1L kit which lets me do 4 batches of 250ml - around 20 films altogether.  These kits also have a long shelf life (when unmixed) which i find very handy as i often have a month or 2 where i dont have any films to process.  The only drawback is that the instructions that come with these kits arent the best.  There are washes missing and personally i think some of the times are off for processing which is why it took me so long to get my procedure nailed.

  So, what is my procedure?  Well, the Jobo tank i use allows for 1 x 120 film (or 2 x 35mm) to be processed (well, technically 2 x 120 films can go onto one reel but i dont like to do that).  I prefer to do my films one at a time simply for quality control - if something goes wrong during developing then i havent ruined multiple films.  I fill my Jobo with water (preferably warm as it means that you dont waste time and electricity heating cold water) and leave it to heat up to around 38C (C41 should be processed at 37.8 +/-5C).  I like to leave it to heat up for about an hour to make sure the temperature has stabilised.  Whilst the water bath is heating up i mix my chemicals following the instrucitons included with the kit.  The instructions say that they solutions must be mixed with water at 49C, and i am fortunate in that i can hit that temperature with the hot water from my taps.  If you cant then boil a kettle, pour the water into a jug and wait for it to cool down to around 49C.  The kit comes with multiple syringes - you need to make sure that you use one for fixer, one for stabiliser, one for bleach etc.  Use permanent marker to label them otherwise you will end up cross contaminating your chemicals.  Unfortunately there arent enough syringes included in the kit for 1 per chemical so i use the same syringe for parts A,B and C of the developer.  Some people may be renounce this but it works ok for me so i do it.

  So, you have measured out your chemicals and mixed them with water.  Pour them into their bottles, stir them well and put them into your water bath.  Whilst you wait for your chemicals to settle to 37.8C load your film onto your reels (if you dont know how to do this or even what im on about check youtube, theres lots of videos there that will help you out).  You're all set now and ready to develop (once your chemicals have heated up).  After about an hour dip a thermometer into your developer and check the temperature is stable at around 38C.  You will also need some jugs of water at around 38C too for washing yourn film later.  I like to fill a jug with a anrrow bottom and stand it in the spare space in my Jobo bath so the temperature keeps up.

  Once you're all heated up put your developing tank onto the rotary and set it going at full speed for 5 minutes.  This brings the tank and film up to a similar temperature to your chemicals which will stop your film being 'shocked' when you suddenly pour in some hot fluids.  Some people like to prewash their film.  They heat up the tank and then fill it with water for 3 minutes or so.  I used to do it but have personally gotten far better results by not doing so so i am dropping this step from my developing procedure.  If you google it you'll see a tremendous amount of debate covering this topic with everyone having a differing opinion about what effects prewashing/soaking has on the film.  If you do choose to prewash dont be worried when the water comes out a vivid colour like purple or green, this is the the anti-halation layer and dye being washed off your film.

  After 5 minutes it is time to start pouring in your chemicals.  Start your stopwatch and pour in your developer.  Put the lid on the tank and rotate the tank by hand 3 times so as to get coverage of the developer over the film, give the tank a solid tap on the floor/work surface to disoldge any air bubbles (remember this - it will make your film easier to scan later) then put the tank onto the rotary.

  My developing procedure is as follows:

Preheat 5:00
Developer 3:15
Bleach 6:30
Wash 1 3:00 (6 washes of 30s)
Fixer 6:30
Wash 2 6:00 (6 washes of 1m)
Stabiliser 1:30 (to be done at room temperature)
Dry

  With each step allow 7 seconds or so to pour out the first chemical and pour in the next eg pour the developer out at 3:08 and pour the bleach in at 3:15.  The washes are important steps but they are not included on the Rollei instructions.  The first wash should come after the bleach and consist of 6 changes of water every 30 seconds.  This makes sure that the tank is fully removed of bleach before you pour in your fixer.  The second wash comes after fixing and consists of 6 changes of water every 1 minute.  Again, this stops the stabiliser being contaminated by fixer.  Some people wash between developer and bleach but you really shouldnt do that as it can be detrimental to the process.

  Stabilising should be done at room temperature.  When you come to stabilise just pour it into your tank and rotate it by hand for the required amount of time.  I used to stabilise at 37.8C but i was advised by a fellow processor to do it at room temperature; to be honest though i cant see much of a difference in my negatives.

  The above steps should take you around half an hour to complete.  Once you're done you can take the lid off your tank and remove your film.  The film should be covered in foam from the stabiliser - dont wash this off.  Just hang your film up to dry naturally (in as dust-free an environment as possible).  Once its dry take it to your scanner or your enlarger and see how it looks.

  This tutorial is by no means definitive.  This is just how i currently develop my C41 negatives/cross processed slide films at home.  Im sure as time goes on i will home my skills in processing and change my process as i see fit.  If you have any quesitons feel free to post on this blog and ill be sure to answer them.

The Then and The Now

  It is a particularly slow day at work today and i find myself tired of looking at website after website.  My mind is drifting, looking back over the past year or so that i have been a photographer and thinking of the mistakes made, the cameras bought and the photos taken.

  I remember first getting into photography because my girlfriend (now my wife) was a keen photographer.  She had studied digital photography at college and i thought i would get a camera so we could go out on trips together, after all – she would come rock climbing with me, it was only fair i do things she is interested in with her.  I ended up with a Lomography Diana F+ as i liked the look of the lomo style photos and wanted a film camera.  I bought some rolls of film off Ebay (Fuji Provia and Ilford FP4+ if i recall) and got shooting.  I got my films developed at a local(ish) lab and started uploading my photos to Flickr. 

  As time went on i kept acquiring more film and shooting more rolls and i really enjoyed it.  Jess’ interest was starting to wane however, she very rarely picked up her camera anymore and when she did she just didn’t seem motivated to shoot at all.  As i got more and more keen i started picking up more gear.  A Jobo CPE-2  to develop C-41 film at home with, a Paterson tank for black and white developing, a Holga 120 WPC for panoramic pinhole shots, a Lubitel 166B, an Epson v500 to scan all my negatives and eventually my Bronica SQ-A kit.  The Bronica is my main camera these days, it’s just great to have a camera which i can change film backs/lenses on and which has apertures of f2.8 on the lenses.  Im getting into off-camera flash photography with it which is really interesting as it’s an extra avenue of investigation to take.  I feel like i have neglected my Diana lately though, perhaps i should shoot more rolls with it soon.

  I have also got into Polaroid shooting over the past 6 months or so.  I started off by finding an old Polaroid 100 integral camera at a local antique store for £5.  I got some Impossible Project film and got shooting.  Not so long after that i picked up a Polaroid 645CL 600 camera from the same store for the same price.  I stumbled upon a guy online who was selling 30 twin packs of Polaroid 600 film for £90.  Needless to say i bought it, kept some for me and sold some (mostly to pay house-related bills).  A few months later i discovered the Polaroid folding Land camera range.  Wow those cameras look great.  I scoured Ebay and found a 103 for £20 and bought it immediately.  I modded the battery and loaded it with some Fuji FP-100C and got shooting.  Not long after that i saw a 101 with case, flash and spare bulbs going in a local auction.  I placed my bid and won.  I have modded the battery but haven’t yet managed to load any film into it.  Hopefully i’ll get some soon and it will all be working fine; im looking forward to trying out the flash.

  It’s interesting to look through all my photos and see how i have progressed.  Some of my favourite photos even now are ones that i took mere months into my photographic career.  My favourite may well be this photo of Jess smelling a flower.  I took it with my Diana on some cross processed Provia 400 and i just love it.

  I think about all the technical mistakes i have made.  Developing black and white film in C-41 chemicals, pulling film out of my changing bag instead of the paper backing, shooting a roll without removing the darkslide-all mistakes i am sure many people have made.  But i guess we learn from making mistakes, even though we may feel stupid at the time.  I have got my black and white developing technique nailed now and im happy with how my C-41 negatives are coming out.  I’m still working on a definitive scanning process to improve the quality of my digital images though, and i haven’t even started to think about darkroom printing.

  Im not trying to brag about the gear i have or what i can do or anything, it’s just interesting to look back at where i started and where i am now.  The first time i picked up my Diana i had no idea that soon i would be developing my own film and shooting wide angle pinholes, swapping lenses on an SLR and doing emulsion lifts on Polaroids.  I can’t help but wonder what the future holds for me.  I would like to get a telephoto lens for my Bronica and maybe another flash and some extension tubes.  Maybe even a Hasselblad one day (those Zeiss lenses are so sharp).  I’d love to maybe even own a Graflex Speed Graphic one day and shoot some Collodion Plates.  Maybe one day ill even have my own darkroom and i will be able to do my own printing, which would open up a whole new world on toning, tinting and alternative processing. 

  Im thinking lately about getting shooting slide film normally instead of with a view to cross processing.  I have some Fuji Velvia 50 in my film box which i have cross processed every time i have shot it; perhaps it’s time i got it developed in E6.  I’ve also been working on some cyanotypes lately.  My wife bought me some Sunography paper, but i note you can get kits from Silverprint that you can use to coat your own paper; perhaps ill invest in a kit at some point soon.

  When im not shooting it’s nice to look around on websites like Flickr or THIAPS for inspiration, or the Strobist site for lighting technique.  Sites like APUG are good as well as it’s good to be able to advise others and get advice yourself from people who know what they’re talking about.

  But for now im content with what i have and what im doing.  Im happy being able to just go out and shoot with my different cameras and films; finding new locations and honing my skills, working on new techniques and improving my shots.   

  That’s my story so far anyway.  I’m sure that soon there will be something to add to it.

  I’d love to hear from you about your story, however long you have been shooting.  Feel free to comment on this blog or even email me about it.

Sunography and Cyanotypes

  It was my first wedding anniversary last week and my wife and i got each other a few presents in celebration.  Hidden amongst the graphic novels, jeans and camera-related treats was an A4 sized envelope of something i hadn't seen before.  It was a package of Sunography cyanotype paper.  A quick read of the instructions revealed that all i had to do was expose the provided paper in sunlight for a period of time, wash it and voila-a cyanotype!

  Well we had our first sunny day yesterday so i set to work.  I put a sheet on top of a hardback book, put some negatives on top and placed a sheet of glass over them.  I sat them in sunlight for 15 minutes and then rinsed in cold water for a few minutes.  For some reason some of the images rinsed off in the water (hmmm...) but one of them stayed and looked great.  Im really looking forward to exposing the rest of the sheets.

  I noticed this morning that on the Silverprint website they sell a kit that contains chemicals etc to make your own cyanotype.  It costs a little more than the Sunography paper but it seems you can get more mileage out of it and you get the fun of mixing your own chemicals and exposing them onto whatever material you want.  Ill probably be giving that a try at some point in the future.

  Im hoping to print one of my photos onto a large sheet of acetate and try and expose that onto the paper-hopefully it will turn out well.  You can place pretty much anything you like over it and expose which i think is pretty cool.  Purist cyanotypers may turn their noses up at this as i suppose its not really a true cyanotype but its quick and fun so i dont really care!

Return to Parklife

  TO THE PARK was the cry one lovely sunny evening a few weeks ago when my wife and i had finished all of the days chores with some time to spare.  Jess was in a rare film shooting mood and i wasn’t about to complain so we packed up our kit and headed to our favourite park – Worden.  It is a lovely large park and if you have read previous blog posts of mine you have probably seen shots from it.  

  The park is divided into several sections – football pitches, a wood, a miniature train area, a play area and the gardens area.  We only had an hour or so to play with before the light would be gone so we did some rapid-fire shooting, sometimes not even pausing to meter properly.  The flowers were just starting to bloom which made a lovely carpet for the trees to sprout out of.

  After developing the film i was very pleased with the results – the light is great on some of the shots.  Lets hope that when Jess finishes her roll her shots will have come out well too.
