Developing Color Slide Film (E-6) at Home

The "world famous" Macs Diner - Expired Fujichrome Provia 100F

by Mat Marrash

Just a month after finishing a project in B&W film and nearly a year exploring new color negative films, I’m starting to notice just how little attention I’ve been paying to slide film (insert sad face here). Each time I would start shooting some, the excitement of vivid colors on a positive image were quickly overtaken by thoughts of time wasted and more money spent. Regardless of overall quality, sending out your E-6 to be processed is time consuming, and can get expensive fast. And though I love my color lab for their quality and consistency, there are times where cutting out the middle man and saving a buck just sounds better. Enter in the world of home processing. For a minimum start-up cost, a warm sink, and about an hour of free time, you can start processing your own E-6 film at home.

E6 by Film Photography Project

Let’s start out with the issue of cost. In the US, the average cost of having a roll of 120 film processed in E-6, no prints, no scans, etc. is about $8. This isn’t including the two way shipping costs, and other mailing materials; if you use a pro lab service, this can be reduced significantly, but it’s still a consideration. If you’re shooting multiple rolls of film, E-6 labs often do not begin to offer price breaks on pricing until you’ve sent in 10+ rolls of film for processing. For today’s non-professional film shooters, this is quite a lot of film to have run at a time. By the time it’s all said and done, it costs ~$12/roll for 120 to be processed, $15 if you’re having the slides cut and mounted. With home processing, however, you control your own cost per roll rates, and with a little chemistry “stretching” can reduce your cost to little as $3/roll!

Interested yet? Well just in case you’re still on the fence about chemistry, materials, and space, don’t be. If you currently process your own B&W film, you’ve got almost all the supplies you need. If not, you’ll need a daylight processing tank such as a Patterson tank, a thermometer, and film squeegee, capable of handling whatever size films you plan on processing. Next, head over to the FPP to find home E-6 kits right in The FPP On-Line Store ( ) Don’t be scared, it is $30, but treat it nicely, and it’ll reward you with months of quality slides. Alongside the chemistry, if you don’t already, you’ll also need some 1 Quart Bottles, to keep the chemistry as oxygen tight as possible during storage. Lastly, and most important, is warm water. If your sink, shower, or tub has the ability to give you a modest, warm bath, you’re all set. If it can maintain said warm water within +/- 1 degree Fahrenheit, so much the better.

So this is it, you’ve got your chemistry mixed, bottled, and film loaded, all that’s standing between you and some tasty chromes is temperature and time. Here’s what you need to do: (all of this and more can be found in the data sheet)

Heat the Chemistry - Draw a warm bath and try to keep the bottled chemistry covered 50+%. During the wait to get the 1st developer to temperature, drop your thermometer in and go load your exposed roll of film into the tank.

Prewash the Film - 1-2 minutes of water @ whatever temperature you will be developing at. I always use 105 degrees Fahrenheit, but you can go as low as 70. Be prepared for awesome looking rinse water!

1st Developer - This is the most temperature critical step, so either wait until the chemistry is just a tad bit over your temperature and add it in, or add it as soon as it comes to temp, then bathe the tank periodically between agitation. Color film agitation is much the same as B&W. Vigorously agitate and tap for air bubbles for initial 15 seconds, with 5 inversions every 30 seconds thereafter to completion.

Rinse - With water roughly the same temperature as your developer, fill and empty the tank at least 7 times.

Color Developer - Slightly less temperature dependant, this step should be carried out as close to developing temperature as possible, with fluctuations not exceeding +/- 5 degrees Fahrenheit. Agitate same as 1st developer, and go to completion.

Rinse - Same as above.

Blix - Unlike traditional 6+ step E-6 kits, bleaching and fixer have been combined to a simple, single “Blix” step. The least temperature sensitive step of the process, blixing can be done with the daylight tank open, but just watch your time.

Final Wash - It’s happened to the best of us, you’re too excited, you just can’t wait, and want a sneak peak of this magical E-6 process. You only have to contain your excitement for 5 minutes more, you can make it!

Drying - Squeegee your film, at this point it isn’t completely stabilized, and may appear a faint navy blue where the density should be jet black. Don’t worry, this is normal. Just try not to touch the emulsion side, hang up to dry, and use only air drying without heat! These films are very sensitive to hot air, and will become reticulated beyond saving if too much heat hits them early on.

This may seem like a long, drawn-out process, and some may argue that it is. But like anything else photographically worth doing, this requires patience and practice. Start out with a fun roll of E-6 shot through a Lomography camera or a batch testing roll (like you’ll see throughout this article), and work your film up along with your confidence level. As stated above, you can "stretch out" this kit by processing more than the 10 rolls per kit stated in the Arista data sheet, but be sure to compensate with your processing times accordingly. The images on this blog are all out of roll #17 from my first Arista kit, so always take recommendations with a grain of salt.

About Mat Marrash
Starting in June 2010, Mat Marrash, a Northwest Ohio native, picked up a medium format film camera and challenged himself to shoot at least one roll of film per week. In the weeks and months following, a healthy interest soon became a lifestyle. During his project, Mat tried out a variety of traditional formats including: 35mm, medium format, large format, instant photography, and even alternative process darkroom printing.

If ever I needed an excuse to add colour to my home developing... Great write up Mat.

Nice write up! I have 5 exposed rolls stacked up in the fridge waiting for enough money to develop them. At $10-13 per roll, they could be chilling out for a long time... so I've been thinking of buying one of the kits and just DIYing it.

I usually shoot black and white so I was thinking of getting the 1 pint kit which would be a good size for my 5 rolls, but my Arista plastic tank requires 590ml for a roll of 120, more than the kit makes. Anyone encountered and solved this particular problem before?

Of course I could just get the 1qt kit for not much more, and shoot some more E6, my worry then would be the shelf life of the mixed solutions and having it go sour before I get close to capacity. What kind of shelf life do these have once mixed up?

Cheers! Paul.

Treat your E-6 kits like you would any B&W chemicals. Anything over several months old without any use will start to show signs of its age, color shifts, etc.

The recommendation of the kits is for 8-10 rolls within its shelf life, but I've done now 17 rolls through my first kit with some pretty good results. Starting to notice magenta highlights and purply shadows, may have to get a new kit soon.

Great write up, Mat. I just bought a Pentax 67 and the seller was kind enough to throw in some Velvia for me. I've tried cross processing a roll but it didn't work very well so I'm going to give E6 processing a try. Cheers, Nasir

This is great! I would LOVE to see the same thing for home C-41 also! Thanks, ---Alexander

Thanks for the write-up! I've recently scanned my last two rolls of Velvia and now I want to shoot more. Much more! Developing at home seems like a good idea to reduce the costs.

Hi, Any idea where to get this kit in Canada? Looks like freestylephoto won't ship here :(

Thank you for this. I did not know you could develop E6 at home. Cheers Steve /

I have a pair of questions... What kind of safe light should I use when getting the film out in the darkroom? What time is the processes for 30 C?
Billy Bob's picture
Sorry Tuum, But this is color film. It reacts to all colors, so no light is safe. Loading must be done in complete darkness or a changing bag.

We lost Universal Color here in the Minneapolis area on 3/13/13. They were just about the last bastion of E-6 processing locally. This post will be key in getting me on track. Pretty much everything needed to get started is here. Thanks, Mat!!

I have a 1 liter Patterson tank. Will the quart kit be enough for the tank? 1 qt = 946ml.

Great finding this site! I have been wanting to do this for a while as I shoot MF and recently LF in 4x5. If you would like and have the time, please visit my site at It will probably take me a while to get everything in place, will let you guys know if I get it right! Thanks for great info! Anton

Great write up! I went ahead and bought some the Arista E6 processing kit and so far have developed two rolls. Never developed E6, only B&W, and I'm having some learning curve adjustments: 1. First roll came out way too light with greenish hues, can't make out very much. I think what happened was the temperature fluctuated too much. 2. My second roll came out kind of milky looking, the whole thing is a little pink too. The images are much better on this roll but overall too light. I kept everything at 105 this time, the only think is I may have pre-washed a little too long. I'm hoping my next roll comes out better, what can I do differently to get away from that milky effect and get better images?

Using this type of Unicolor Kit-- can you offer any suggestions for getting the best possible images when developing old 35mm exposed Ektachrome E6-- its just been stored at room temp in its plastic film canister
David's picture
I got two kits, with the first kit, I developed 20 35mm/36exp films, all at 105° of curse the last films were developed much much longer than the firsts, I have loaded 20 more films, ready to start with the second kit, by the way all results were excellent, just last film a little dark (needed more development time) but still acceptable.
