E-6 development question

Stephen Prunier · Nov 22, 2008

I just finished developing two rolls of Velvia 100 at the same time. I watched the temps and did everything like I usualy do. One roll came out looking fine (it's drying as I write this) the other looks like it was tie died

I have no idea what could have happend. I have developed around 15 rolls of E-6 and this is a first time something like this has happend.

Any ideas would be much appreciated

Thanks

This wasn't the last roll from your last Grateful Dead concert was it Sorry, I really have no clue what's up with your problem

If you can confirm that you had enough chemistry in your tank to cover 2 rolls, then the only possible explanation is that the film was wound on the reel incorrectly and the layers were touching during some or all of the process.

Posting a scan sample of your film would probably completely clear up any further questions.

The number at the same time is irrelevant, unless you tried two back to back on the same reel, perhaps the tie dyed one hasn't had enough blix, try it anyway.

The colour dev is the only real critical step, Ron (PE) will disagree, all steps are of course important, but when you buy a kit you only have limited control anyway, all others are effectively to finality.

You need to say how you dev'd two films, what in, spirals can ride up centre columbs in tanks, you can use the wrong volumes, solutions can be exausted.

I had two rolls in a two roll paterson tank with 10 oz of chemicals. I use the 3 step from freestyle. I'm also wondering about the film touching. I think when I was loading the film on the reels one of them was stuborn going on. I bet that was it.

At least I wasn't "driving the train high on cocain" LOL

In a two roll tank in separate spirals the films can't touch

However you do need to use 10 oz per film that's 20oz in total, we always use 300ml per film in the UK, so 600 ml. So the top film has been developed only by splashing from the agitation.

The base of the tanks says - For Each Film: then gives the volumes but to be fair it's not predominant and could easily be missed.

LOL I thought it ment 10 oz filled the tank! Oop's

I don't see where you said if it was 135 or 120 film. In my tank, 10oz would probably cover 2 120 films but it wouldn't cover 2 135 films.

The two 120 films are both put on the same reel, so that couldn't be the problem there. It has to be 35mm.

If that's the worst you do today, don't worry about it.

Here's Stephens give away:

Paterson System 4 & Super System 4 tanks all use: 10oz /290ml for each reel of 35mm film, 13 oz /370ml for 127. and 17.5oz /500ml for 120.

The ounces (oz) are in fact British Imperial measure, the US ounce is 4% greater in volume, so that would makes little difference, I prefer to add slightly over the minimum requirement.

The very much older Paterson Major II series of tanks introduced in 1956 are far more economical, and I still have 5 or 6 tanks which I used for E3/4 processing in the early 70's, in comparison they require 300 ml for each 120 spiral, and 185 ml (6 oz) per 35mm, that's 40% less solution per film.

Thanks again for all the feedback. I'm not happy that my cost just dubbled! LOL

Use a Jobo or similar tank that is meant to be mounted vertically in a rotary process. The chemical volumes you need to use for upright processing is ridiculous in comparsion. If you don't want to get a Jobo you can get a uniroller base off Ebay for cheap.

Wait till it dries. I've found some funky color casts which have gone away after drying. If it was on one roll but not the other it indicates: lack of chemistry, improper winding, or fogging of some sort. Were they both treated the same pre-development?
