[Frameworks] E-6 Imperfections

Wed Feb 15 13:49:44 CST 2012

According to Martin Baumgarten (and other sources you should be adding developer time as you exhaust the chemicals:

~~~> BLACK & WHITE Film Processing Control <~~~

(1).   The best way to maintain control of your processing for any 
process type, is to keep track of how many films you have processed in 
a given solution and either replenish the solutions so they maintain 
full-strength and/or adjust your processing time.  A Liter of chemistry 
will process about 6 to 8 rolls of Super 8mm film.  After each roll of 
film if processing separately, add approximately 15 seconds to each 
Developer time only.   Or after processing two rolls of Super 8mm film, 
add 30 seconds to the next film batch.  These are approximations 
intended to quide you to correct final film density. 

He also recommends creating your own control strips so you can keep track of the density. He describes that process on that link. I've never done that but if you have a large amount of film to process its probably worth the effort.

I'm pretty sure "Sixty films" refers to 36 exposure 35mm slide films, not Super 8 films. One 35mm slide film is about 1.3meters long, which roughly equates to five meters of Super 8, whereas a roll of Super 8 is 15 metres long. That means a 5 litre kit would process about twenty rolls of Super 8 and a one litre kit only about four. (Correct me if I've blundered with the sums!)

Oh right, thanks Nicky 

On the box it says that the 5 liter kit can process 60 films. I did the simple math and figured that 1ltr should process 12 films with good results. Apparently not! Seems a little cunning to state it can do twice the amount the chemicals are capable of!

I think you may be over-using the chemicals, assuming it's the Tetenal three bath kit. If you do the calculations you can do up to six rolls safely, but strictly five rolls, if I'm not mistaken, so the sixth is a bonus. After that you're gambling with exhausted chemicals,

Hi Erin, 

Indeed I am using a Lomo developing tank. I did checked the spacing of the film on the reels whilst hanging it to dry and all the film looked perfectly mounted. However I suppose it could have shifted and re-shifted in the tank during the reversal process? I don't know if this will help but the brown bits aren't as visible on the lighter (outdoor images) but are worse on the indoor images. For example one roll of film (100D) was used indoors and it was inevitably very dark anyway. The brown transparent layer seemed much more prominent on these darker images and was much more noticeable.

Can that tell me anything?

Kevin

Hi Kevin,

Are you using a lomo tank?

Your problem sounds like the same one I have had with both E6 and B&W reversal in lomo tanks.
I think those brown bits are occurring anywhere that the film slips out of alignment and touches an adjacent piece of film for too long. 
Neither bit of film is then making proper contact with the processing chemicals. 
Further, this seems to be happening somewhere in the reversal stage. 
In one case I actually had this layer going on for a while with bits of negative and positive imagery appearing throughout it. I inferred that that the film was making proper chemical contact at various stages of the process, but not all. That was a particularly poorly loaded tank.

In the case I have described above, the brown stuff is opaque and seems almost thicker than the rest of the film. On other film stocks it appears as different colours.

Strange that you only had this problem on your 7th and 8th rolls, but less strange if you processed them together. Maybe you are encountering something totally different.

Hope this helps,

Erin

Ok now the films have come out great overall but in parts there seems to be this light browny kind of layer that fluidly move across the image, in parts it's centralized and in others it's on the edges. Like I say overall the images are clearly visible and sharp without much grain but there just seems to me this brown mask that intermittently comes and goes. It's present on both films I developed. Any ideas?
