[Frameworks] E-6 Imperfections

[nicky.hamlyn at talktalk.net]

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?

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

Hi all,


I've been doing a lot of Super 8 developing for people over the last few weeks. The last two film I developed last night had an interesting imperfection and I wondered if anyone on frameworks could shed some light on what's happening.


The chemicals were mixed on the 1st and as far as I'm aware the chemicals are viable for up to 2 weeks. I've actually developed film with chemicals 3 weeks old and got fantastic results. However I'm developing other peoples films so I'm not developing past today/tomorrow at the very latest. I've got 4 more films I need to develop tonight and tomorrow night.


Last night I developed my 7th and 8th super 8 film in the tank (apparently you can do up to 12 with one liter), but anyway I wondered if this could contribute to the problem.


So the problem... 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? 


Could light be getting in the tank somehow? If anyone has come along this effect in the past please let me know.


Thanks
Kevin
