Light leak on Cinestill800 or something else?

[Frank53]

Usually I do not use any color negative film, but reading about Cinestill800 made me curious, so I decided to try a roll on a short trip to London. Most of the film came out fine, also by dayligh (the deer)t, but a few negatives showed something that looked like a light leak (at the end of the film) and a few some strange blue kind of lightningish effect (at the beginning of the film).
I'm almost sure it was not the camera, as I used it for b/w film before and after this film. Could it be something during development, the x-rays while checking in and out the Eurostar, or something else?
I just did a quick scan of the negatives, so there is some dust annd quality is not so good, but good enough to see what I mean.
Regards,
Frank

Surely people more experience than I will chime in, so don't take my word too seriously, as I may be wrong.

The red to me looks like a light leak.
The blue looks like it could be artifacts from static electricity, but it also almost seems like a drop of liquid (developer, perhaps) that started to spread down.

Frank 53 - hello again......

Well - Frank a light leak to every emulsion
isn't very hard to identify.E6,C41,bw.
You will have the same structure of damage to some frames becomming less
and more less to the rest of frames.
Or it goes in the oposite direction (to become more and more) - of cause.
Is that the case what happened.
From your scan it is 100% a light leak
or it is 100% a instagram filter.


with regards

I've seen the blue light flash on Cinestill 800 as well, I think it is related to the cleaning/processing of ECN2 to a more c-41 friendly environment. (removal of remjet).

I do shoot the Vision3 500T and I have never seen anything similar on that.

The price for Cinestill should almost render you qualified for a refund when you get several frames ruined IMHO

Ähhmm.....forgetting to say :
Your camera is still fine Frank? So it was your lab .... before you went back to your lab to make "the four flagged MOST
TROUBLE OF THE WEEK" you should check your camera again.
Are your bw films often like PanF ?
Are you shooting ISO25 Films ?
The max. since all the last years is
ISO 100 with Tmax and Delta100 ?

Then we have it : ISO 800 .....

with regards

 

[Frank53]

Thank you for your replies. So it could be something in the proces, of removing the remjet or the development.
I have one more roll of this film so I will use that soon and have it developed. I'll see how it comes back.
To be sure, I will load and unload the camera in the dark.

About the camera, it seems fine to me, use it a lot with fp4+ and hp5+ on different iso's. Sealing was replaced a few months ago and no problems after that.

Regards,
Frank

I forgot to mention that I process my own c-41, regular daylight tank, Tetenal c-41.

Blue lights are definitely something from before the film sits on the shelf in the store.

My guess; static discharge from high-speed rollers, post remjet removal.

So there is a chance, more of these films have this problem?
I will see how the other roll comes out.

Lightning in a random frame from the Cinestill 800 I tried.I think I had 1-2 frames more with this artifact, I deleted those scans.

 

[MattKing]

Cinestill film is motion picture film that the Cinestill people buy in bulk, scrub the remjet off, and then cut and package in 135 (aka 35mm) cassettes for use in standard 35mm still cameras.
Remjet is really designed to be removed at time of development, not prior to exposure, so it doesn't surprise me that there would be some instances of unwanted effects in still pictures taken with it.

Frank just out of interest : Your reported problem with electrical charge should have been an interims problem havn`t it ? What is your experience is it solved meanwhile ?

I just can´t find new infos about this....?

with regards

I never had this problem - but I bought not so much cinestills due to budget

I did not use any 35mm cinestill after the first film and the problem did not go away so it is still there.
I did use 2 120 films and did not like what I saw, but have to sort it out. Looks like you have to be very careful changing the film in daylight.

Ok - I understand. Well daylight isn't the real thing to tungsten ballance of cause.
I have used it instead of EPY on night sceenes.

As much as I like CInestill film (used ~10+ rolls on both 500T and 50D), it is just too fragile and the question about long term archival bothers me... so back to Portra.. also trying Natura 1600 for 35mm (yes, I know it's being discontinued, I have a freezer)..

Those red bands look like a light leak through the felt light trap, or perhaps a little light piping since there is no more remjet and no anti-halation layer to stop it. Those are kinda important so they are put there for a reason....

Not sure why people buy the film other than for fun. The way they should have done it is leave the remjet on it, and sell the film with processing paid. You shoot the film and send it back to them to develop it in the appropriate chems. That would be a winning solution, and the cost wouldn't be much more at all. Kinda dumb the way it is now. And in the long term, people will stop using it due to problems and there goes your business model.

Well - Patrick Robert James - I like this film very much.
I see this very different from you. And I will explain a bit, hope you agree after this.
At first I like EVERY new film with one simple exeption : Foma Retro Pan320 .
This film as a brand "New" film is a little nonsense to me.
Cinestill is in basis of Kodak Vision III.

It is indeed the best emulsion today.I just remember Vision II as an emulsion with remarcable characteristic.The inproved version is in some parts much netter.
What Cinestill was doing with this film is within their own interests.They recall film into life back again to many new users and make a lot of money.
The technical problems ? So what - there is a need to make this film uncomplicated to the mass.
Remember one post of a younger guy with just digital experience.
He ask if it is possible to change the speed? Of cause it can be done with films.Therefore the iso adjustments.
My old Pentax LX has a range from ISO
6 - ISO 3200. EVERY 2nd Frame I adjust a speed wich I prefer .

The longtime stability is such an other issue, because this films are mostly scanned.
So we won't tell them about long time stability with digital archived data...
On the other hand - many of new film users don't care about long time affaires from film archivements.
At least I can understand the way cinestill went.
But at one point my tollerance is not enough : The new pricing to Cinestill800
I just have seen $ 16,99 from my local dealer..
But to us - it seams to be no problem :

....just ask our dealers to order this stuff to us !

 

[trendland]

If you'd like a bit more speed ?

NO PROBLEM AT ALL :

Well - I AM ABSOLUTELY NOT AFFRAID OF........

If you like Natura 1600 I would give you following advice : You shot 20 Natura 1600 per Year ? Perhaps it is just 4/year ?
Best way : RUN imedately to your dealer and order a batch of 80 rolls.
Because you have today a lower pricing than we will see in the next few month.
Because you will have your stuff to the next 20 years in your freezer.
Because you won't have a change to get this film next year at the same month now.
But it may be some Ebay sellers will offen it to you next November?
To 24 bucks a simple roll.
DISCONTIONUE IS STILL PREPARED !
