What is wrong with this roll of Cinestill 50

So I posted this into Darkroom sub-forum last night but only got one reply (also uncertain as to what is going on) so I've also posted it here.

 

I got this back from my usual lab who have always done an excellent job for me in the past, well that was until they developed these two rolls of Cinestill 50 for me.  The two rolls are similarly affected.  Apart from the scratches, and lumps of crap which don't come off the negs easily, there is bizarre rounded brown outlined 'staining' readily visible throughout the skies.  There are no staining marks matching these on the surface of the negatives so they are within the emulsion.  These are reminiscent of abdominal X-rays of the colon....

 

 Needless to say I am not impressed   :angry:

 

The company will get an ear full over the filthy negatives but do the 'blobs' reflect a developing fault or could there have been something wrong with the film batch?

 

Thanks in advance.

Mark

Certainly need to wind them up about the cleanliness, for sure. I get negs like that occasionally, but I process them myself, so I am the one who needs the reaming. But if you are paying for this it must be better.

 

Not sure about the "other issues" though, but given the cleanliness of the negs, possibly old or not perfect solutions? Have you had any others processed, from the same (film) batch? I suspect not, but that might tie down the film or the processing.

Hi Gary

 

This is one of two rolls of Cinestill 50 processed at the same time,both look the same. I didn't have any other film processed with these.

 

It's a long weekend here so I won't get any explanation from them till Tuesday.

 

Regards

Mark

The bubbles are similar to those when the developer has frothed and there isn't quite enough developer in a normal Paterson type tank to cover the film fully, hence the froth being along only one edge. So did your lab hand develop the film, a fault in the processing machine maybe, did it need fresh chemicals? In fact the last problem of fresh chemicals is a concern for labs that don't have much colour film throughput, the chemicals don't get changed as often as they should. One question, can you see the bubbles on the film between the images and along the sprocket holes? This could imply a fault with the film, otherwise I'd say the processing at fault, especially because of all the crap on the negs as well. A final thought, the film has been dried far too quickly at a high temperature while there was still a build up of liquid on the surface of the emulsion.

Thanks Steve, 

 

this is (no longer by me) a very well regarded professional lab in Sydney with large workflow.

I'll discuss this with them on Tuesday.

 

I'm actually quite upset about this as the light and colours in the brewing storm that day were quite unusual for our part of the world.  Reminded me of the cold green-grey colours in those old WWII arctic convoy paintings...

Mark may be dirty developper and perhaps old , presence of product residues :angry:
It happens sometimes when developing in non serious external laboratories
My second remark is scratches
For this reason, if you can, develop yourself like me :)

Good photos and see you in our film thread

Thanks Henry, you're right of course, however I really don't think that at this stage in life I can commit to colour processing at home.  Perhaps in my retirement.

It looks like War of the Worlds out there, Mark, with the alien specks and bubbles adding a bit of Jackson Pollock to the mix. No wonder you are disappointed - Those are powerful scenes.

 

Unless there was something wildly wrong with the emulsion, it does look like a developing issue, and the amount of crap on there makes for a large aligning of the coincidence spectrum for it to be both film and developing issues.

Mark you are welcome

For these round spots , it comes from fixer perhaps also too old and insufficient washing !

 

It needs not too much place for developping yourself Mark.

One Paterson tank , water bath and resistor aquarium to maintain 30°C  with Tetenal . Very easy

and the pleasure to do yourself and a good work !

Mark and Eoin "yes you can"  * !

For me if I share in the tank Paterson (with 500 ml of products)

I can develop 15 rolls.
With 1 liter I can do 30 rolls. Total cost 1 liter = 30 Euros

1 Euro/roll and good work no scratches

The most important :  keep the product vial well closed
in cool place and protected from light.

No need to go to the lab closed on weekends

Mark , you are welcome :)

PM me when you decide to develop yourself.

Welcome to film club :)

It's so wonderful !

Here is my "water bath"  but you can also work with a resistor of fish aquarium .

(perhaps less space required) . I have it too as back up.

The advantage of 30°C is you can work with a resistor sold commercially.

it's less hot and less damaged products if it is at 38 ° C (also recommended by the

manufacturer)
