streaks on negatives

Early Riser · Dec 29, 2006

Are you using the same developer for all your film? Some developers get syrupy when they age, and even developer in powder form can get funky. They tend to turn brown when they get old, that might be a source of the brownish material.

Perfect? Of course!

Bleedin' awkward? Also 'of course'; you're female!

A couple more thoughts -

Do you used liquid or powder chems?
Do you transfer the film into your camera bag before using it? Same bag? Same type of bag?
This might be a really dumb question (yeah Frank, like the others weren't! :rolleyes: ) - Do you use any form of hand cream or moisturiser?
Any chance of posting a couple of digisnap examples?

It's clear that we have to embrace conspiracy theories! Could be the current administration, or more likely, Canon or Nikon... in a blatant bid to get you to "go d*****l"!!

Alright, I'm finally admitting defeat by posting a plea for help.

I've been developing film for years with no issues. Suddenly, the last six months or so, I'm fighting a very frustrating battle with streaks on my B&W negs.

Basically, I'm getting some sort of brownish residue on my negs that, when I squeegee, turn into ugly streak all the way down my neg strips. The residue does not rinse off easily, but does come off if I run my fingers over it. I haven't changed any part of my process in years, so it's not an issue of a new product or a change in work habits. It happens with all film brands and formats. It's totally infuriating.

Possibly not a great help, but something else to try. In this week's Amateur Photographer mag in the UK there is a guy with what he describes as sediment on his negs, but he's using a CPE2. Geoffrey Crawley's advice to him as a possible cure as follows:

"fix the film, rinse it with water and then rinse it again in stop-bath before proceeding with the normal wash cycle. Do not use a wetting agent other than in a brief final rinse before drying. Prolonged immersion in "wet" water can cause surface scum on the film. Never use the wetting agent at a stronger concentration than recommended on the label"

Have a happy and scum-free New Year!

Just wanted to give an update.

I finally got a chance to develop a test roll and started with Peter's suggestion of stop-bath, normal wash cycle, then brief wetting agent. Guess what?

No residue! Streak free and perfectly clean. Peter, I could just kiss you.

Thanks to all for the suggestions and offers of help!

Hey Cheryl, that's the best cyberspace offer I've had this year , but all the credit goes to Geoffrey Crawley. Great to hear it worked out for you!
