Another 'what happened to these negatives?' thread

[Sirius Glass]

I thought I'd post another follow-up now that I've scanned my latest set of negatives.

I'm happy to report that I don't see any streaking on any of the 38 frames I managed to squeeze out of my latest roll of Tri-X.

I followed the same dilution of HC-110 (H), development time (9 minutes) and initial agitation (continuous for the first 30 seconds, 4 inversions in 5 seconds at the start of each subsequent 30 seconds) that I followed on my last successful roll. It looks like this might just be a successful formula for me.

I've got another test roll that I shot a few weeks ago that I'll develop next and, if that goes well, then I'll start to work my way through my backlog, which also includes a bunch of 120 film that I've yet to try developing. Hoping that things continue to go well.

Thanks to those who have been following this thread closely and have offered up their expertise. The amount of knowledge and experience on this forum is mind-boggling and newcomers to home development like myself are lucky that you're all willing to share it.

I'll post back with another update once I get a few more rolls under my belt.

Great news!

Well there is a thread by Alfredo Dorrichi quite close this one in which he uses HC110 on a kind of minimalist semi-stand process. Most if not all semi-stand faithfully use the one minute continuous agitation at the start and it seems to produce good results

So it may be worth trying this regime. Have a look at his pictures if you haven't done so already

Thanks I'll look into it. Ironic as I've always considered semi-stand as a call for trouble but it gives very interesting results when it works!

Good news for you ! I am surprised though as I have been down that road many times (1 minute initial agitation and developing times over 10 minutes) and it did not solve anything in my case... It just makes the streaks less noticeable. What do you shoot for your test ? I fill the frame with a gray card that I overexpose by 1 or 2 stops to get the density when the steaks are more apparent. I find that as they are not in every frame it is hard to be sure otherwise.

I've primarily been shooting scenes with lots of cloudless sky. Those are the sorts of images in which the streaks have been showing up most readily.

It's certainly possible that the streaks could return, but I hope not. I've had two rolls in a row now where no streaks have shown up. Prior to that, I had shot around 10 rolls of film, all of which showed streaks on at least some frames.

I'm keeping my fingers crossed. Here's hoping that you start to have better luck too.

I’m just catching up on this thread after a spell away. Really pleased that you think you may have cracked the problem.

But I'm really puzzled by the photos you showed in post #158. You seem to have streaks running vertically in some frames and horizontally in others. Is that right?

Yes, that is correct. Puzzling indeed...

If you have streaks in two different directions on the same roll, it's probably not an artifact from processing. Internal flare in the camera/lens?

It's been a long thread and you may not have read it all, but I was getting similar streaking patterns using multiple cameras/lenses.
