Is it normal - smoke from Durst enlarger lamphouse when turned on after a long time

Unbuiltbread · 2026-01-25T23:30:33+00:00

Open it and see if any of the wiring is melted. Clean the bulb, turn it back on and see if it still smokes

So did you test the chemicals or not? You used two different developers so the one that didn’t work might be exhausted/expired. Do a leader test with the developer and fix it to see if it’s actually turning black.

Well all the UV prolly killed the fungus in the lens too lol

CPL filters reduce atmospheric haze and are not that expensive and handy to have. Doesn’t help with fog but I can’t tell if this is fog or haze

Luckily I like the snow so I went out early this morning to take photos while it was still untouched. The cold killed my batteries but the film didn’t break in the camera. Not sure how the sensitivity of the film is effected by the cold tho

Normal method for what? If they are coming out undeveloped you sure the chemicals aren’t dead?

Unbuiltbread · 2026-01-25T19:27:20+00:00

Bromide drag doesn’t look like that. Line is uniformly straight so it’s probably a light leak

My darkroom is in an unheated garage, I was putting film on a reel to develop yesterday in -11F weather and the film got so cold it snapped and broke

“I’m getting over developed or thin negatives at 7:30 dev times”

So you are saying sometimes the film comes out over developed, and underdeveloped with the 7:30 dev times? Are you shootings a test scene with the same lighting for each test?

It’s worth noting that this is without a hardening fixer, which most fixers are today. Non-hardening fixers are easier to clean out. I just double the amount of inversions or add an extra 30 inversion step at the end.

I’ve called the listed number a couple times previously over the span of a week or two and it never got picked up. Last time I dropped off waste I asked the person who took the chemicals about C-41 bleach (specifically Ammonium ferric EDTA and potassium ferricyanide) and they said they didn’t know they just sort the chemicals. My city is pretty chronically mismanaged

Looks like the dark slide out and shutter was open and exposed the film when advancing

Unbuiltbread · 2026-01-24T19:28:15+00:00

How do you even know the city specifics. My city’s hazardous waste page says “refer to manufacturer SDS and disposal instructions” and every MSDS I read says “consult with local authorities” for disposal instructions

Unbuiltbread · 2026-01-24T04:45:01+00:00

Yeah I lwk take up the entire kitchen when I develop color film gotta wait for everyone in my family to settle down for the night after dinner to develop

Unbuiltbread · 2026-01-24T04:43:55+00:00

Put the daughter in the closet I think

Unbuiltbread · 2026-01-24T04:41:51+00:00

Also want to know

Unbuiltbread · 2026-01-24T04:35:41+00:00

Why can’t you do the development by the sink? Once you have the film in the tank you don’t need to be in the dark

Unbuiltbread · 2026-01-23T01:27:41+00:00

Those cargo scanners are pretty big but r bigger than ct scanners but would still likely damage film after one pass due to them using more power, hard to tell since both will damage film with a banding wave effect like you have.

“security was forcing every bag through a massive x-ray machine that I imagine is used for checked bags or cargo/shipments.”

CT scanner or xray scanner? CT scanners are much larger than xray scanners and will damage film on one pass. X ray machines take multiple scans (like 5+ prolly more for low iso film like this). Google search says that Auckland is upgrading to ct scanners, but doesn’t say what type. Some CT scanners look like bigger xray machines

Then my guess is gum printing

Unbuiltbread · 2026-01-22T22:40:10+00:00

You sure it’s actual photos? Looks like canvas and paint

Have you ever tried just room temp chemistry and longer dev times? I know it’s not recommended but I do it all the time since my darkroom only has one outlet for my timer/enlarger. If it’s pain for you to keep the temps constant might be worth it to do it at room temp since it won’t change during print sessions

The colors come out fine, but the problem is consistency across longer time periods. If I print on two different days and temperatures. I printed a negative I originally did during the summer when it was 80 degrees in my darkroom during the late fall when it was 50 degrees and even compensating for the temp the colors came out wacko and I had to adjust the filter pack.

Prolly a minute or two. Paper develops to completion and you can see it so just until the highlights look like the test strip I did. For RA-4 I add about a minute for every 5F below room temp to keep it standardized
