Artifact (dark ray) on Negative

[Tim Povlick]

Greetings,

Was out hiking this past weekend with a Crown Graflex 4x5 with Schneider 135mm lens. The scan attached shows a ray across the image. I was thinking it was a light leak but it's darker and not lighter as one would expect. The holder is a Toyo. The sun was just over my right shoulder so it would have leaked into the holder at the dark slide. I've checked for bellows light leak and it's 100% tight. Not sure what this is.

There are a lot of problems with dust on this image as the holder managed to drop a short distance into the very dry / dusty ground. I realize the foreground is a bit of waste but walking into heavy brush with rattlers about wasn't a risk worth it.

What is your development process? It is nice to have all the info before we start guessing.

Yes, that might help... I used a Combi tank, this was only negative in tank. Developer was R09 one shot mixed 50:1. Development time was about 10 minutes with agitation about every two minutes. The Combi works well and I've not had this problem with it. Also use a Jobo 3010 but didn't use it for this go.

Thanks

Tim

The posted image of the film is showing up as a positive on my screen. Either way it is likely the cable release.

Interesting... For this image with the Crown Graphic I used the side mounted shutter release. I think the cable is pretty much out of the way but your idea of something in front of the lens makes a lot of sense. Perhaps a small twig was in the way, or something like that.

We'll call this one solved! Thanks very much for your help.

Best Regards,

Tim

I disagree -- I think it was a long exposure and a large black eagle diving down to get a rattlesnake on its way to bite Tim.

It just wasn't his time! =)

sorry for the thread hijack but I also have odd artefacts in my image. This photo, my 2nd ever in LF, was taken at night and developed in the day using a homemade tube. I cant for the life of me understand the light pattern, what could have caused that? The one obvious thing to me is maybe when I swapped from developer to acid stop, but the negative didnt even leave the tube and light was getting in for less than a second, unlike how he does it in the BTZS videos.
I took my watch off and transferred the film at both steps in a dark bag in a dark room.
Maybe the holder is faulty? TR hot spot is a street light.
it's odd how the two horizontal lines both end on the diagonal where the deck ends (this was taken looking off a deck. the silhouette is an off spotlight, the large squarish white thing below is a broken table top).

Also, bottom right, I suspect those are developing marks. Agitation was hard for 10 seconds, then 6 rpm, directions changed every minute for 12 mins, rodinal 1/50.
