Hello all,
I developed a batch of 4x5 sheets last night (Kodak Ektar 100), and three of the negatives had large blobs on the same side of the film. The blobs are not identical. I used the Unicolor C-41 powdered kit.
This Is the third time I have developed sheet film in the Yankee tank, and I haven’t seen this yet. The interesting thing is that some of the negatives came out fine, and some had the blob. The blobbed negatives were all from when I took a long exposure of the sunset (see scan). This leads me to think it was not a chemistry problem, though the translucent lines were making me think I had under filled the tank or improperly agitated.
It’s looking maybe light a leaky film holder? Would love any input! The fact that they are all in the same spot makes me think that I did something wrong making the long exposure (I’m using a Graflex crown graphic).
Im kicking myself for not taking a picture of the negative itself before I left town, but if no one answers this today I will upload some.
here is a link to a scan. My phone is not allowing an attachment.
