Any idea where this yellow tint came from?

[Huss]

The yellow haze/tint on the bottom middle of the image. This is on three rolls of the same film that I just got back. Camera lens is clear/colourless.
I have written to the lab that dev/scanned the film asking them to take a look, but until I hear from them..

Thanks!

FYI Fuji TX1 w/ 45mm lens and no center grad filter (it had not yet been delivered)

Looks like you have it on the top as well.

Do you have any bright areas around the film gate that aren't blacked out? It almost looks like the beginnings of a light leak or flare. Since you cant see anything on the rest of the film it would lead me to believe that the issue is around the shutter.

 

[mpaniagua]

looks like light leak to me. Also, is the film expired? probably could be expired related issue too.

Pepsodent three times a day for three weeks will have you wondering where it went......

Sorry, old fart joke.

Is it every frame? Same place? Looking for a pattern.

Thanks for the replies. The film is expired, but other rolls from this batch were fine. This happened on all three rolls I shot. On every frame. But it could be the film..
Not sure how a light leak would be yellow? But I am open to this being explained to me.
The TX-1/Xpan has a 'modern' metal blade electronic vertical shutter and all the exposures were spot on. I'll check the back door's seals.
Thanks for that suggestion.

Its my observations that light leaks on color neg can turn out red, then yellow then fade into white.

I'm thinking that perhaps this is what we're seeing. But I don't think the leak lies within the back door otherwise you would see the leak across the entire strip of film. Since the "leak" (were assuming at this point) is contained within the frame it happens at the time of exposure, or after the film is advanced and waiting on the next shot.

I'm thinking with a leak like this it could be a lens mount or perhaps internal reflections from inside at the time of exposure.

if you dont see any obvious points of reflection try giving the lens a tape around the base where it meets the body and see if that makes a difference.

Do you find that the yellow cast is stronger on frames that you waited longer for between shots?

 

[Huss]

Hmm, interesting. The TX-1 (and Xpan) winds all the film out, then winds it back into the cassette as shots are taken. I did not notice a difference on time taken, as the rolls were all shot within a few hours at an event.

I will shoot a test roll of fresh film and see if I still get that issue. Of note, I did not use the central nd filter with these images as mine did not arrive yet. That means that the center area of the frame received more light than the sides. But still the issue is on the center edges.

FWIW the camera looks to be in immaculate shape, barely used.

I'll shoot the test roll and see if it still there. Again, much the advice is much appreciated.

It could be a light leak, but it looks too smooth and covering too large an area for it to have happened in camera. It's not a common pattern for light leaks, is what I'm saying.

This may be a development problem. I had some yellow patches on a roll when I first started processing C41 at home and that affected large patches of the negative like this. I tracked it down to uneven development, which I think was caused by using the wrong tank core combined with my general sloppiness. Basically, a patch of film was in contact with the developer for longer than it should have been. I also suspected I didn't carry out the bleach-fix step for long enough.

Can you post another couple of images? It would help to see if the yellow patches are in the same position on each frame.

 

[Huss]

I was thinking development as all three rolls show the same result. Another shot, one that I actually like but still wish that the yellow tint wasn't forced upon me!

Remember, this was shot w/o the vignette correcting filter (even though it was f8 or so) so the center area is brighter than the edges. The difference in exposure between center and edges is about 1 stop, so this brightness difference may have accentuated the tint.

The yellow haze/tint on the bottom middle of the image. This is on three rolls of the same film that I just got back. ...

Looks like heat fog to me. No untypical of out of date film.

It should be somewhat correctable in a good image editor (e.g. Ps, ...) or even Lr. Its just a matter of masking the correction layer(s) well.

Expired film?? Sorry, but you take your chances. Could have been how that particular roll was stored. Could be heat related. It is tough to tell since it is expired film. It can do all sorts of wondrous, and not so wondrous things. Can be that particular roll is breaking" down sooner then the others.

I do take my chances, but all this film was from the same batch (recently shot) with no issues (but never in this camera), and these three rolls suddenly show the same problem.
Which to me suggests something else.

I need to learn how to do that, my LR skills are weak. Which is why I like shooting film!

This one shows a similar pattern of yellowing to the first one you posted, so that may rule out a dev problem. Could be a light leak somewhere in the development process or like others have said, caused by the way the film expired.

Interested to see if you manage to narrow down this problem.

You are scanning with the entire film border.

Mask off the film borders, scan again, and see if the problem disappears.

While oddly specific, I have this issue with color negative film and a yellowish tint on the edges of film from the scanner light leaking obliquely through the sprocket holes into the image area being scanned, especially with certain films - like Fuji 160 in fact!

Whoa! Cool! This was not even on my radar! The dev and scan was done by Thefindlab.com, and they have done others for me w/ no issues, but those were different films.

What other films have you encountered this with? Just so I know not to use those if I want to include the sprocket holes.

Thanks!

This image was shot with a Horizon U500 pano, but also developed/scanned by thefindlab.
Different film - Fuji C200 - no yellowing. Also could have been a different person scanning it.

This camera occasionally did have light leaks, but they appeared as pale foggy vertical stripes, of neutral tint. Those light leaks frustrated me as I never would know when they would happen, but did several times a roll. Really sweet camera otherwise and I liked it more than my (sold) Widelux F8

FWIW while the sprocket strip identifies the film as S-200 (Superia 200?), on the box and cassette is says C200. Which leads me to believe it is the same film.

Agree with that. Heat fog done that to me before.

It seems to have been worst with Fuji 160 for whatever reason. Does it somewhat on any negative film, especially if it has some base fog (expired films). Portra seems to be okay for the most part when fresh.

Do you have a light table? If so put the negative on it and mask it off completely, then photograph it with a digital camera, and invert/color correct. Then you can check, and see if that is in fact the problem. I could be wrong.

BTW, that last image you posted above, I feel like there is indeed some orange/yellow cast on the top of the image.

I have a Photoshop Action designed to fix this with appropriate masking when it happens.

I'll have to do that when I get the negs back (the scanned images are downloaded)

I use two different sources for my dev/scanning needs - thefindlab and northcoastphoto. thefindlab scans panos with the film strip, while northcoast photo does not. The next batch I send in may go to northcoast to see how they compare.
