That's Odd. What caused this white line?

No other images affected. MP, 28 Cron Asph, AgfaVista 200. The lens possibly had a neutral density filter on it but I don't think that is the cause. I've not looked at the condition of the negative, but do you think something other than physical damage could be the cause?

A hair? Not at the capture stage in the camera because that would cause a black mark, but if a hair or strand of something got onto the negative before or during the scanning stage that would show as white.

Thanks Steve.

If it's on the negative then it must be flare.

[Stealth3kpl]

I've been too lazy to dig out the neg but will see if I can find time to look tonight.

Well, I'm rather surprised to see the line is in the image of the negative. I wonder what it could be. I use the 12589 hood on the 28/2 Asph. Do you think it could be a reflection from the straight edge of that hood?

The line has a gentle and regular curve, points to a reflection/flare effect to me. Hard to tell but there are pools of that strong sun around where you stood you could have just had some hitting the hood or even the lens thread. It is black but quite reflective if you look and that front element is not what you would call recessed.

The 12589 is from the F1.4 35mm Asph isn't it? Does it not have a metal spring "thing" inside, could that cause a reflection? I have the ridiculous in price 12451, second actually the first fell apart, and no 12589 at present I presume, up to now, you preferred the 12589 being smaller but perhaps less effective on the 28mm than the 35mm?

Hello Pete,

 

I also noticed the curve in the line that Chris noted in the Post just above.

 

The curve seems to be a symetery of the black wire/line that begins in the upper right hand corner of the photo & follows along & meets with the white line we are writing about in the ceiling of the upstairs balcony across the street.

 

It is interesting that inside the angle created where the 2 lines meet there appears to be a higher degree of flare.

 

An enlargement of the spot at/around the meeting point might be useful.

 

Best Regards,

 

Michael

Yes, the 12589 is less effective but easier to pack in my bag. I use hoods more for protection of the front element/filter than for shelter from flare. Flare doesn't usually bother me, in fact I usually like it, but flare like this would render a decent image useless. I'm lucky this isn't a very interesting image anyway.

Thanks for your input Michael. I don't know if this is of help but I'll give it a go.

Hello Pete,

 

It certainly looks like there is something inside that angle.

 

The area inside the white line & the black line becomes more "flarey" between the traffic lite/crossing sign & where it meets the other line.

 

Best Regards,

It's interesting that the general direction of the line is parallel to that of the shadows.

Hello Pete,

 

It is sort of like there is a sheet of something flexible & transparent which is also square/rectangular that is in the image path.

 

See the flare in both of the glass doors in the 2 balconies at the top where the white & black lines meet.

 

Best Regards,

Where the two lines intersect the overhead wire changes direction slightly, down, seen best in the darker copy. I think that is it, flare from that wire, very interesting and probably not easily reproduced.

Hello Chris,

 

That would make things a combination of the flare you spoke of with a reflection from the wire down to the street as per the 1st photo.

 

That seems like it might be possible because a significant portion of the black wire is reflecting the white of the sun in the 1st photo.

 

Best Regards,

Perhaps that line should be straight and has a gentle curve from the lens, whisper the word distortion ? Or perhaps the wire just sags !!

 

I suspect if sufficiently mathematical competent using the shadows the angle of the sun could be calculated and the angle of the wire to white line it could be proved. 

Well they did work out the timing for Ansel Adams Moonrise : 4:49:20 p.m. on November 1, 1941

Hello Chris,

 

It appears to me that this is an instance of a wire sagging. There are a lot of flat straight lines in this photo.

 

Best Regards,

Not unlike the effect that the David Warner character noticed in The Omen.   Perhaps a bit of a close shave for the two people in the middle of the photograph next time they find themselves in a churchyard during a storm?
