Odd marks on film?

[barnacle]

Just puzzled as to what the following marks might be - here's the whole image (scaled to a sane size):



The most obvious faults are the two white stripes - just above the window, and on the head on the left lintel.



There are some solid black areas on the tiles:



And one area that's neither one nor the other:



These are not scanning errors (though there is dust on the scan - a very rough and ready scan) - they're in the negative. The white stripes are there in the silver; the black bits don't look like missing emulsion, and I have no idea what's going on in the last one - it's there on the neg.

Any thoughts?

What film?

[barnacle]

Adox CHS 50 - a couple of years out of date. But check the 'show your churches' thread in the pictures section for three more from the same batch, same place, same day, same developing tank.

Adox, There's your sign.

White marks sure look like hair/fuzz to me at time of negative exposure. Not sure about the others if they're also on the negative.

[barnacle]

Hair on the negatives would show black on the final image, no?

It could be static electricity !
The black areas might be a precipitate during the development.
The grey area, could it be in the subject ?

[Paul Metcalf]

yeah, sorry brain fart on my part. Was thinking negative when looking at images.

[barnacle]

No worries, Paul! We've all done it...

Thalmees, I don't *think* the grey area was there in the subject, but it's possible. Static... well, I did wonder about that but I would have expected a more 'feathery' line - though I admit I have never seen static on a film before, and it *was* a new box of film, wrapped in plastic, in a nylon changing bag, on a dry winter day - classic opportunities for static to be generated. I can't see a precipitate from the development given (a) that it was continuous development, and (b) three others in the same batch show no sign of it.

I'm leaning to a film fault of some type.

Hello Neil,
Static usually choose the best negative, but fortunately it does not know yet the best place on the negative. I'm talking about my static. Yours, looks it does know where to hit !!!
Why you do not elaborate on film(type/size) and processing ?
Lots of photographers around(LFPF) are so kind to share their experiences on this topic.
