What went wrong on these negatives?

[sakebalboa]

These are scanned and inverted negatives ilford delta 3200, processed by dwaynes. These are the only three negatives that exhibit that weird casting along the top (or right in the third image). Was this a developing error? they seem to originate from the sprocket holes, i remember seeing something similar to this effect when i used to develop my own film and i happened to let some light in through the lid, but in this case it only effected three almost consecutive frames shot in partly cloudy daylight, the rest were overcast or indoor shots.

I really hope it has nothing to do with my camera 😱

whoops forgot to post the images

Your pictures aren't showing up.

 

[sakebalboa]

they should be showing up now...i hope

Looks like developer sticking in the sprocket holes to me.

I have not seen slanted streaks like this before, just straight ones... I'd think your guess about light exposure of one side of the roll is a reasonable one. Were these three images all at one end of the roll? See any similar evidence on the adjacent leader/trailer?

these were in the middle of the roll

ok i just took a look at the strips, i'll try and get a scan of them tomorrow, so it looks like starting from frame 0 to 15 there are black lines that come in and out along the top of the negative, its very thin, hairline to about half a cm in a wave pattern. the streaks are evident in the three frames which are frames 11, 12, and 14, frame 15 upon closer inspection shows the same thing. this was a shot taken indoors! after frame 15 the lines across the top disapear along with streaks.

Weird...

How did you agitate?

How did you agitate?

I didn't, i sent the film off to dwayne's for development.

When I did develop my own film, I agitated very well 😀

I've seen problems like this in developing before, and if that is the case it has nothing to do with the camera.
The usual explanation is overzealous agitation causing developer to flow differently near the sprocket holes than elsewhere on the film.
As Doug points out the streaks are usually straight inboard of the holes, but if the folks who developed the film for you used a type of tank that would be agitated differently, it could explain the curving streaks.
Anyone know what Jobo streaks would look like?

Sticking shutter curtain?

As you can see in the pictures, you have more density in the neg (less in the print) where there are sprocket holes. Common logic has it, that this is caused by to much agitation but things are bit more complicated than this. In effect, you do not want any kind of flow going favourably through the sprocket wholes.

The problem can be solved by less as well as more agitation. Vigorous agitation for short times and letting the tank sit untouched in between is one way to get rid of this problem. OTOH you will not see it with stand or semi-stand where you can find several kinds of unevenness and smudge if not well blanced but never this one.

It seems like an agitiation problem during the development stage.
