overexposed/ overdeveloped stripe on the negs

[desienna]

<p>hi to all,</p>

<p>i've just been developing a batch of bw films from a trip abroad<br>

and i found on various negs, quiet randomly, a darker 'line' on the upper side (up in the sky),<br>

it appear darker on the negs , therefore is whiter when scanned,<br>

so i've been considering either overdevelopment or overexposure,</p>

<p>re overdevelopment i found it strange because if the film is overexposed<br>

it should be all of it , not just the upper side,<br>

(i'm talking about 1 mm of the actual neg, not much)</p>

<p>it's not big deal because it's barely nothing, but i do want to understand why this is happening,</p>

<p>it shouldn't be fogging or light leaks because it would be the opposite,<br>

(whiter on the neg , darker where scanned),</p>

<p>and i don't think it's something mechanical about the camera (mamiya 7 II),<br>

because i did also a batch of colour slides and they all look fine,</p>

<p>any suggestions and advice is very very welcome,</p>

<p>cheers,</p>

<p>Luca</p><div></div>

<p>I sometimes would get this. I figure it was the wine I inadvertently would pour in with the developer.<br /> Seriously, do you think the developing solution had the correct amount to cover the entire height of the film? Even agitation won't cover up for a mistaken amount of developer that should be used to cover the entire negatives.<br /> Just a thought.</p>

<p>Not enough developer in the tank.</p>

<p>Darker on the neg means extra exposure has been made there either in the camera or wound not tightly enough or somewhere.</p>

<p>A clear or less dense area on the negative could mean not enough developer in the tank.</p>
