Help: film exposed -/- 3 stops

[martinola]

I suppose you're probably right. The edge markings just looked a little thin and made me think "exhausted developer".

 

[ekkybedmond]

By edge markings, y'all mean the Portra 400 ect text , if so, I've posted digi photo's of the negs, so they might be a bit overexposed...


or do you mean something else ?

Yes - also known as the film rebate.
Is there any chance you had accidentally dialed in a couple of stops of exposure compensation on the camera?

 

[ekkybedmond]

Don't think I have. I usually do NOT check for compensation, as I usually (...) return to zero after I compensate for some reason. And NEVER more than 1 stop.

Still the possibility that the film was 'off' then ?

Possibly but the fact that one frame from which there is an OK print and one frame which as a negative looks as near OK as makes little difference, suggests that the classic sign of an "off" film which is that probably all frames will be "off," is not conclusive.

Try a fresh film within its expiry date and do what I suggested. If the amount of sky does not underexpose the negative at box speed
then maybe there is no reason to doubt the effect of a normal amount of sky on exposure but do test the meter's weighting by checking the difference between no or almost no sky in a scene and then up to maybe half sky which is often the case in landscape type photos. If the meter's reading increases the shutter speed by a stop compared to no or almost no sky then you need to take this into account when taking such a scene

Hi guys

so I got a fresh testroll in my EOS 1V (like the 'bad'film) and it developed fine.

An older roll of Royal Supra , shot with my 1N to make double sure, developed like it was off, over the date, no too bad for portraits, but not for most other things

Negs should arrive within a week.

 

[pentaxuser]

In some ways it is beginning to look as if the film in question was "off" but strangely only certain frames?Photos of the negs when they arrive will be useful. The key comparison is between the "dodgy" neg of which you have a photo and a "good" neg from this latest batch whichhas about the same percentage of sky. On the surface the expired film should have been fine, give what you said about it but such things are possible. By the way what did your test of the meter changes when you increased the percentage of sky reveal? You can of course perform these tests without any film.

Test of little of more sky in the frame, resulted in only 1/2 stop difference

Does a "little more" mean close to or as near as damn it the same amount of sky as there was in the two underexposed negs and this resulted in only a half stop difference? Sorry if this appears to a question session from Hercule Poirot but I just want to be sure your half a stop is a comparison of like with like. Certainly if it is only half a stop in a like for like comparison then fresh colour film should cope with half a stop under quite easily.

If you confirm that this was the case then it looks even more likely that the suspect film was indeed suspect
