A friend of mine owns a Super8mm-print of Walt Disney's "Aristocats". It was made by Derann Film Services in the mid 90s, the film stock is AG 2S.

On this print (as well as on a "Pinocchio" copy from the same time and printed on the same film stock) in several scenes there is magenta/pink aura along the outlines of some of the chracters to be seen.

What is strange:

- these changes/this phenomen seem to be new (last 6 months)
- there are no signs of film treatment or other chemical problems on the film's surface to be seen
- films are stored at room temperatures of 18 - 20 degrees C.
- other films from the same period and on the same film stock show no sign of this phenomenon

Did anyone else encounter this effect?

Does anyone else have prints of "Aristocats" or "Pinocchio" on this film stock and from the same period and source.

Derann staff are informed and a reel of that film will be delivered to them in the next days/weeks. So far, they have no explanation for the effect and have never encountered anything similar.

Here a picture made from the screen:

This looks like something that happened during printing. On the negative the arm would be clear while the door would be dark. When light passes through the negative it looks like it spilled over the arm to give that 'aura' look. Although I haven't seen or noticed something like that, this is only an educated guess.

I agree with Larry. It looks like the effect you would get with dirty optics especially dust on a mirror.

Years a go when I ran some colour printers for Ilford we would see this effect on photographic prints if the silver surfaced mirrors had dust on them.

Its the dust scattering the light about. As Larry says the black arm would be letting the most light through the neg so that is where you would see the most scatter.

Thank you,Larry and Kevin

The strange thing is that this effect only recently surfaced. Before that the print was clean and this phenomen was not there. Could it be that the magenta part of the colour is not stable and just leeks out?

I might have to go with Langner on this ...

I have Woody and Chilly Willy cartoons from the early 80's that have this same phenomena, though they are on the regretable Eastman, and I'm sure that his Aristocrats is on L.P.P., so could it be a problem from the film lab, as the only place the fading seems to happen on my Woody's is with extreme blacks, which have a slight reddish/magenta halo at time? the other colors do not seem to be affected.
