I reckon it's happened in camera too. To get a better handle on the problem I inverted the image of the negative strip at http://www.procaptura.com/~toralf/bilde.php?navn=neg and saw to my amazement that the grossly overexposed frame 18, as well as the better exposed but very flared frame 19 had the sun in the frame. Looking at the inverted (thus true toned) neg strip I can trace the path of the light from the sun as it travelled through the emulsion by means of 'light-piping', which is the same principle used by fibre-optics. This passage of fogging light would have continued all the while diminishing to nothing, except that a short way from its source it struck the architecture of the camera. The stainless steel pinch roller just beyond the edge of the pressure plate is the likely cause of the band across frame 17, which had already passed the film-gate on its way to the take-up spool. The partial band of fog across frame 19 would correspond to the limit of the film outside the velvet light trap of the cassette.
