No Elias, it's the lower roller reflection, when the
light enters into the camera for the exposure, due to
some reason and for some cameras the light reaches the
lower roller projecting the reflection for the next
frame, since the image is upside, the brightest image
part is down and the darkest part up (for most cases),
the roller receiving the excessive light is the lower
roller, the light comes from the brightest part of the
image being exposed reaching the lower roller that
projects this reflection to the fram waiting to be
exposed, upper roller has nothing to do.
We discussed this issue along two years writing
thousands and thousands of messages in other forum, we
also had Claus Prochnow, Todd Belcher, Dieter Paepke
from Dusseldorf opinions, however their explanations
were not enough and exact about the problem, Prochnow
finally said it needed a camera with the problem to
overhaul it, but he was ill and could not do the work.
Other users having cameras with the roller reflection
issue had partial success filling the lower gap,
anyway the problem did no disappear. As I wrote this
morning, I and others never had the problem, anyway I
could obtain a roller reflection with my C
overexposing very much using F 4 and F 2.8, the 3.5F
under similar conditions did not show the roller
reflection.-
