I finally got a reply back from Fuji why 50% of my photos didn't come out and all but 3 had this bad red tint on them,
They said,
The film has been exposed to a low level light leak (Fogging) when the
light has exposed the film there has been a reflection of something with
that kind of mottle which has exposed onto the film. The grid lines could
be from the backing plate which keeps the film flat in a lot of cameras.
Definitely light fogging though just how it has occurred. One big point if
the camera has been leaking light. If there are two frames or more taken in
quick succession and these aren't affected too badly and one or more which
has been taken and been in the camera for a period of time before winding
on and this one is fogged badly proves the camera.
Light leak is usually due to the casing being compromised, ie dropped or
damaged and light has managed to get into the camera case prematurely
exposing the film. Without examining the casing can't really comment. Out
of a gesture of good will we can send you two cameras as replacement.
Please provide us your full UK address for these replacements to be sent
too.
So, I have 2 new cameras. When is the next challenge
