I've only got halos on Konica on film that has been overexposed by about 2
stops.

Another odd thing about the Maco IR, there seems to be a gelatine coating on
the
base side of  the 35mm film. I found this out when I notices that  what I
though was
damaged emulsion, only it was on the base side. This is a first for me.Just
developed
my first tests of the 4x5. It has a matt finish on both sides when it is
dry.
Only way to know which side is up, is to look at the edge notch. I found a
few pinholes too.
