How about putting a Zeiss Softar (or a poor man's version avialable
from other manufacturers) in front of our lens?

Halo effects have nothing to do with infrared effects (such as
white foliage). They are just 'incidentally' both separate features
of Kodak's HIE. It would give us more freedom if we could control
each of the effects separately depending on the subject.

Sensitivity to the infrared part of the spectrum is a feature of
the emulsion, i.e. the film. Halo effects should be limited to be
a feature of the optical system, i.e. the lens!

Just my personal point of view ...
