You can get extreme flare with Konica IR 750. George is right, it is not
as extreme as the Kodak flare, but it is quite noticeable on the Konica.
Basically any film will flare around a bright highlight. The anti-halation
layer cuts the tendency, but it is still visible.
I've obtained the best flare using very bright tungsten studio lights. The
model has very pale skin, and I used a #25 wratten filter. I develop in
Rodinal 1:50 as George does as well. Expect to get very different exposure
indexes than anyone else. With my set up Konica IR runs at about ISO 100.
I will post some of the images to the IR gallery so you can see what I'm
talking about.
