Re: Maco IR films

[Magnus Slayde <magnus13@xxxxxxxxxx>]

I shot a roll of KODAK HIE on sunday afternoon, full sun, vary few clouds in
the sky, I stacked a red#25a,Yellow#8, and A linear polarizer together, and
figure after all that a film speed of asa100, I developed the KODAK HIE in
RODINAL 1:50 at 68 deg. F. for 18 minutes, I have'nt printed the negs yet,
but the contrast looks good, the grain will probably be a bit large though,
I usually prefer to use d-76+orthrazite, or ILFOTEC-HC
