Re: Kodak HIE film in a 120 format?

[al <nissar@xxxxxxx>]

Going along with this thread i have purchased some Konica IR today,

I have an opaque ir filter and am willing to give it a try, whats a decent
ei for a bright sunny day, im going to be shooting in central park. Also
whatis the best way to develop it, 
AT home i have d76, Tmax, sprint film developers.


Any reccomended times and temps etc... would be appreciated 


thanks
