Thanks for the tips, Klaus.

Rangefinder duly noted,

I have a changing bag but was told that it wasn't needed for the Konica 
film,

I shot the Konica film at 5.6/60th as per the poop sheet,

Yes, I need to look into getting a very dark red filter,

I used the infrared index on the lens, is that what you mean?

Thanks for showing me your infrared photos, I'll try to see if I can do 
as well.

Jim
