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.
