Got my bulk roll of unperforated Kodak Gen 2 (Portra 160NC) today. Loaded a test section (not even a full roll) into a 126 cartridge and put it in the Kodak Instamatic 500 for some tests. Shot through it, then warmed up the Tetenal 1L kit and souped it. Still drying but the color looks good! I will load another cartridge and take some better shots soon. 100' should keep me in business for a while, hopefully the Tetenal will last... then I've got a second kit to mix.
