This is fun, I shot 35mm for over 15 years before I found a 120 Pocket Autographic Kodak just like the OP, I thought it would be a cheap investment for $20 at a yard sale and a fun foray into MF.... THOUSANDS of dollars later in chemistry, new cameras, fridge full of film ... man if I only knew... but it's fun to see the me just 1 year ago...I had the same exact question and was SO AFRAID of the paper having light through it ... don't worry young paduan
