Developing How should I develop old 120 film that has no indication of color, ISO, or process?
My Grandpa found an old 120 film in his Flexaret camera and asked me to develop it. The problem is that on the film is no text and I have no idea about the type (color or b&w?), ISO or what process I should use. He told me that the film is maybe 30 - 35 years old. If anyone can help me I will be grateful.
