I think it's about a model, or a porn star or actress who's been photographed naked. Jim has been with her and knows her personally, rather than just knowing what she is infamous for. He sees her going about her daily life, "free from disguise," and he also sees her fix her hair to appear on camera, and let them photograph her soul, or most intimate parts. "Memorize your alleys on an endless roll," is the line that gives it away -- it's a roll of film, endlessly making records of all her body's alleys which Jim may or may not have known in person.
