I pre-wrap all my 35mm rolls w/ a piece of masking tape. After I expose the final frame of the roll, I mark the piece of tape with the date and camera used. During development, I transfer the tape to the Patterson tank and later to the negative clip while drying. Once I cut the negatives, I move the tape to the storage sleeve. In the notes section of the sleeve, I also note developer type, dilution, time and temperature.
