Kodak Tri-X 400 is a medium-speed black-and-white film that is a great all around choice for many kinds of shooting. From casual snapshots to street photography, event work, and portraiture, Tri-X lends a classic contrasty film aesthetic to any subject. Many photographers love Tri-X for its prominent grain and its ability to easily take push processing to 800 or 1600. 
 
Each roll of 35mm Tri-X 400 has 36 exposures.
