First roll of black & white photos with Pentax Spotmatic F

Got my first film of b&w processed (taken by my pentax spotmatic f), realized that for shooting in black & white I would have to compensate for my shots or used a zoning system. Some shots I messed up so bad, some I got fairly right. Need to practice even more =)
