Bugger you for asking that Kyrre
! Your guess as to the number of photos i took is pretty close. Of course some of the shots were more or less duplicates and others bracketed shots (same shot with a different f number or shutter speed) but even allowing for those, my success rate is still not very high, say 10 frames per roll, the failures being due to such factors as over-eagerness (not waiting for my strobes to recharge), poor composition (cutting off the tail end of fishes etc), poor focus (inability to get close enough to macro subjects because the frame got in the way), back-scatter due to myself or or other divers stirring up sediment etc etc. I like to think I'm gradually getting better, though.
