Here's one from the Lembeh trip (ie the most recent). A few seconds after I took this shot one of the other divers, having looked as much as she wanted, turned around and kicked away. The nudi was washed away and there was silt everywhere ... and it turned out this was a diver with 500+ dives ... unbelievable!
