I usually dive with a regular group(s) of diving friends, when everybody is easy going and there are generally no issues when it comes to underwater etiquette.
However I was on a dive trip recently in Lembeh and I was on the dive boat with strangers and there were some issues. One guy confronted another who unwittingly hit his subject (poor frogfish) with his fin. Another guy confronted another group of guys taking too many photos with strobe of a single subject. ..etc
Also i just read a thread, where a "pro" photographer, Rod Klein, prodded another diver with a pointer to prevent stirring up the silt. Leaving her with a bruise. Link to thread with photos..

So I was wondering if someone could point out a good write up on etiquette as Im not keen on ruining my dives with this type of an experience. Thanks.
