There are a few rules;
A) Photographs must be shot on/after the theme was announced on 5th October 2012
B) Photographs should be posted in this thread before it is closed (see provisional date above)
C) If a person enters more than one picture, each should be in a separate post (if they're similar, this may dilute your votes)
D) Since many entrants do this; it seems only fair that everyone entering should cast votes for each other's efforts
E) Any votes cast for your own photograph(s) will be ignored
Voting;
When announced, voting (open to any member) will be by Private Message (PM) to Dave Humphries, over a period of three days or so. This will ask you to state your favourite three photographs in '1st, 2nd, 3rd' order by "V number" reference.
(of language) Open to more than one interpretation; having a double meaning.
Unclear or inexact because a choice between alternatives has not been made.
