Guys, this is all getting a little serious - can't we all just get along!!
Cochise I agree with you, it is just a bit of fun, and should be viewed that way. I guess it is hard to have too many hard and fast rules, as I know Deb wants to allow flexibility to encourage as many people to enter as possible.
As you said, one of the reasons for the "discussion" thread is to allow people to question pics as well as techniques used.
Personally, I think as it is a photo comp, the entrants should've taken the pics, otherwise I guess it does become open to photopass pics etc etc. I would imagine that others feel this way, and as such photos with the poster in them, generally do not fare very well in the voting.
That having been said, as Tron said, if you take hundreds of pics it is hard to know who took 'em, so you have to allow a certain amount of leeway, but, as Joh said, if you're in it, it is unlikely you took it!
I take thousands of pics, and if I am in one that I used a tripod and timer for I will always know it.
Not sure what I am adding or subtracting from the discussion, but thought I'd say it anyway
Like I said it is just a bit of fun and an excuse to show-off your photos, and hope we would all view that way.
