with this in mind and the hundreds of other photo contests like it, i asked myself so what's a good and fair photo competition? fair to both the organizer and participants?

it seems like there's more one sided challenges than there are where both organizer and photographer will benefit. why do organizers have this rationale that what was submitted will be theirs even if it loses? perhaps its just to cover up the expense of the event or just plain old greed?

can you post links here of fair competitions(finished and on going) as an example?
