rponiarski: Please note, I have had a couple of complaints that some of the photos are not taken at night. Cruise Night, at least around me, start in the late afternoon, say 5 PM and then last until about 9 PM, so for a while it is light. You can see that in the sample photo I uploaded. So there is no need to the shots to be taken at night and I am sorry if anyone was confused about the challenge.
OK - but if a picture is not clearly indicating it is night, then pls. take into consideration exif data and disqualify all pictures which were taken before, say 5, 4 or 3 p.m. (is 3 p.m. "night-enough"?)
There must be some boundary if it is to be a challenge with "night" in the subject!
