The blue hour is this short period of time of twilight ending just before the golden hour starts before sunrise, or twilight starting just after the golden hour ends after sunset. It gives very interesting blue hues. Your entry can be any subject taken at the blue hour time. The only restriction I would add is that images should be in colour only. Enjoy!
Every photo submitted will be available for the crowd to rate once the submissions period has ended. You can see all the images uploaded to a contest, but will need to rate them to see how they’re ranked once the rating period begins.
Some contests on Photocrowd also have a judge. After the submission period closes the judge chooses their favourite images and writes some image reviews. The crowd and judge results will be announced on the same day.
