A photo of any type, any scene or anywhere just needs one specific thing in the photo. A light-bulb. The light-bulb must be the main focus of the photo. The light-bulb could be anywhere as long as it's the main focus.
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.
