Greenhouses have a history dating back hundreds of years, and have enabled the production of food that would otherwise not have been possible in that place, or at that time of year. They came into their own during the Victorian era, and range from small cold frames for growing vegetables, through the greenhouses seen in many back gardens, to the vast palm houses that were constructed in many public gardens and parks. Nowadays they also include impressive geodesic domes such as the Eden Project in Cornwall, UK, and the Climatron at the Missouri Botanical Garden in St Louis.
This Premium Contest is worth 1.5x the standard points towards your Leaderboard ranking. It’s Expert-judged AND crowd-rated, with your score from each combined. Find out more about ranking points here. Our Experts are some of the world’s finest photographers, who select the best images, and provide valuable feedback to help you improve.
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.
