Recently i have tried my hand at photographing the effect when oil is added to water, and the results can be amazing. All you need to start is a clear glass container, water, cooking oil and a backdrop - you could use colored card, wrapping paper, anything you like really. The main thing is to experiment and have fun.
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.
