Sample request Missions are focused on a physical product rather than a concept (like in a Generic mission). The brands provide you, the photographers with a product sample and a creative brief which is a description of what is specifically requested from the pictures or videos.
Once you have received the product, make sure to follow the brief and upload your best shots.
Top pics have a chance at winning a monetary prize set by the brand. Additionally, the brand may purchase photos at a usual rate out of all pictures submitted.
