Read full descriptionHide full description
Photo challenges every month: each month a topic will be published and participants have to upload their work. Test your imagination and ability as a photographer. When uploading a participation, simply choose from the gallery or from your mobile camera. The image metadata (if any) will then be automatically populated. You just have to fill in the title of the photo and if you want us to share your work on our social networks. The idea is that you upload a photo captured the current month, so you force yourself to go out, use your camera, and capture something fresh. But of course, you can upload what you want. You can modify or delete your participation at any time, as well as modify the details of the photo: title, description, metadata... You will also be able to comment on other images participating in the different monthly photography challenges. As soon as the contest ends, 12px.app team will review all the photographs and make a selection of the best ones. To see the winners, simply navigate the app to the "Previous" section, where all past challenges will appear. In the Profile section you can see all your uploaded photos, as well as add or delete access methods to your account.
