1. The entries must be taken with OPPO devices, including all models of OPPO phones and OnePlus phones.

2. Only photos in JPG, JPEG, PNG, DNG, HEIC, and HEIF format are accepted. The submission should not be smaller than 1000 pixels in width, and the size of a single photo should be larger than 1M and not exceed 20M.

3. Each user can only submit 15 entries at most per category (nine categories total, ten if you are 18-24 at the time of entry). A single photo/group of photos (no more than 9) is considered one entry, and uploading single images with repeated or overly similar content is not allowed. The entrants are allowed to submit the same photo to different categories, but each submission will be counted as one entry.

4. The photos should not be altered in any desktop image processing program such as Photoshop and Lightroom. Moderate post-processing on the photos is permissible, such as adjusting the brightness, contrast, white balance, saturation, etc. Composite images that change the original content of the photo are not acceptable. Complete EXIF data must be retained.
