Tips for uploading a poster

Please ensure you enter the correct competition category using your centre or school's postcode
Please ensure only high resolution, high quality images are submitted
Image files should be in .JPG, .PDF or .PNG formats
Uploaded files are limited to 20MB
Original posters can either be scanned or photographed
Remember if taking a photo, please ensure a clear, non-blurred image is taken. Keep these tips in mind:
- ensure good lighting to avoid shadows
- make sure the poster fills the entire screen - an overhead shot, taken directly above the poster, is often the best option
- ensure the photo matches the orientation of the poster – if the poster is in landscape format, take the photo horizontally. If it’s in portrait format, take the photo vertically
- avoid using flash, as it can cause glare
- if the photo is taken from a distance, crop the image so only the poster is visible (no background or surrounding surfaces)
