I set my camera by default to "CC BY-NC-SA 3.0 DE" and it write it to the exif part of the picture. But i desite with this picture to release it under "CC BY-SA 4.0" as i had choosen in the licence selection. How can i fix it that it could stay in WC ? delete it - fix the exif data and upload it again - or is there a more smooth way to do it? Thanx for your advice!
