Had a lovely holiday with some friends, I was the designated photographer so I sent all of the photos to everyone afterwards and told them to send the ones back they want uploaded to social media. All was fine however one friend sent back a picture and on closer inspection I would feel more comfortable photoshopping part of it. I don't want to upset my friend so I was thinking of just doing it without telling her but then I think if she looks at it compared to the original and she notices then she will be offended. Would it be unreasonable to just edit it without telling her?
