I added a copyright to it alright as I was led to believe there was unauthorised use of another image on flickr. I didn’t touch the sharpness though only added a copyright layer. Would this have made a difference to the sharpness? I still have the original un-copyrighted image and I can’t really see a difference to be honest.
EDIT: I think you might be mixing it up with the first darker image as that was much much sharper.
