Hi There, There seems to be something wrong with my images where the colours look weird and I can't seem to have any control over them. I'm wondering if this is my settings in my camera, or my computer or computer program. I just can't work it out. This photo I have just lightened it a bit from the raw file. I really hope you can help as I'm wondering if my camera is past it? My other lenses are worse. Many thanks Lucy 🙂
