So my sister was messing around with my camera when I wasn't around and managed to take the lens off my 5D and enable sensor cleaning mode in the space of 10 mins. Then she got bored and left it, therefore my sensor is in pretty bad shape. I'd like to know what to do next please guys, I hope its ok.
Heres a shot of a white ceiling (hence the change in white to the left of the frame), f16, 97mm, ISO 1600.
