Hi guys. I'm on a weekend break in Matlock. I woke up this morning to a beautiful sunrise over the valley. Got my camera, ran outside, looked through the viewfinder and there was two large spots to the top left corner. I changed the lens but its still there (on the LCD screen too). Now I've heard that the sensor can get dirty but I've only had the camera one month. Surely it can't get that dirty in a month. I went on the Internet and every website tells me I have to take it to a shop to get it cleaned. I can't do that all the time. Please help.
