I thought I would spend a little bit of time today cleaning the splodge on the sensor of my DSLR, there are a couple of methods to do this, one is to buy some sensor swabs and some sensor cleaning fluid and soak the swab then run it over the sensor! My preferred choice is to lift the mirror and blow the sensor with my rocket air chamber which is free of charge.
Anyway after I had cleaned the sensor and the mirror and the lenses, I proceeded to take some pictures of the blue sky with the lens fully open (best way to check for bugs and splats on your sensor), much to my surprise it was clean again.
My advice is to clean your sensor about once a month and make sure your lenses are cleaned every time you have been out taking piccies 🙂
