I have seen grown men shiver and quake in the shoes at the thought of cleaning the sensor on their DSLR by themselves. The sheer anxiety of sticking something into your expensive camera body has left many people with the only option for dust removal being a stop at a camera shop or repair center for a cleaning. In this article we will look at how to clean your camera’s sensor the safe and easy way and dispel some myths around the black art of sensor cleaning.

During a wedding shoot one day I noticed that my flash was only firing occasionally. After the initial panic, I quickly figured out that if I held the flash with a little counter-clockwise tension, then the flash worked fine. At the first break, I tried my backup camera and it was doing the same thing. When I got home, I checked it against my daughter’s 20D and it worked fine, and it also seemed that the hot shoe on my cameras was loose compared to hers.Another symptom of this is that the flash will switch from E-TTL mode into TTL mode and the exposure will usually be very overexposed.
