Recalibrate Sensor for 40D
Jun 4, 2009

I was talking to someone who told me there is a way to recalibrate (possible wrong term) the sensor of my 40D. It involved putting the camera cap back on and going into bulb mode and holding the shutter open for a second. Has anyone else heard this? This was suppose to get better noise reduction and improve IQ.

Thanks
