Clean Sensor
Image of my sensor just after a good cleaning (small spots are left, but it's not a problem for usual images). The darker parts on the corner are due to vignetting and not some kind of sensor dirt. This is perfectly OK.
To obtain such an image:
- Go to maximum aperture (f.22 or f.30)
- Adjust speed and take a white surface shot (long exposure is not a problem, if you move the camera when taking the image it avoid confusion between the white surface dirt and sensor dirt).
- Apply an auto-level on the shot, here is the result.
The the sensor before cleaning.
