This is not something you would normally do: leaving streaks on a sensor after a “wet” clean. It happened to me and yesterday I did a proper clean, getting rid of all the streaks and other dirt. Afterwards I was thinking about the influence of a dirty sensor.
I came to the conclusion that a dirty sensor will influence exposure, colour rendition, saturation, focus and probably anything having to do with the quality of the captured image.
I am not sure if I came to the wrong conclusion or not, and I would like to hear from you people what your experience is.
How important is it to keep the sensor of your camera perfectly clean?
