How To Detect And Remove Dust From The Sensor Of Our Reflex
Dust on the sensor is something inevitable and unfortunately, when present, appears on the photos, which forces us to figure out how to locate and remove.
You have probably already seen some dots on your pictures: the small dots that blacks tend to be sharper when using very narrow opening. To see if it is actually dust or dirt on the sensor, we can do a simple experiment: put your camera in manual mode, you restrict the opening down to values ??of f / 16-22 (or the minimum available) and set the shutter speed to approximately 1 second.
