The importance of keeping a clean sensor

For a few years, a clean sensor didn’t actually matter to me. Using wide-open f/stops, most grime is completely blurred out. Then came this year, and I started to use much smaller, finer f/stops. In just a few months, I’m far more experienced at cleaning a sensor.  Have to – otherwise I’m spending huge amounts of time fixing photos in photoshop.

Take the photo to the right.  By using a small f/stop, I was able to get everything in focus.  But this includes even things on the sensor itself!  After merging into a single image, I ended up with more than 30 individual edits to remove specs.  And that was clean, compared to just a few weeks ago.

In this case, the dirt came from camping.  Dirty, messy camping.  Gets everywhere, and I sleep with the camera in my tent.  Disturbing?  Maybe.  But I’m not so disturbed that I’m carrying a sensor cleaner with me everywhere!
