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!
