Those Darn Black Specks!
If you use a camera with interchangeable lenses, you get to enjoy a lot of features that owners of compacts don’t... but you also encounter a special problem: dust. Unlike compacts, DSLRs and mirrorless cameras aren’t airtight. Because of this, dust and impurities sometimes reach the lens. But don’t worry! Any camera repair shop out there can get the dust off your sensor, and as for dust spots in your photos, you can remove these in Zoner Photo Studio.
