If you regularly shoot in dusty or sandy environments, here’s a handy tip for keeping your camera clean: create a simple cleaning brush that attaches to your camera bag. Digital Camera World writes,
You’ll never bag a great photo with dirty lenses and dusty gear, so keeping your camera and lenses clean and protected is crucial. The front line of defence against dirt and grime is constant cleaning. This isn’t easy if you have to carry around cans of compressed air, blower brushes, fluids and other bulky equipment. Professionals actually tend to use ordinary paintbrushes for camera and lens cleaning, so save yourself money and space [by] making a handy cleaning brush that clips onto your belt.
