To improve your landscape photography, a polarising filter is one of the first camera accessories you should invest in. It works by filtering out light that polarises at a 90-degree angle to the camera lens, thereby reducing the glare of reflections from bodies of water and other shiny surfaces in landscapes. A polarising filter also makes skies appear to be a deeper, richer blue and darkens shadows. Although factory-made polarising filters can be expensive, you can make your own out of an old filter attachment and any number of household objects.

Things you need
- Filter attachment
- Polarised material
- Box cutter or other sharp implement
Obtain a filter attachment that fits on your camera, either by buying a special empty attachment, repurposing an old or damaged filter or making your own out of a can or even a cardboard tube.
Trace the outline of your lens attachment onto the polarising material.
Cut the shape of the filter out of the polarising material, making sure the cutout is about a quarter-inch longer in diameter than the actual filter attachment.
If the edges of the cutout are sharp, sand them down until they are smooth.
Glue the cutout to your filter mount. Clamp it under a book or other heavy object if desired. Let the cutout dry completely before using it.
Tips and warnings
- You can purchase polarising film from science or optics retailers, or you can use the lenses from 3-D glasses or polarised sunglasses. An LCD computer screen will also work.
