Removing glare from reflective surfaces such as metal, glass and water is often an issue when trying to take photographs with a mobile phone camera and polarising filters are specifically designed to fix this problem.
A polariser lens is also effective on sunny days when you are shooting at a ninety-degree angle to the sun. This is because polarising lenses work to block vertical light waves that have the greatest glare and those vertical lightwaves are most intense when the sun is at a ninety degree angle to you. Using a polarising filter allows you to photograph subjects or scenery in the middle of the day capturing more pleasing saturated colours created by horizontal (as opposed to vertical) light waves.
Using a SnapLens polarising filter is easy. Simply place the lens over your phone’s camera and then rotate the lens until you see the desired amount of light in your photo. You’ll notice a crisp blue sky and the white objects such as clouds will “pop”.
Taking photos in bright sunlight at midday without a polariser lens will often leave your photographs looking washed out as the light is very harsh on the camera’s exposure. A polariser lens will help to prevent this. This is because the sun is directly over the top of you (at a ninety degree angle) no matter what direction you are facing to shoot your photograph.
There are remarkable results from using a polarising filter when shooting north or south in early morning or late afternoon light. In this situation, the sun is at a ninety-degree angle to you over your left or right shoulder as the case may be.
Polarising filters are also extremely useful on overcast days as vertical light on these days casts dull reflective glare on wet streets, waterfalls, cars, windows, wet foliage, streams and rivers. A polarising filter removes the drab gray glare leaving you with a stunning photograph.
These photos were taken with my Samsung Galaxy S5 facing north in the late afternoon at the King George River in the Kimberley. The photo on the left is shot without a polariser lens and the glare detracted from capturing the spectacular scenery. Using my SnapLens Wide-Angle Polariser Pro lens attached to my phone I shot the photo below which captured the colours perfectly
