BSA234: Polarised Filters 



I was wondering through the rose gardens at Queen’s Park today taking pictures on my phone (most of which can out quite well actually – I’ve added some for proof) and I was looking at some thinking they were quite dull and wouldn’t it be nice if they weren’t. Turns out that exactly what polarising filters can do for your camera according to these useful articles I found (1 and 2). Polarising filters increase the exposure and contrast so the colours in the pictures you take look far more vibrant which is particularly useful for outdoor photography. They also reduce the glare on water or glass (non-metallic surfaces, according to those articles). This glare reduction, when photographing water, makes what is under the surface much clearer in the image so, I assume, would be excellent if you were taking pictures of something such as fish in a pond.

Polarised filters are also used in sunglasses which explains why the world sometimes looks far more vibrant and beautiful when you are wearing your sunnies!



The images below I took on my phone. I feel they would have benefited from a polarised filter as it would have made the colours pop more and brought a little more life to them, especially the middle one.

  1. Thanks, Yohanna. Please note that polarisers increase colour saturation and contrast. They don’t actually increase exposure – they actually cut back on the amount of light coming into the lens.
