Why do you wear sunglasses? Well, they help you see better in intense light, protect your eyes from harmful UV rays, wind, dust and also reduce glare.
Camera lens filters also serve a similar purpose – they protect your lenses from potential damage, alter the characteristics of light passing through the lens, enhance colours, minimize reflections and add special effects to your image. Landscape photographers heavily rely on various filters to produce some beautiful effects.
Understanding how filters work will help give in creating that magical shot you’ve been looking for. Check out this handy infographic The Photography Filters Cheat Sheet created by The Studio at zippi.uk.co.
