Pro’s Killer Kit #01 Circular polariser
Charlie says… A circular polariser is the only filter that’s all but impossible to replicate in Photoshop, so it’s a must-have accessory for any aspiring landscape photographer. They’re typically used to darken blue skies, but they will have an effect on something, somewhere in the scene, pretty much all the time – even if it’s just subduing the reflections from my head! As such, it’s almost always worth holding one up to your eye, and turning it back and forth: once you’ve evaluated the effect it’s having on the sky, be sure to look at how it affects the land, too. It doesn’t have to be at 90 degrees to the direction of the sun to have an effect either. Just watch out for any effect altering across the frame when shooting at wide angles.
