ESSENTIAL FILTERS FOR LANDSCAPES
Certain optical fi filters lters allow you to control the contrast of your black & white images ( see page 70), much the same way as you can digitally using colour channels and HSL ( Hue, Saturation and Luminance) adjustments ( see page 78). But there are a few optical filters whose effects cannot be easily replicated and are essential for landscapes:
GRADUATED NEUTRAL DENSITY When skies are bland or you want to make a brooding storm bolder, ND grads are key. They reduce the difference in brightness between the sky and land, balancing the exposure, the sky is also correct. For dramatic results that darken the sky try stronger density ND grads such as the 0.9ND or, to control a bright sky for a more balanced scene, a 0.6ND.
POLARISING FILTER Like a red filter, a polariser darkens blue skies making clouds ‘ pop’, increases contrast and clarity, as well as removing glare and reflections from water and shiny surfaces. It’s an incredibly useful filter to have in your kit bag.
NEUTRAL DENSITY FILTER ND filters allow you to increase the exposure so you can record movement in the landscape. Densities such as 0.6, 0.9 and 1.2ND are useful for blurring fast moving water, but extreme NDS allow you to create simple scenes using long exposures in daylight to capture motion.
