Slovakian company 84.5mm has announced a new series of reversed neutral density filters. These special ND grads have been designed specifically for shooting landscapes during the so-called golden hour, when the sun is very close to the horizon. The filters are darkest in the middle, getting gradually lighter toward the top - as opposed to a standard graduated neutral density filter, which has its darkest part at the top. Available in two densities, medium and strong, these reverse ND grads come in two sizes: 84x100mm and 84x150mm. The standard price is €36.50 but the first 50 customers who purchase a reverse ND grad from 84.5mm's e-shop are entitled to a €4 discount.
