This B+W 67mm Soft Pro Basic Filter utilizes small mini-lenslets on a precisely plano-parallel glass disc to create a soft overlay of unsharpness on sharp images. The scattered light produces hazy, diffuse halos, adding depth to shadows and creating a shimmering aura around highlights. This filter is perfect for portrait photography and can also be used to soften contrast and light fringes in backlight situations for a gentle and romantic effect.
