B+W Polarizer Tip: Blue Sky

Photographs taken approximately rectangu-

lar to the direction of the sun achieve the

strongest intensification of a blue sky for a

more dramatic rendition of clouds.

Experiment with colors

Many transparent plastic materials, such as

plastic rulers and crumpled cellophane film

show interesting colors when placed be-

tween two polarizing filters or two polariz-

ing sheets. These colors change when the

polarizing filters (or sheets) are rotated in

relation to each other. This method can also

be used to visualize internal stresses in plas-

tic replicas of mechanical parts as patterns.

Decorative cabbage photographed without a lter

… and with stronger reds using a Redhancer

A polarizing lter makes the clouds

stand out, but on this very wide-angle lens

it cannot darken the sky evenly

With a warm tone polarizing lter, shadow

areas are rendered with the correct colors,

without the clouds taking on a reddish cast
