Figure 17-7 Polarizing fi lter outdoors. These illustrations show how a polarizing fi lter can

the haze and bluish cast in the middle and background areas. The contrast is dramatically
improved in those areas. (Photos by Ernst Wildi.)
Figure 17-8 Polarizing fi lter. A polarizing fi lter on the lens eliminated practically all refl ections
on the store window by photographing the window from an angle of about 40 degrees and
not head on. (Photo by Ernst Wildi.)
