The Tiffen Filter Wheel 3 Low Contrast 1/2 Glass Filter works by spreading light from the highlights to the shadowed and darker areas, leaving the bright areas of the image bright. The dark areas become lighter, enabling you to see more detail in the shadow areas. As there is no f-stop compensation, you will not overexpose any portion of the image.
An old house with a covered porch? A tree shaded country road? Your model is in the shade yet the surrounding venue is highlight-heavy... How can you save the image without blowing out your highlights?... Open the shadows! Hold the highlights! Tiffen Low Contrast filters are the answer!
