as in bright contrast landscapes. Sometimes it is also desirable to add color to
part of the photograph. For example, to add blue to only the sky.
Half colour, half clear with a graduated density transition for smooth blending
into the scene.
Using the right gradual blue filter will ensure that the image maintains a
natural appearance.
Their color gradually fades out so the boundary between the colored and
transparent sections will not become apparent even with the lens aperture
stopped down.
