Let your camera develop your dreams for you !
COKIN Dreams Filters are small circular lenses which create a second image around an unaltered central image. This second image appears more or less as a distinct halo, depending on the focal length, the aperture and the background. Choose between filters depending on the amount of space that you require for the halo compared to the subject.
Avoid focal lengths below 50 mm. Focusing must be carefully done : it is preferable to set the distance before putting the filter into the filter-holder. The halo and the diffusion diminish as the aperture closes, giving way to a double image. For advance verification of the effect produced, use the depth of field control. The effect is more pronounced when the subject is well-lit and the background is dark.
