Double Mask
The Cokin filter holder and the Double Mask system allow you to combine two scenes in one, creating a photomontage in your camera. These pictures are produced by exposing each frame twice, one with each filter in the Double Mask set. Before you can use this set you must make sure your cameras can make multiple exposures .
Also see Multiple Exposure Effects for a cool effect with this filter set and the Multi-image 201 filter.

Helpful hints :
Set your camera to make a double exposure, unlock your Autofocus, and measure light without the filter. Use an aperture between f5.6 and f8 for focal length from 21mm to 35mm, and between f11 and f16 for focal lengths from 50mm to 105mm, and then proceed as follows. First insert the first mask (small dot in center) dead centre in the COKIN Filter-holder (second groove fror the lens). Frame and take first shot. Next replace the first mask with the second (first groove for Ref. 345, third groove for Ref 342). Then take the second shot.
Use lenses from 50 to 105 mm. Wide-angle lenses yield a smaller center. Long-focus lenses yield a larger center. Small apertures yield a sharper and smaller hole, Large apertures yield a more diffused and larger hole. Measure the exposure without the mask in place.
created unique photos by rephotographing slides projected on a simple paper screen, You can mount Cokin filters over the lens of your slide projector. This way, you can recreate your photographs anytime. In the winter, for instance, when you review the slides of your last seaside holiday, It is advised that you use a duplicating color film and mount the camera on a tripod if you need to use long exposures.
