Cokin P345 Cokin Double Mask 2 Filter
The Double Mask system allows you to combine two scenes in one. The effect is achieved by exposing each frame twice, one with each filter contained in the Double Mask set. One filter covers the center of the image, the other the surrounding frame. The system comes in two sizes: #342 and #345, which has a larger center spot. This double exposure can be done either by re-cocking the camera without advancing the film or by exposing the whole roll of film with the first filter and then rewinding the film to its initial position and exposing each frame again with the second filter. It is recommended that you measure the exposure without the mask in place.This filter measures 85 x 85mm and fits the Cokin P series holder.
Cokin filters were invented by professional photographer Jean Coquin. By using square filters like Cokin's, which fit into a holder and are attached to a lens via an adapter ring, the photographer has a number of immediate advantages. There is no need to duplicate filters to fit different size lenses, up to three filters can be used at once to create unique effects, and the photographer has control over the positioning of the effect on the photograph.
