Abstract
Apparatus for influencing the color of a beam of printing light in a photographic printer has three sets of coplanar filters which are movable into and from the path of printing light. The filters are mounted on holders in the form of slides, levers or pulleys and are pivotable or reciprocable between inner end positions in which they form a substantially uninterrupted composite filter extending across the entire beam of printing light and partially or completely retracted positions. The filters of each set are movable by separate actuating means which can move all filters of the respective set simultaneously toward or from the inner end positions. such actuating means may employ endless flexible elements, flexible elements of finite length, or rings which have cam slots for followers provided on the holders for the filters of the respective set.
