Abstract
Data are given on the amount and distribution of light which can be obtained on the transparent screen with regular high-intensity carbons and various optical systems. These optical systems include two condenser-type systems and two relay-condenser-type systems used with f/2.3 and f/2.0 objective lenses. Values are obtained which are in line with the recommendations on Process Projection Equipment by the Research Council of the Academy of Motion Picture Arts and Sciences. In addition, characteristics of two new carbons developed for this purpose are given. These are also evaluated in the relay-condenser system and give the advantage of additional light, or the same light at lower energy input.
