LADIES’ EVENING.

CINE CLUB ENTERTAINS. Members bf the Palmerston North Cine Club held a ladies’ night on Monday, when, to a large attendance, Dr. T. R. Vernon, vice-president, explained the process of making colour films. Mr J. Thomas presided. Dr. Vernon stated that, in 1855, Clerk Maxwell, a physicist, invented the three-colour process. From this developed two processes, additive and subtractive. In ordinary still photography the additive method was used. White light could be split up into its component parts—red, orange, yellow, green, blue, indigo and violet—by a prism or raindrops. The main divisions were red, green and blue, and by combining these in equal proportions there were obtained white light, or in other proportions any colour in nature. This process of adding colours to give a mixture was the additive method and was used in the three-colour printing process for book illustrations and reproductions of famous pictures. Colours could also be produced by subtracting others from white light. Thus blue-green could be formed by allowing white light to fall on a surface which absorbed red —the blue-green was reflected. This was the subtractive process.

The speaker also'traced the development of colour motion pictures. A colour programme followed, including “Swamp Clearing,” by Mr D. Chrystal!.'This showed flaxcutting at Himatangi, and clearing fires. Mr C. Bayliss followed with, a film of Chicago, Niagara Falls, the Rockies and Vancouver. Mr H. L.
