Q What Is the method used by animation studios to effect a gradual, overall change of the color of the lighting In the same scene as for example predominantly blue to red? An example of this Is In the old Walt Disney movie, "Sleeping Beauty", where one of the fairies puts the two kings, Hubert and Stephen to sleep in the castle. As they drift into slumber, the scene, which is multi-colored, gradually takes on an overall greenish hue, resulting in a near-monochromatic color scheme.

A The effect is very simply done by sliding colored gelatin fHters before the lamps lighting the animation table carrying the artwork being photographed, or by having two sets of lamps set up to light the table, with both sets working from dimmers. In the latter scheme, one set of lights (of one color) is gradually dimmed out and the other color lights are brought up in density as shooting of the scene progresses.

Q Would it be possible to tell me how one creates artificial cobwebs and how one goes about creating "ice flowers" often found on windows on very cold winter days?

A The usual way to make artificial cobwebs is to use a small fan, removing the guard from in front of the vanes. To the end of the shaft in front of the blades attach a special metal container. Rubber cement is poured into the container and the fan is turned on. As the fan turns, the centrifical force expels the cement into the wind stream. The air partly dries the rubber cement as it is blown out. Direct the fan toward the area in which you want the cobwebs and in a cross-movement of the fan you will create the pattern of cobwebs you desire.

The container is shaped like two saucers placed face to face with about a six-inch diameter; two-inches thick at the center and tapering off to about one quarter inch at the rim. …
