Use of a Waveform Monitor in the Television Film Preview Room
While the television film preview room provides a critical condition for evaluation of films for color balance and tone reproduction, it is difficult to detect visually the presence of undesirably low densities in white areas. Presence of such “super-whites” can cause problems in television transmission. To remedy this deficiency of the optical preview room an inexpensive waveform monitor was assembled from a low-priced industrial monochrome television camera and a simple oscilloscope. The device is easily calibrated to indicate the presence of densities less than the recommended minimum of 0.30 for white objects. — This addition to the optical preview room should be useful to film laboratories in timing television prints, and to photographers and film producers in assessing the suitability of their films for telecasting.
