Abstract: A new sound negative film, type 258, called ST 8, has been designed to improve the quality of optical soundtracks, especially in the super-8 format. Using an orthochromatic sensitization, a higher sensitivity is obtained with better optical characteristics such as sharpness and graininess, after processing in a conventional phenidone-hydroquinone developer. The higher sensitivity is useful for large film formats. Its increased optical quality results in a remarkable sound quality, especially in super 8. The photographic characteristics, such as darkroom sensitivity, latent image and influence of developing time have been optimized so that the new ST 8 film is readily adapted to any laboratory practice. The results obtained on cross modulation and frequency tests after printing on Gevacolor print film type 985 are discussed.
