Digital film recorders play a key role bridging digital imagery and photographic media. The purpose of this research was to characterize the relationship between digital drive signals controlling the exposure of positive 35mm film and the spectral transmittance of the processed film. First, the Beer-Bouger law was verified relating dye concentration and spectral transmittance. Second, an empirical nonlinear relationship was found between status A densities and dye concentration to facilitate the conversion from integral to analytical density alleviating the need for spectral transmittance measurements. Third, the relationship was found between digital drive signals and integral density. This complex relationship modeled the well-known inter-image effects of transparency films: A combination of principal component analysis and cubic spline interpolation was used.
