An imaging system and method employ a linear perceived optical density interface that produces a substantially linear relationship between digital image values generated by an input imaging device and perceived optical densities of corresponding pixels within a visible representation of the image on film. The interface produces a linear change in perceived optical density in response to a linear change in the digital image values, enabling a system user to achieve predictable changes in appearance characteristics by simply adjusting the digital image values. The user can adjust the appearance characteristics in a flexible manner, without being constrained to a set of fixed transfer functions. The user can also perform desired formatting of the image at the input imaging device. The interface provides a single transfer function that is commonly applicable different input imaging devices, such that development of modality-specific transfer functions is unnecessary. The interface also eliminates the extensive hardware previously necessary for supporting a fixed set of transfer functions and formatting options, reducing cost and complexity.
