a method for deriving a color negative film developer composition and processing conditions for developing a photographic film image which is optimized for subsequent digital scanning and digital image file manipulation , which allows for optimum rapid development processing of the film is disclosed . the process includes identifying at least one independent variable that has a first order effect on the density of at least one of the red , green , and blue dye images of the developed image , selecting a desired range of values for the independent variables identified , formulating an experimental design that includes desired independent variables over the desired range of values , performing the experiment to obtain statistically significant values for desired dependent variables , applying the values to a mathematical model capable of providing a formula for optimizing responses to the dependent variables , and using the formula to identify desired optimal developer composition and processing conditions resulting in an developed image in which the subsequent required digital scanning and digital image file manipulation is reduced .
