Abstract
In a method of producing converting data, a first characteristic curve showing relationship between density value and exposure amount is obtained by forming images on a first photographic material with plural different amounts of exposure and by measuring density values of the formed images. Digital exposure amount data is determined so as to represent the exposure amount of the first characteristic curve. The first characteristic curve is modified so as to show relationship between the density value and the digital exposure amount data by changing the exposure amount to the digital exposure amount data. A second characteristic curve showing relationship between density value and digital input value for exposing means is obtaiend by forming images on a second photographic material by the exposure means based on plural different digital input values and by measuring density values of the formed images. Then, converting data to convert the digital exposure amount data into the digital input value are obtained based on the first characteristic curve and the second characteristic curve.
