An investigation was made to determine the correlation between the maximum density and log exposure range of photographic paper when making "quality" prints. The 1966 ANSI log exposure range formula assumes that papers which have the same log exposure range but differ in maximum density will print the same negative successfully. It has been shown with 27 Judges that when the 1966 ANSI log expo sure range formula is used the maximum density has an effect on the effective log exposure range such that papers which have the same log exposure range but differ in maximum density will not print the same negative successfully. Effective log exposure range factors were determined so that papers of different maximum density could be compared more readily.
