Abstract

For obvious reasons people in the field claim that measured data do not agree with what they perceive. Scientists reply by saying that their data are "true". Are they? Since images are made to be looked at, a request for data meaningful for what is perceived, is not foolish. We show that, when noise is characterized by standard density fluctuation figures, a good correlation with noise perception by the naked eye on a large size radiograph is obtained in applying microdensitometric scanning with a 400 micron aperture. For other viewing conditions the aperture size has to be adapted.
