A better evaluation would be to ask does this image contain information or data that I can use to make a diagnosis and can I accurately interpret that data? Based on that criteria a digital radiograph is (or at least has the potential to be) a much better diagnostic tool than a film radiograph. The reason is that a high resolution digital radiograph will capture more individual data points than film. In fact it will capture more data than we can see. The use of enhancement software will allow us to see differences in the data that we can not see with just our eyes. In other words the software can detect differences in the shades from black to white that we can not detect with our eyes.
