The horizontal axis for both plots is the chart zone— proportional to the distance along the chart. Here are the results of scanning the Kodak step tablet with the Epson scanner with transparency unit set for negatives. Then, we can use this dictionary to look up the critical Q-values dictionary values for different sample sizes dictionary keys. This chart is also used for SFR measurements. Several features resemble the Koren test chart described in Lens testing pre- Imatest. A range of tones over which the RMS noise, measured in f-stops, is under a maximum specified value. Note that in a later paper in , Dixon and Dean [3] revisited the calculation of the Q-value and reported different equations for different scenarios:. Note that only tec sd point may be rejected from a data set using a Q test.
