Comparision between versions SFR Studio Master Edge and MTF (SFR) plot Chromatic aberration plot Batch runs (multiple input files) 6 max. SFR Any Angle: Calculate MTF for any edge angle. Display edge and MTF for R, B, and B channels, in addition to Y (luminance) channel Colorcheck Studio Master Tonal response and noise analyses for B&W patches L*a*b* color error and Color analysis Batch runs (multiple input files) User-supplied reference files Noise analysis for R, G, B, C, M, and Y patches; noise spectrum Multicharts Studio Master Interactive analysis of tones and colors in the 24-patch GretagMacbeth Colorchecker and IT-8.7 charts Analysis of the GretagMacbeth ColorChecker SG User-supplied reference files Special charts: analyze patterns of squares arranged on a circle as well as the Applied Image and ISO charts also analyzed by Stepchart for Imatest Master . Stepchart Studio Master Tonal response, noise, and dynamic range analysis Batch runs (multiple input files) Tonal response for separate R, G, B, Y channels (figure 3) Chart density (reference) values can be read from a file. Analyzes the Applied Image QA-61 (ISO-16067-1), QA-62, ST-51 (EIA grayscale), and ST-52 (ISO-14524) charts, and the ISO-15739 (Noise) chart.
