Imatest™ version comparison

Module Studio Master (includes all features of Studio)

Everything an individual photographer needs to test cameras, lenses, and printers. The full-featured version for professionals and imaging system developers.
SFR Edge, MTF (SFR), and Chromatic aberration analysis Batch runs (multiple input files); MTF calculated for any edge angle; edge and MTF display for R, G, and B channels in addition to Y
Colorcheck Tonal response and noise analyses for B&W patches; La*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
Stepchart

Tonal response, noise, dynamic range analysis, and veiling glare Batch runs (multiple input files); density values can be read from a file; tonal response for separate R, G, B, Y channels (in figure 3); analyzes the Applied Image QA-61 (ISO-16067-1), QA-62, ST-51 (EIA grayscale), ST-52 (ISO-14524) 12-patch OECF chart, 20-patch OECF charts, and the ISO-15739 (Noise) chart.
Light Falloff Light falloff (luminance channel) displayed in normalized pixel levels and f-stops Batch runs (multiple input files); Light falloff for R, G, and B channels; histograms for R, G, and B channels; display dead and hot pixels; color shading (sensor nonuniformity); noise detail
Print Test Print tonal response and gamut in La*b* and xyY spaces Print gamut in HSL representation
Test Charts SFR Quadrants, SFR rectangles, Grid (for Distortion) Star, Log-frequency contrast/gradient, Zone plate, Scalable Vector Graphics (SVG) charts
Distortion Calculate distortion for 3rd and 5th order polynomial and tan/arctan approximations. Batch runs (multiple input files); Lens decentering; Intersection point plot; Corrected image display
Multicharts Analyzes the 24-patch Colorchecker and the IT8.7. Highly interactive. Includes the Colorchecker SG, Grayscale step charts, and Special Charts (squares arranged on a circle and several Applied Image and ISO charts). Calculates Color correction matrix.
