| Module |
Light |
Pro (includes all features of Light) |
| |
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. |
| MTF Compare |
(Pro only) |
Allows MTF results calculated in SFR and saved in CSV files to be compared for a wide variety of cameras, lenses, and imaging systems. |
| Rescharts |
Analyze slanted edges (similar to SFR) and charts that vary in spatial frequency for MTF. Highly interactive. |
Adds color moiré analysis to Log Frequency, Log F-Contrast, which analyzes fine detail lost as a result of software noise reduction, and Star Charts. |
