Multiple files can be read and averaged (and saved) to facilitate measurements of fixed-pattern noise (in Stepchart, Colorcheck, and Light Falloff) and image stabilization (SFR). Highly distorted regions of interest (ROIs) can be analyzed with Colorcheck and Stepchart. New ΔE measurements and hot/dead pixel options have been added to Light Falloff.
Imatest Master and Studio have been introduced, replacing Pro and Light. Support for Bayer RAW images has been strengthened.
Two new options are available for refining multiple ROI selections in repeated SFR runs (Imatest Master only). (1) Multi-ROI fine adjustment (shift, magnify, reduce), and (2) Automatic ROI refinement. These speed up test sequences of different cameras and lenses, where it may be difficult to maintain exact chart alignment.
RAW files are supported for a large number of digital cameras using Dave Coffin’s dcraw program. Files are converted with minimal signal processing— no sharpening or noise reduction. This allows the true performance of cameras and the behavior of raw converters to be analyzed.
Chromatic Aberration is now measured as percentage of the distance from the image center. This is an improvement over area in pixels because CA tends to be proportional to that distance. The new measurement is relatively independent of camera pixel count and measurement location.
A checkbox on the main window allows you to turn off automatic expansion of the figures for high resolution screens (>1280 pixels wide). The smaller figures are better for posting on the web.
