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.
