RawDigger

RawDigger can be used to solve a multitude of tasks, including the diagnosis of different problems, such as those with studio lights, lenses, flash, shutter, and aperture accuracy and repeatability, camera drifts, exposure, noise. It helps to determine how exposure meters are calibrated, what is the headroom in highlights, which camera setting affect RAW data and how, how a raw converter interprets RAW data and which "hidden" compensation it applies, what tone curve is used for in-camera JPEGs and in a converter. It helps prepare data for calculations of color transforms and camera profiles.

RawDigger is available in several editions:

Exposure Edition is for everyday use and is intended to help those who are serious about extracting the maximum quality from the camera to get precise exposures.

Exposure Edition displays RAW data in all modes (RGB, RAW Composite, and RAW per channel), indicates over- and underexposed areas, displays RAW histogram, image statistics, as well as statistics and histogram for selected area.Research Edition is meant for camera/sensor evaluation and statistical analysis of raw data. It is suitable for a wide range of tasks, starting from personal use and preparing reviews and all the way to programming RAW data processing.

Research Edition adds TIFF export, multiple selected areas via samples, tables of sampled data; statistics and histograms over multiple samples, exporting sampled data as CSV and CGATS.Profile Edition is for those who need to create sensor calibration data, linearization data, or device data for color profiling.

Profile Edition adds selection grids for faster processing of step wedges and color targets, as well as for calculating non-uniformity maps. Profile Edition allows applying white balance, normalization, equalization (Flat Field), and filtering of outlying values before data export.
