Access, view, and analyze the pure raw data as recorded by your DSLR and certain video cameras with RawDigger Research Edition from LibRaw LLC. RawDigger is not a raw converter; it is a microscope of sorts that lets you drill down into your image files and visualize the data that will be used by raw converters. With this software, the isolation layer normally imposed by raw converters becomes transparent.
The Research edition is meant for camera/sensor evaluation and statistical analysis of raw data. It is suitable for a wide range of tasks, from personal use and preparing reviews to programming raw data processing. It is also useful for the study of lens flare and glare and the resulting characteristic curves, checking lens transmission symmetry, and setting even lighting.
This edition of the software supplements the Exposure edition's primary features with the ability to export raw files as TIFFs, capabilities for sampling multiple selected areas and generating tables of sampled data, statistics and histograms over multiple samples, and exporting sampled data as CSV and CGATS file formats.
RawDigger's basic functionality can help you determine the calibration of an in-camera exposure meter and quantify different vignetting sources. It also allows you to use spot-metering, exposure compensation, and manual exposure settings more efficiently and reliably; and to monitor and improve studio lighting setups in terms of white balance/light uniformity, and dynamic range.
To facilitate accurate raw image study, RawDigger's indicators for over- and underexposed image areas show you exactly where and in which color channel(s) details are blown out or have noisy shadows, with statistics to indicate the percentage of over- or underexposed pixels. Additionally, the histogram for either the entire file or an isolated image segment can be viewed in all modes (RGB, raw composite, and raw per channel). It can also be exported for further study as a spreadsheet (CSV) or a graphic file (PNG) for presentation.
RawDigger supports all raw formats (including DNG) associated with a list of more than 800 supported cameras, and frequent updates are made to support new DSLR and cell phone models. The software can read files from any media, from a flash card to a network server. It works on a variety 32/64-bit Windows, Intel-based Mac platforms and Linux Wine-1.2.3; Wine (1.3.37-0ubuntu1~ppa1~lucid1) and Debian testing.
This version of RawDigger is delivered as a download, and the license key can be installed on up to two computers simultaneously.
