RawDigger

In essence, RawDigger is a microscope of sorts that lets you drill down into the RAW by means of visualizations, histograms, and statistics over selections and samples. The primary goals of RawDigger are to help you get better shots and increase the number of “keepers” through better knowledge of the “digital film” you are using, that is, RAW data.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

New features

• Grid save/load
• CSV data export: additional fields (Camera vendor/model, ISO, shutter, exposure)
• File natural sort order for next/prev files (and in file dialogs)
• GUI toolkit used updated to Qt 5.12
• Optional OpenGL-based bitmap drawing (may be faster on old CPU/modern GPU combo)
• 16-bit TIFF RGB-rendered data export (64-bit RawDigger builds only)
• RGB rendering export: ability embed color profile in the output TIF (3-channel TIFFs only)
• Exiftool updated to version 11.85
• Fixed incomplete low-sensitivity pixel processing on Sigma SD Quattro half-res filesRawDigger doesn’t alter the raw data in any way. RawDigger is not a raw convertor. Instead, it allows you to see the data that will be used by raw convertors.RawDigger supports nearly all cameras that have raw capability. Support for new cameras is usually implemented within few weeks after raw samples become available.

  General Tools and Features

  • RawDigger allows one to display and research the real Raw Histogram of the raw data, which greatly differs from the in-camera histogram, as well as histograms presented by most of the raw converters.
  • To facilitate accurate raw image study, the histogram can be displayed in different modes, over the whole image or rectangular selections of the portions of the image.
  • The histogram can be exported for further study as a spreadsheet (CSV), or as a PNG for presentation.

  The Overexposure (OE) and Underexposure (UE) Indications will show you exactly what areas of the shot are blown out or underexposed and in which color channel(s) it happened (best if used in per-channel view).

  • Calculate the statistics per channel (minimum, maximum, average, root-mean-square deviation StdDev) for the entire file and for an arbitrary rectangular selection.
  • Save the results of the calculated statistics in a processing-friendly form – CSV, CGATS (for an arbitrary number of rectangular areas of the file).
  • Save the compression curves of raw files in a tabulated form (for cameras and raw data formats where such curves are used).

  • RawDigger Full Version Features

    • Digger displays the real histogram of the raw data, which greatly differs from the in-camera histogram and histograms presented by most of the raw converters.
    • Overexposure (OE) indicator will show you exactly what areas of the shot are blown out and in which color channel(s) it happened (best if used in channel view).
    • RawDigger Serial key allows determining how exposure meter is calibrated and what raw level corresponds to the midpoint of an in-camera histogram. That is, Digger lets you establish the headroom in highlights and obtain optimal exposures.
    • For ETTR practitioners, RawDigger makes it very simple to compare raw histograms to an in-camera histogram and account for the difference, making the exposures as much “to the right” as possible.
    • RawDigger Keygen helps to determine the raw level at which the overexposure “blinkies” start on the camera LCD and to know how much headroom is still available after the blinkies start showing.
    • If the shadows look blotchy, colorless, or details in shadows are poorly resolved you will be able to determine how much they are underexposed and set Underexposure (UE) indicator in Digger accordingly.
    • Digger is a useful tool for examining how the relative per-channel underexposure depends on the color of light.
    • RawDigger Portable is more precise than any exposure meter for the purpose of evaluation of the uniformity of fill light and reproduction light setups (in terms of the evenness of both color balance and luminosity across the background).
    • For studio photography, Digger helps to establish the proper light filtration to achieve the cleanest possible shadows on the shots.
    • Landscape photographers may want to use RawDigger to determine the effect of the filters on the lens, to check neutrality of polarizing and neutral density filters and, possibly, to select color correction and color compensation filters to use in a different light.
    • RawDigger Full Cracked can be used to check the amount of vignetting caused by the lens and the sensor.
      it helps determine the idiosyncrasies of both camera and raw converter by providing a true view of the raw data and comparing it to the results obtained through raw conversion.
