RawDigger by LibRaw, LLC, is a tool to visualize and examine pure raw data as the camera has recorded it. In essence, it is a microscope of sorts that lets you drill down into raw data. RawDigger 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. If you happen to have any raw files from cameras that are not yet supported, including new and pre-production models.
Some unique RawDigger features:
RawDigger 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 allows determining how exposure meter is calibrated and what raw level corresponds to the midpoint of in-camera histogram. That is, RawDigger lets you establish the headroom in highlights and obtain optimal exposures.
For ETTR practitioners, RawDigger makes it very simple to compare raw histogram to in-camera histogram and account for the difference, making the exposures as much “to the right” as possible.
RawDigger helps determining 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 RawDigger accordingly.
RawDigger is a useful tool for examining how the relative per-channel underexposure depends on the color of light.
RawDigger 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 RawDigger helps establishing 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 different light.
RawDigger can be used to check the amount of vignetting caused by the lens and the sensor.
RawDigger helps determine the idiosyncrasies of both camera and raw convertor by providing a true view into the raw data and comparing it to the results obtained through raw conversion.
Some of the more advanced features, depending on the RawDigger edition, include:
RAW data export as TIFF.
Plot and save per channel raw data histograms for both the entire file and for an arbitrary rectangular area of the file (selection). The histograms can be saved as graphics or as a table for further external processing.
Calculate the statistics per channel (minimum, maximum, average, root-mean-square deviation) for the entire file and for an arbitrary rectangular selection.
Calculate the statistics per channel and save the results 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 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.

RawDigger 的 LibRaw，LLC，是一种工具来可视化和审查纯净的原始数据，摄影机留下了它。从本质上说，它是显微镜类使您可以深入到原始数据。RawDigger 并不改变原始数据在任何方式。RawDigger 不是原始的转换器。相反，它允许您查看的数据，将由原始转换器使用。RawDigger 支持几乎所有的相机有原料的能力。新相机的支持通常后原样品成为可用的几周内实现。如果你碰巧有任何从尚不支持，包括新的和预生产的型号的相机原始数据文件。
一些独特的 RawDigger 功能:
RawDigger 显示真正的原始数据，很大的不同在照相机直方图直方图和直方图提出最原始的转换器。
过度曝光 (OE) 指标会告诉你到底在拍摄什么方面都吹出和在哪种颜色 channel(s) 它发生了(最好如果通道视图中使用)。
RawDigger 允许确定曝光表如何校准和什么原料级别对应的相机在直方图中点。那就是，RawDigger 允许您建立的亮点净空和获得最佳曝光。
从业人员 ETTR，RawDigger 使非常简单比较原始直方图在照相机直方图和尽可能考虑差异，使尽可能多"向右"曝光。
RawDigger 可以帮助确定过度"blinkies"开始在显示屏上，知道多少净空高度是仍然可用后blinkies 开始显示的原始水平。
如果阴影看起来斑点，无色的或者在阴影的细节是不好解决，你将能够确定多少他们都曝光不足，因此在 RawDigger 中设置曝光不足 (UE) 指标。
RawDigger 是一个检查如何相对每通道曝光不足取决于光的颜色的有用工具。
RawDigger 是比任何曝光表进行的填充光及繁殖光设置 (在色彩平衡和跨背景亮度均匀度) 均匀性的评价更准确。
对于工作室摄影 RawDigger 有助于建立适当的光过滤实现清洁一阴影里，在镜头上。
风景摄影师可能想要使用 RawDigger 来确定对镜头，检查中立的两极分化和中性密度筛选和可能，选择色彩校正和色彩补偿滤波器，在不同的光线中使用筛选器的影响。
RawDigger 可以用于检查产生晕影造成的镜头和传感器的数量。
RawDigger 可以帮助确定的相机和原始变换器的特性所提供的原始数据到一个真正的视图并将其通过 raw 转换得到的结果进行比较。
一些更高级的功能，具体取决于 RawDigger 版本，包括:
原始数据导出为 TIFF。
绘制和保存每通道原始数据直方图整个文件，该文件 (选择) 任意矩形区域。直方图可以保存，作为图形或表的进一步对外加工。
计算每个通道 (最小、 最大、 平均、 均方根偏差) 为整个文件和任意矩形选择统计。
计算每个通道的统计数据并将结果保存在处理友好的形式-CSV，CGATS (为任意数量的文件的矩形区域)。
列表形式 (用于相机和使用这类曲线的位置的原始数据格式) 保存原始数据文件的压缩曲线。
RawDigger 是在几个版本中可用:
曝光版供日常使用，旨在帮助那些严重有关提取最大质量从摄像头中得到精确的曝光。
曝光版显示在所有模式 (RGB、 原料的组合物和原料每个通道) 中的原始数据，表明在高和曝光不足的区域，显示原始直方图，图像的统计，以及统计和直方图的选定区域。
研究版是为相机/传感器评估和统计分析的原始数据。它是适用于广泛的任务，从个人使用和编写审查和到编程原始数据处理。
研究版增加了 TIFF 出口，多个选定的领域通过样品，采样数据; 表统计和直方图在多个样品，导出采样数据作为 CSV 和 CGATS。
配置文件版是为那些需要创建传感器校准数据、 线性化数据或设备进行颜色分析的数据。
配置文件版本添加选择网格的步梯和颜色的目标，更快的处理以及计算非均匀映射。配置文件版允许应用白平衡，归一化、 均等 (平场)，和筛选的数据导出前生僻的值。
