RawDigger是一种可视化和检查纯原始数据的工具,就像相机所记录的那样。本质上,它是一种显微镜,可以让您深入到原始数据。RawDigger不会以任何方式改变原始数据。RawDigger不是一个原始转换器。相反,它允许您查看原始转换器将使用的数据。

一些独特的RawDigger功能:

•RawDigger显示的是原始数据的真实直方图,这与大多数raw转换器呈现的相机内直方图和直方图有很大区别。

•过度曝光(OE)指示器会准确地显示照片的哪些区域被放大了,以及是在什么颜色通道中发生的(最好是在通道视图中使用)。

•RawDigger允许确定曝光计是如何校准的,以及什么原始水平对应于相机内直方图的中点。也就是说,RawDigger让你建立高光的净空空间,获得最佳曝光。

•对于ETTR从业者来说,RawDigger可以非常简单地比较原始直方图和相机内直方图,并说明差异,使曝光尽可能“向右”。

•RawDigger可以帮助确定相机LCD上开始出现过度曝光的“闪光点”的原始水平,并知道在闪光点开始出现后还有多少空间可用。

•如果阴影看起来有斑点,无色,或阴影细节解决不佳,你将能够确定它们的曝光不足程度,并在RawDigger中相应地设置曝光不足(UE)指示器。

•RawDigger是一个有用的工具,用于检查相对每通道曝光不足如何取决于光的颜色。

•RawDigger比任何曝光表都更精确,用于评估填充光和再现光设置的均匀性(在色彩平衡和背景亮度的均匀性方面)。

•对于工作室摄影,RawDigger帮助建立适当的光过滤,以实现最干净的阴影的镜头。

•风景摄影师可能需要使用RawDigger来确定镜头滤镜的效果,检查偏光滤镜和中性密度滤镜的中立性,可能还需要选择在不同光线下使用的色彩校正和色彩补偿滤镜。

•RawDigger可以用来检查由镜头和传感器引起的光晕的数量。

RawDigger通过提供原始数据的真实视图,并将其与通过原始转换获得的结果进行比较,帮助确定相机和原始转换器的特性。

RawDigger 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.

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.
