Use Edit>Fill… to fill the red layer with the foreground color:ĭo the same with the green and blue layers. When the colors are all filled in, the layers will look like this:Ĭlick on the foreground color and enter the values for full red as follows: Then make a fourth layer for the white balance target color. To make the red, green, and blue images in Photoshop, create an image about the shape of your format. Bring that picture into Rawdigger and look at the EXIF WB coefficients and the raw values to see how well you did.Read the UniWB target RGB values from the output cells, and fill the test target with that color in Photoshop.Enter the desired raw value for the UniWB target.Enter the color space gamma into the spreadsheet.Enter the average values of the red, green, and blue raw pixels into the appropriate columns in the spreadsheet. In any RGB color space within the gamut of your monitor for which you know the gamma (sRGB is probably the safest choice), make three exposures: one at R=255, G=0, B=0, one at R=0, G=255, B=0, one at R=0, G=0, B=255.There’s a detailed explanation at the end of this page. Here’s an “.xls” version if your version of Excel is old: OneStepUniWB This spreadsheet (Right-click on it and select “Save target as” to download it.Excel, or another spreadsheet program that can operate with Excel files.Rawdigger, or another program that lets you look at the average values of the ref, green, and blue pixels in raw files.Photoshop, or another image editing program that lets you create images with arbitrary colors.The setup described in the preceding page.Supported OS: Windows 11, Windows 10, Windows 8.Technical Details and System Requirements 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.Can be used to check the amount of vignetting caused by the lens and the sensor.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.For studio photography RawDigger helps establishing the proper light filtration to achieve the cleanest possible shadows on the shots.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).A useful tool for examining how the relative per-channel underexposure depends on the color of light.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.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.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.That is, RawDigger lets you establish the headroom in highlights and obtain optimal exposures. Allows determining how exposure meter is calibrated and what raw level corresponds to the midpoint of in-camera histogram.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).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.Instead, it allows you to see the data that raw converters will use. It doesn’t alter the raw data in any way. In essence, it is a microscope of sorts that lets you drill down into raw data. This program is a tool to visualize and examine pure raw data as the camera has recorded it. You can also FREE download Infonautics File Date Corrector. It is used to visualize & examine raw data as the camera has recorded. Free Download RawDigger full version standalone offline installer for Windows.
