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.

According to Iliah Borg, the Nikon D850 is calibrated to get a saturation of 10% under these conditions. Saturation occurs at around 15780, so saturation is 9%. Using Rawdigger, I get a raw pixel value of 1380. The values from the camera and LR with no exposure correction are slightly hot, while with the -0.35 EV correction the pixel value is very close to mid-grey. With Lightroom I get 135 with no exposure adjustment and 115 with -0.35 exposure correction. With my D850 set to sRGB and using the Nikon Standard picture control, I get an sRGB value of 132 from the in camera JPEGs. ![]() If you have Rawdigger, look at the raw pixel value and determine percent sensor saturation. The -0.35 value is to correct for the hidden exposure correction (see link) that LR applies for the D850. Look at the pixel value in the center of the images, with the in camera JPG and Lightroom raw conversions using exposure 0, and exposure -0.35. It doesn't matter if the target is white or grey, since the metered exposure will be the same the camera meter has no way of knowing scene reflectance. Take exposures of a uniform white wall or other uniformly lit scene with the camera set to capture NEF+JPG. As pointed out previously, brightness on the LCD is not good since the backlight brightness can vary. How are you judging exposure for in camera and Lightroom.
