Save the compression curves of raw files in a tabulated form (for cameras and raw data formats where such curves are used). The histograms can be saved as graphics or as a table for further external processing.Ĭalculate the statistics per channel (minimum, maximum, average, root-mean-square deviation) for the entire file and for an arbitrary rectangular selection.Ĭalculate 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). Plot and save per channel raw data histograms for both the entire file and for an arbitrary rectangular area of the file (selection). Some of the more advanced features, depending on the RawDigger edition, include: 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. Ive previously written about the Sony ARW raw format, which uses 11+7 bit lossy compression (data is thrown away). RawDigger 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. 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).įor studio photography RawDigger helps establishing the proper light filtration to achieve the cleanest possible shadows on the shots. ![]() Nuclear medicine residency salary average. RawDigger is a useful tool for examining how the relative per-channel underexposure depends on the color of light. Rawdigger download google Baby hat crochet patterns with ear flaps. 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 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. That is, RawDigger lets you establish the headroom in highlights and obtain optimal exposures.įor 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 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). 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. Vielleicht ja ganz interessant für den einen oder anderen.
