![]() So if, for example, the set covers ISO 1600, 10, if I brighten the ISO 1000 RAW file by 1⅓ EV, it should show almost identical shadow detail to the ISO 2500 file, but of course it will have retained far more highlight detail. This means that in fairly low light, my bracketed set will have the same aperture and shutter settings for each shot, but different ISO sensitivities. ![]() The D800 also has an excellent Auto-ISO program, so I normally use this when shooting hand-held and bracketing. I realize that the sensor in my D800 is relatively ISO-invariant, so that above ISO 800 it loses approximately a stop of dynamic range for each extra ISO stop. ![]() My dilemma regarding whether to save or delete a RAW file when the corresponding JPEG has burned-out areas, and bracketing has given me a pair of files with a lower exposure, applies primarily to low ISOs. On the other hand, I assume the smaller the dynamic range, the less detail will be lost to the JPEG. I realize that retaining as much dynamic range as possible is even more valuable at high ISOs than low, because the sensor’s dynamic range is reduced. Profile Edition allows applying white balance, normalization, equalization (Flat Field), and filtering of outlying values before data export.Click to expand.I don’t remember much comment about ISO settings when various experts have referred to RAW files having more headroom for recording highlights than is shown in out-of-camera JPEGs. Profile Edition adds selection grids for faster processing of step wedges and color targets, as well as for calculating non-uniformity maps. Profile Edition is for those who need to create sensor calibration data, linearization data, or device data for color profiling. 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. 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 is meant for camera/sensor evaluation and statistical analysis of raw data. RawDigger is available in several editions:Įxposure 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.Įxposure 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. It helps prepare data for calculations of color transforms and camera profiles. It helps to determine how exposure meters are calibrated, what is the headroom in highlights, which camera setting affect RAW data and how, how a raw converter interprets RAW data and which "hidden" compensation it applies, what tone curve is used for in-camera JPEGs and in a converter. RawDigger can be used to solve a multitude of tasks, including the diagnosis of different problems, such as those with studio lights, lenses, flash, shutter, and aperture accuracy and repeatability, camera drifts, exposure, noise. The primary goals of RawDigger are to help you get better shots and increase the number of "keepers" through better knowledge of the "digital film" you are using, that is, RAW data. In essence, RawDigger is a microscope of sorts that lets you drill down into the RAW by means of visualizations, histograms, and statistics over selections and samples.
