“The numbers on that and that review site suggest that many stops of the dynamic range, but I do not see it, my highlights are blown out, my shadows are noisy and blotchy”
Part of the problem is in how one sets the exposure. To set the exposure correctly it is good to know how the in-camera light meter works, and how it is calibrated. So, what is exposure meter calibration and why is it important?
Understanding of the exposure meter calibration determines the outcome of the exposure.
What does this mean? Well, let’s take a closer look.
RawDigger is Shareware now. You can use it free of charge during 30 days trial period. To continue using RawDigger after the end of the trial period please purchase the License.
RawDigger can be licensed as one of three Editions that differ in functionality and price:
Exposure Edition for everyday use: it displays RAW data in all modes (RGB, RAW Composite, and RAW per channel), indicates over- and underexposed areas, displays of RAW histogram, image statistics, statistics and histogram for selected area.
Research Edition is intended for camera/sensor evaluation (personal use and for preparing reviews, as well as to help with programming RAW data processing); it includes all the functionality of the Exposure Edition and 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.
Profile Edition helps to create sensor calibration data, linearization data, or device data for color profiling. It adds selection grids for faster processing of step wedges and color targets, as well as for calculating non-uniformity maps. Profile Edition allows to apply white balance, normalization, equalization (Flat Field), and filtering of outlying values before data export.
Note: RawDigger 0.9.20 will stop working on Nov 30, 2013
Raw data decoding support for all known Foveon-based cameras
For Sigma SD1 and Sigma Merrill cameras black level is computed automatically
For Sigma SD1 and Merrill cameras all raw sizes are supported, High, Medium, and Low. For Medium size RGB rendering is disabled because the aspect ratio in RAW is ~4800x1600 vs. ~3300x2200 in RGB
RGB rendering is supported for all cameras, but with different quality; for SD1 and Merrills it is more usable, for DPxx pre-Merrill series it is just usable, for SD9-SD14 and Polaroid x530 it is very rough.
For SD9-SD14 and Polaroid x530 cameras only Auto White Balance is available.
LibRaw library updated to support:
with full RGB rendering
Hasselblad Lunar, Stellar
Pentax K50, K500, Q7
Samsung Galaxy NX (EK-GN120)
Sony NEX-5T, ILCE-A7, ILCE-A7R, ILCE-A3000
preliminary RGB rendering (but of course RAW data is extracted in full)
For Sony and Samsung cameras black level is now based on EXIF information
For Sony cameras model name is now based on EXIF tag SonyModelID
Support for DNG files without compression tag is added
Added support for black level subtraction for non-Bayer (full-color) raw formats
Precision of the of floating point values is increased in exported files.
EXIF data can be copied to clipboard as a table and as a text, additional button for text export is available in the dialogue
Exporting Bayer RAW data as single channel (grayscale) TIFFs. This feature is most useful for exporting data obtained from DIY black and white cameras with removed CFAs (maxmax.com and similar methods).
It is now possible to switch off auto exposure compensation for RGB render display Preferences - Display Options - Automatic exposure correction for RGB render
Changes and improvements
The last set of Selection Grid parameters are now automatically saved and reused when the program is restarted.
The user can now control the set of folders that is displayed in the sidebar of the "Save.." dialogues (that is, export of RAW data and saving the measurement tables). Preferences - Misc Options - Sidebar folders in "Save.." dialogues:
Remember the list of used folders ("traditional" behavior) to display the list of previously used folders.
Standard list: include only Desktop, Documents, Pictures, TEMP, and Home folder.
Home Folder only
(This change has been implemented to address user complaints such as: If the list of used folders contains a slow or a disconnected (networked) disk, the "Save.." dialogues are very slow.)
For CGATS file export, the fields that can potentially contain a space are now enclosed in single quotes.
RAW/RGB data can be exported as an Uncompressed TIFF. For compressed TIFFS, the compression factor is increased (files are smaller).
Floating point numbers now contain no less than 4 significant digits (with the exception of percentages of over and underexposed pixels, where only 3 significant digits are used).
New Setting Preferences - Misc Options - Disable check for updates at startup Enabling this setting prevents RawDigger from checking updates when starting the program. Consequently, the scripts noCheckUpdates.reg for Windows platform and noCheckUpdates.sh for OS X platform are not provided anymore.
LibRaw has been updated, adding support for the following cameras: Panasonic LF1, Panasonic GX7, Fujifilm X-M1, Canon EOS 70D, Sony RX100II, Sony RX1R, Olympus E-P5.
Data export as TIFF Menu -> File -> Export TIFF) This feature allows exporting RGB rendition, composite RAW, or single RAW channel as a TIFF file. For more detailed discussion please see Data Export section in manual.
Better analyses of Canon sRAW data format New settings:
Data Processing -> Selection/Sample stats: discard abnormal pixel values
If the checkbox is set statistics for Selection and Sample discards 10% of highest and 10% of lowermost pixel values to filter off dust, scratches, small specular reflections, and other target/sensor defects
Fast Raw Viewer is the first and the only dedicated tool specifically designed and developed for extremely fast display, visual and technical analysis, basic corrections, sorting and setting aside or directly transferring for further processing of RAW images.
