DisplayCAL (formerly known as dispcalGUI) is a display calibration and profiling solution with a focus on accuracy and versatility (in fact, the author is of the honest opinion it may be the most accurate and versatile ICC compatible display profiling solution available anywhere). At its core it relies on ArgyllCMS, an advanced open source color management system, to take measurements, create calibrations and profiles, and for a variety of other advanced color related tasks.
Calibrate and characterize your display devices using one of many supported measurement instruments, with support for multi-display setups and a variety of available options for advanced users, such as verification and reporting functionality to evaluate ICC profiles and display devices, creating video 3D LUTs, as well as optional CIECAM02 gamut mapping to take into account varying viewing conditions. Other features include:

Alternatively, if you don't mind trying out development code, browse the SVN[8] repository of the latest development version (or do a full checkout using svn checkout svn://svn.code.sf.net/p/dispcalgui/code/trunk displaycal). But please note that the development code might contain bugs or not run at all, or only on some platform(s). Use at your own risk.
After satisfying all additional requirements for using the source code, you can simply run any of the included .pyw files from a terminal, e.g. python2 DisplayCAL.pyw, or install the software so you can access it via your desktop's application menu with python2 setup.py install. Run python2 setup.py --help to view available options.
A lot of distributions allow easy installation of packages via the graphical desktop, i.e. by double-clicking the package file's icon. Please consult your distribution's documentation if you are unsure how to install packages.
These instruments greatly reduce the amount of work needed to match them to a display because they contain the spectral sensitivities of their filters in hardware, so only a spectrometer reading of the display is needed to create the correction (in contrast to matching other colorimeters to a display, which needs two readings: One with a spectrometer and one with the colorimeter).That means anyone with a particular screen and a spectrometer can create a special Colorimeter Calibration Spectral Set (.ccss) file of that screen for use with those colorimeters, without needing to actually have access to the colorimeter itself.
Here, you can load a preset, or a calibration (.cal) or ICC profile (.icc / .icm) file from a previous run. This will set options to those stored in the file. If the file contains only a subset of settings, the other options will automatically be reset to defaults (except the 3D LUT settings, which won't be reset if the settings file doesn't contain 3D LUT settings, and the verification settings which will never be reset automatically).
LUT[7] based profiles are larger in filesize, more accurate (but may sacrifice smoothness), in some cases less compatible (applications might not be able to use or show bugs/quirks with LUT[7] type profiles, or certain variations of them).When choosing a LUT[7] based profile type, advanced gamut mapping options become available which you can use to create perceptual and/or saturation tables inside the profile in addition to the default colorimetric tables which are always created.L*a*b* or XYZ can be used as PCS[11], with XYZ being recommended especially for wide-gamut displays bacause their primaries might exceed the ICC[5] L*a*b* encoding range (Note: Under Windows, XYZ LUT[7] types are only available in DisplayCAL if using ArgyllCMS >= 1.1.0 because of a requirement for matrix tags in the profile, which are not created by prior ArgyllCMS versions).As it is hard to verify if the LUT[7] of an combined XYZ LUT[7] + matrix profile is actually used, you may choose to create a profile with a swapped matrix, ie. blue-red-green instead of red-green-blue, so it will be obvious if an application uses the (deliberately wrong) matrix instead of the (correct) LUT because the colors will look very wrong (e.g. everything that should be red will be blue, green will be red, blue will be green, yellow will be purple etc).
Choose this option if the profile is only going to be used with inverse device-to-PCS[11] gamut mapping to create a DeviceLink or 3D LUT (DisplayCAL always uses inverse device-to-PCS[11] gamut mapping when creating a DeviceLink/3D LUT). This will reduce the processing time needed to create the PCS[11]-to-device tables. Don't choose this option if you want to install or otherwise use the profile.
To use this option, you have to select a XYZ or L*a*b* LUT profile type (XYZ will be more effective). This option increases the effective resolution of the PCS[11] to device colorimetric color lookup table by using a matrix to limit the XYZ space and fill the whole grid with the values obtained by inverting the device-to-PCS[11] table, as well as optionally applies smoothing. If no CIECAM02 gamut mapping has been enabled for the perceptual intent, a simple but effective perceptual table (which is almost identical to the colorimetric table, but maps the black point to zero) will also be generated.
Note: When enabling one of the CIECAM02 gamut mapping options, and the source profile is a matrix profile, then enabling effective resolution enhancement will also influence the CIECAM02 gamut mapping, making it smoother, more accurate and also generated faster as a side-effect.
Normally, profiles created by DisplayCAL only incorporate the colorimetric rendering intent, which means colors outside the display's gamut will be clipped to the next in-gamut color. LUT-type profiles can also have gamut mapping by implementing perceptual and/or saturation rendering intents (gamut compression/expansion). You can choose if and which of those you want by specifying a source profile and marking the appropriate checkboxes. Note that a input, output, display or device colororspace profile should be specified as source, not a non-device colorspace, device link, abstract or named color profile. You can also choose viewing conditions which describe the intended use of both the source and the display profile that is to be generated. An appropriate source viewing condition is chosen automatically based on the source profile type.
One strategy for getting the best perceptual results with display profiles is as follows: Select a CMYK profile as source for gamut mapping. Then, when converting from another RGB profile to the display profile, use relative colorimetric intent, and if converting from a CMYK profile, use the perceptual intent.Another approach which especially helps limited-gamut displays is to choose one of the larger (gamut-wise) source profiles you usually work with for gamut mapping, and then always use perceptual intent when converting to the display profile.
Please note that not all applications support setting a rendering intent for display profiles and might default to colorimetric (e.g. Photoshop normally uses relative colorimetric with black point compensation, but can use different intents via custom soft proofing settings).
You can set the degree of adaptation to the known device characteristics used by the default full spread OFPS algorithm. A preconditioning profile should be provided if adaptation is set above a low level. By default the adaptation is 10% (low), and should be set to 100% (maximum) if a profile is provided. But, if for instance, the preconditioning profile doesn't represent the device behavior very well, a lower adaption than 100% might be appropriate.
The neutral axis emphasis parameter allows changing the degree to which the patch distribution should emphasise the neutral axis. Since the neutral axis is regarded as the most visually critical area of the color space, it can help maximize the quality of the resulting profile to place more measurement patches in this region. This emphasis is only effective for perceptual patch distributions, and for the default OFPS distribution if the adaptation parameter is set to a high value. It is also most effective when a preconditioning profile is provided, since this is the only way that neutral can be determined. The default value of 50% provides an effect about twice the emphasis of the CIE94 Delta E formula.
If you want to insert a certain amount of patches generated in a spreadsheet application (as RGB coordinates in the range 0.0-100.0 per channel), the easiest way to do this is to save them as CSV file and drag & drop it on the testchart editor window to import it.
As long as you do not enter your own text here, the profile name is auto generated from the chosen calibration and profiling options. The current auto naming mechanism creates quite verbose names which are not necessarily nice to read, but they can help in identifying the profile.Also note that the profile name is not only used for the resulting profile, but for all intermediate files as well (filename extensions are added automatically) and all files are stored in a folder of that name. You can choose where this folder is created by clicking the disk icon next to the field (it defaults to your system's default location for user data). 153554b96e
