About SuperCal 1.2.2
----------------------------------------

SuperCal is the only visual calibrator capable of properly calibrating LCDs, plasmas, projectors, and good old CRTs. SuperCal creates a ColorSync profile which corrects the response of your display to make it look its best. This means you will see more accurate colors, more detail in shadows and highlights, and cleaner anti-aliased text.


----------------------------------------
New And Special In This Release
----------------------------------------

Version 1.2.2 has been code signed with our developer ID so that it runs under GateKeeper's default setting in OS X 10.8 Mountain Lion. Please see the complete version history at the end of this document for more details.


----------------------------------------
Known Issues In This Release
----------------------------------------

1) SuperCal is not yet multiple-monitor aware, but it can still be used in a multiple-monitor configuration. SuperCal calibrates the main, non-mirrored display (the display containing the menu bar), so to calibrate a different display, use the Arrange tab in the Displays pane of the System Preferences to move the menu bar to another display to make it the main display, then run SuperCal again. You may need to restart after changing the main display because not all systems update their configuration properly after re-arranging displays. When you calibrate, insure that you name your profiles uniquely so that you can double-check that the appropriate profile is being assigned to each display. Note that you can't calibrate with video mirroring turned on. However, you can turn mirroring off, calibrate and generate a profile for each display, then turn mirroring back on.

2) A check has been added to SuperCal at startup to help circumvent an issue caused by the Universal Access "Enhance contrast" setting. In some instances, this contrast setting is not actually turned off by default, and it both causes your display to look mediocre and causes SuperCal to show gray or black patterns instead of color patterns during measurements. If you do not see the warning and still see the gray or black patterns during measurements, simply follow these steps Open the System Preferences, then open the "Universal Access" preference pane. Under the "Seeing" tab, slide the "Enhance contrast" slider all the way to the left to the "Normal" setting to disable this feature. Close the System Preferences and try calibrating again with SuperCal. If the problem persists after doing this, just re-open the Universal Access pref pane and slide the slider to the right, then close the System Preferences. Then, re-open the Universal Access pref pane and slide the slider to "Normal", then close the System Preferences again. This should overwrite the setting two times, fixing the issue.


----------------------------------------
Pricing & Activation
----------------------------------------

SuperCal is shareware which means that you can download it and try it out for free, but profiles created with an unlicensed copy of SuperCal will be "crippled" until a license is purchased and activated. Please see SuperCal's built-in help for more detailed information.

SuperCal costs US $19 for a single user license which can be easily purchased from within SuperCal. Simply choose "License..." from SuperCal's File menu or press the "Unlicensed" button at the bottom of SuperCal's assistant window to open the license window and access the built-in store.


----------------------------------------
System Requirements
----------------------------------------

SuperCal is fully compatible with the following systems that have a 24-bit (millions) or 16-bit (thousands) color display:

Mac OS X 10.8 (Mountain Lion)
Mac OS X 10.7 (Lion)
Mac OS X 10.6 (Snow Leopard)
Mac OS X 10.5 (Leopard)
Mac OS X 10.4 (Tiger)


----------------------------------------
Installation
----------------------------------------

It is recommended that you install SuperCal in the "Applications" folder so that it is accessible to all users, but SuperCal can be installed anywhere on your system, if you prefer. Simply drag and drop the SuperCal icon to the destination folder of your choice.

A copy of this ReadMe file is included inside the application, so you can discard this file and still access its contents from SuperCal's Help menu.


----------------------------------------
Where To Find Help
----------------------------------------

SuperCal has numerous sources of help available to answer your questions:

1. This ReadMe file covers installation details and lists important issues and changes for each release of SuperCal. It is a supplement to SuperCal's detailed built-in help system.

2. Step-by-step instructions at each step of the calibration help guide you along. Use the scroll bar next to the instructions to see all of the instructions.
   
3. A "Why" and a "Caution" button appear on some steps of the calibration to highlight things that you should be aware of and watch out for.
   
4. A full, searchable help system in HTML format is available under SuperCal's "Help" menu, which includes:

	* QuickStart guide
	* Detailed instructions
	* Important fixes
	* Known issues
	* FAQs

Please consult the built-in help to see if your question or issue is addressed there before contacting us with a question. We try to be very responsive to issues and requests, but we do have very limited bandwidth, so this consideration will help us out tremendously.


----------------------------------------
Feedback
----------------------------------------

Don't hesitate to send us an email with anything that you find out of place or that's not working as expected. In addition, if you have any questions on something that's not covered well in the instructions or manual, ask us. We're trying to make the topics as clear as possible, but if they're not, we'll keep trying.

Because SuperCal talks so closely with the video hardware, it's very important for you to report odd behavior with your particular configuration. It's impossible for us to test on every system configuration, and because we only have a couple of machines here to test on, it's not uncommon for things to go unnoticed by us. Even though the application may misbehave on your machine, it behaved properly on our machines before we released it.

Remember, if you don't report the problems, we can't fix them :)

Thanks,
Brock Brandenberg

Version History
----------------------------------------

--------------------
1.2.2 - Jul 25, 2012
--------------------

The application is now code signed with our developer ID so that it runs under GateKeeper's default setting in OS X 10.8 Mountain Lion.

--------------------
1.2.1 - Nov 18, 2011
--------------------

Made a minor fix to keep a dialog from being displayed on 10.4 Tiger stating that 10.5 Leopard or newer is required. This dialog occured during a check for display characteristics and it simply threw a dialog if it used 10.4 methods instead of newer 10.5+ methods.

Fixed a crash that could occur if you had measured thirty to forty points in any single color channel. Note to users: Don't do this. This is far too many points and will typically result in a worse profile than simply measuring a half-dozen to a dozen points. You will get the best results by first working your way down through the shadows to black, calibrating the major points at 50%, 25%, 12.5%, 6.25%, 3.125%, then stepping back up to the highlights 75%, 87.5% and maybe also 93.75%. This is not a definitive guide, but try not to calibrate every single point at which you think you see a difference. Eye fatigue will play tricks on you and you will end up causing ripples in the characterization that cause visual anomalies.

We have re-added the "make and model" tag so that profiles show up in the Display pref pane under the Color tab without needing to uncheck "Show profiles for this display only". If you're curious, see the last step of the user guide under "The Details" for historical information about this "mmod" tag.

Fixed minor bug on 10.7 Lion where the display's depth and frequency values were not being retrieved properly from hardware, and the resulting error code of "1004" was being written into the profile instead. These values are only visible in the "New or Edit" step and they are only for your reference - the values have no significance other than a reminder of the display settings under which the calibration was performed.

--------------------
1.2.0 - Apr 24, 2011
--------------------

SuperCal 1.2 is a major functional update from version 1.1.4.

SuperCal is now a universal binary and runs natively on both Intel and PowerPC machines. SuperCal now requires Mac OS X 10.4 or newer. Please use SuperCal 1.1.4 for Mac OS X 10.3 and older.

Added licensing to SuperCal, which has been shareware-on-the-honor-system since its introduction. Existing registered users that previously purchased through Kagi should use the new license window within SuperCal to request a serial number.

You can now use the arrow keys to adjust the sliders when making measurements. The left/right arrows move the horizontal sliders, and the up/down arrows move the vertical sliders. Holding shift while pressing an arrow moves the slider in greater increments.

The black level measurement screens now have an animated measurement pattern. Simply adjust the brightness slider downward until you can >>>just<<< no longer see the lower moving rectangle, but you can still see the upper moving rectangle. To put this another way, you want the point one step below where you can still see the lower rectangle. The moving upper rectangle is really just a safety measure to indicate when you have lowered the brightness slider too far. If you can no longer see the upper rectangle, you've gone too far, but this will usually only occur if you're in a very bright environment. If your environment is dark, you'll probably always be able to see the upper rectangle. See the built-in help for more information.

The white balance patterns have changed to make the step easier, but you can still select your own custom image if you prefer.

SuperCal now retrieves the display color values (the native tristimulus values) from the default profile for your display, and displays those values in the "Display Colors" step. In the unlikely event that SuperCal cannot retrieve the values form your display, you will see the old selection list to choose the best matching option.

Because SuperCal now uses the actual display colors for your display, you could and should update any old profiles you have. Updating your profiles is very easy to do and does not require you to repeat any of your measurements. The following steps will update the tristimulus data while leaving your previous calibration data intact.

    1. Launch SuperCal.
    2. In Step 3, select the existing profile from the pop-up menu.
    3. Skip over the all the subsequent steps and go to the last possible Step 12.
    4. Save your now updated profile, naming and replacing the existing profile if you like.
       If you have more than one profile, repeat these steps for each of the profiles you have created with SuperCal.

Added a warning at launch for the Universal Access enhance contrast setting bug that affects many users.

Updated the inline help shown in each assistant step, and updated the built-in user manual (help pages).

"Simple" mode has never been implemented, so we just removed the "Expert Mode" checkbox on first step because you're always in expert mode.

-----------------------
1.2.0a51 - Nov 23, 2009
-----------------------

You can now use arrow keys for adjustments in the measurement screens. The left & right arrows move the horizontal slider, and the up & down arrows move the vertical slider. Press shift + arrow to move in larger increments.

New animated black level measurement patterns for easier measurement

SuperCal now extracts and uses the native tristimulus values for your display's colors. For now, you can ignore the choice in the "Display Color" step because SuperCal ignores it. I will change this step in the next build.

Name of existing profile is now displayed in file name field of the save profile step

-------------------
1.1.4 - Aug 8, 2003
-------------------

Added ability to change the image in the white balance step and a persistent preference to save the setting

Fixed bug where tone reproduction curve for "perceptual" target response setting was being set in the profile to the last gamma slider value rather than a proper table of values

Added preference to save the tone reproduction curve for perceptual response as a table or as a single gamma value approximation

Canceling from white balance adjustment would not properly restore previous gamma table, so display did not match settings in subsequent target response step

Added chromaticity values for:
	Samsung SyncMaster 700NF
	Sony GDM-FW900
	Princeton EO90

Added preference to save an "I have paid" reminder

Fixed resource setting that caused long-standing activate/deactivate issue with gamma target slider setting

Updated many resource settings to insure proper font is displayed in window items under 10.3 (Pre-release versions of Panther revealed a number of previously unspecified resource settings. Some issues still remain with item background colors inside of group boxes under the latest pre-release version of Panther. We'll have to wait and see if they're fixed in the final release)

Changed text and button wording in some alert dialog boxes to improve readability

Eliminated frames in help pages due to issues with Apple Help Viewer

Fixed bad line ending characters in ReadMe file that were visible under Mac OS 9 (thanks go to TextEdit under OS X for this one)

Added index file to the help folder to aid searching in Apple Help Viewer

--------------------
1.1.3 - Feb 26, 2003
--------------------

Added chromaticity values for:
	Apple Cinema HD Display 23" LCD
	Apple Cinema Display 20" LCD
	iMac 17" LCD
	PowerBook G4 12"
	iiyama Vision Master Pro 454
	Formac Gallery 2010 LCD

Revised chromaticity values using VonKries chromatic adaptation method instead of Bradford method

Fixed error saving profiles with illegal characters in the file name. Slashes and colons are now filtered in the file name field in Save Profile pane. Colons are a path delimiter under Mac OS 9 and slashes are a path delimeter under Mac OS X (Unix), so they are considered illegal file name characters.

Moved scrollbar from right side to left side of on-screen instructions to make it more obvious

Added a step to the assistant to point out the various sources of help

Added simple instructions above graph in response measurement screen

Fixed a few typos

Updated FAQs and documentation with new and requested information

Significantly edited and reorganized the "Details" section of the manual

Changed format of version strings shown in Finder

--------------------
1.1.2 - Jun 24, 2002
--------------------

Fixed a stupid mistake in the new display color (chromaticity) values for the LCD iMac, PBG4 DVI and eMac. The new tristimulus data was not properly adapted to the D50 illuminant of the profile connection space. As a result, some ColorSync-aware applications such as Photoshop 7 would gripe at launch with a warning about the profile being defective. Read the "Fixes" section of the built-in help to learn how to update your profiles without needing to re-measure your display.

Corrected "types" of some display chromaticities in the internal database so that the type would display properly in the readout for existing profiles in the "New or Edit" profile step. The iMac LCD, PBG4 DVI and eMac were set to "none" instead of LCD and CRT respectively. This is only used for the user's benefit when selecting an existing profile. Updating a profile will fix the "type" stored in it.

Added chromaticity values for the iBook 14"

Increased spacing in Display Colors list to make the list a little more readable

Fixed bug where "Bit Depth" value was not always reported properly in the "New or Edit" profile step. The video mode was being reported on some video cards, not the actual bit depth.

Due to some video card driver bugs, SuperCal now forces 8-bit table entries into the gamma table (removing support for 10-bit DACs). This should eliminate the gray patterns that you may have gotten on the black level measurement. There are very, very few video cards with 10-bit DACs, so I don't anticipate that this will affect anyone at all. If it does, let me know.

Previously, if a gamma table was found in the video card at start-up, no further hardware check was done because it was believed to not be necessary. Some gamma tables could be single channel, though, so we reverted to testing all the time again. However, the flicker when testing has been reduced by changing to a more moderate set of gamma table curves.

Added more detail to the control adjustment section in the manual.

Added ReadMe file to the archive to point out built-in help and important fixes.

--------------------
1.1.1 - Jun 17, 2002
--------------------

Added chromaticity values for the PowerBook G4 DVI 667/800

------------------
1.1 - Jun 16, 2002
------------------

Wrapped up the app as a neat, single icon bundle with built-in help in HTML format

Fixed obscure bug that could cause a crash when the full-screen window closed after finishing a measurement

Added an error trap to catch an un-reproducible, but reported error when leaving the "ColorSync Name" field blank in the Save Profile pane.

Added chromaticity values for the iMac LCD and the eMac CRT

If a gamma table is found in the video card at start-up, a screen flicker no longer occurs when doing a hardware check because it's not really necessary.

When quitting, a screen flicker no longer occurs if a profile was successfully created. Previously, the pre-measurement settings were restored, then the system would set the gamma to the new profile's settings, causing a screen flicker to occur.

Title of "Measure" button on black level and response measurement panes now updates properly to reflect whether or not measurement has already been performed.

Fixed issue that has not revealed itself to date, but that could cause last two bytes of the blue channel of the gamma table that is sent to the card during measurements to be corrupted. If your app has not crashed at startup, you have not been affected.

Information readouts on the "New or Edit" screen now maintain contents properly

Added version numbers to warning dialogs for insufficient versions of CarbonLib, ColorSync, system software, etc.

Added AppleEvent support for "Quit"

Misc internal code factoring and changes to facilitate bringing SuperCal back to Mac OS 8.6 in a future build

Compiled with CodeWarrior 8.0

-------------------
1.1b2 - Dec 8, 2001
-------------------

Fixed error in the tristimulus data in the profile where the first XYZ coordinate of red was being left out, shifting all the colors irregularly. This affected the profile only, not the video card gamma, and only occurred on some display choices (like Apple Studio Display LCDs).

Fixed error in the tristimulus data in the profile where the white point of some CRTs was set to black by mistake. An incorrect data set was being used.

Updated system requirements. ColorSync 3.0 is the lowest common denominator, not CarbonLib, and it requires OS 9.0 or later. We apologize for the mistake.

List in display colors pane properly reflects the user's choice if you go forward or backward a step, then come back. Previously, it would visually revert to sRGB even though the correct choice was being used to set the profile data. However, it still doesn't reflect the setting from an existing profile (coming in a future build).

Add note about gamma slider to the help in the white balance step.

Just a reminder... This is why we call it beta :)

-------------------
1.1b1 - Dec 7, 2001
-------------------

Added gray and color ramps to white balance step

Fixed small update bug that was wasting a few processor cycles

Change wording on target response step

Updated text and images for white balance help

Officially declared beta!

Compiled with CodeWarrior 7.0

--------------------
1.1a11 - Dec 2, 2001
--------------------

Fixed problem parsing the profiles that were changed in build 1.1a10 (sorry... changed writing code, but did not update parsing code to match)

Settings for display type and display controls are now restored from an existing profile

Updated the manual

--------------------
1.1a10 - Dec 1, 2001
--------------------

Fixed problem with value of zero index of gamma table not being zero, which in turn would affect some video card hardware cursors (nVIDIA cards included)

Added the response curve viewer

Fixed update problem with bevel button titles wasting processor cycles in certain steps

Renamed "Finish" buttons in black level and response measurements to "Done" to make them the same as other steps

Fixed reserved field of profile private data structure not being zero

Fixed profile 'vcgt' tag that had extra unused byte at the end

Added new tristimulus values to calibrator and updated several existing ones

--------------------
1.1a9 - Nov 23, 2001
--------------------

"New or Edit" screen behaves as expected

Moved expert mode checkbox to intro pane

Moved display colors pane to next-to-last step

Live preview of white point and target gamma

Revised white point adjustment process

Range of white point adjustment is now based on display type - projector has wider range, while LCDs and CRTs have narrower range for finer adjustment

Improved appearance of response plot

Changed timing of activation/deactivation of controls in response measurement

Renamed buttons in black level and response measurements to to "Next Color" and "Done"

Fixed response graph layout on small displays (800x600 etc.)

Added more display chromaticity choices to display colors pane

Numerous updates to the manual

--------------------
1.1a7 - Oct 29, 2001
