Review and tutorial: i1Display Pro and i1Profiler

The X-Rite i1Display Pro is a monitor calibration device, also known as a colorimeter, that allows you to colour-calibrate your display and create an ICC profile for it. Together with X-Rite’s new i1Profiler it allows you to calibrate not only a computer monitor, but also a projector.

The i1Display Pro is the new display calibration instrument X-Rite releases since the i1Display II. The new device is more accurate and combined with the new software, it gives users more control over their display. It can measure and calibrate all current monitor types as well as projectors.

The next videocast runs you through the basics. It’s also the first part of a multi-part tutorial that will take you through all the features the i1Profiler interface has to offer, including an explanation of most options. This first videocast is free; the next parts of the complete tutorial will require a subscription.

Part 2: Setting display and profile options

This part of the tutorial explains which settings you should select and why.

Let’s first see to it that you have a good understanding what chromatic adaptation is about and why one method is better than the other.

 

In colour science, chromatic adaptation is the estimation of the representation of an object under a different light source than the one in which it was recorded. A common application is to find a chromatic adaptation transform (CAT) that will make the recording of a neutral object appear neutral, while keeping other colours also looking realistic.

Comparisons of images balanced by diagonal transforms in a number of different RGB spaces have identified several such spaces that work better than others, and better than camera or monitor spaces, for chromatic adaptation, as measured by several colour appearance models; the systems that performed statistically as well as the best on the majority of the image test sets used were the “Sharp”, “Bradford”, “CMCCAT”, and “ROMM” spaces.

Of those, CMCCAT 2000 and CIECAT 2 are better than the others for photography and videography.

Another term used in many colour monitor calibration programs is “Tone Curve” or “Tone Reproduction”. This is the mapping of scene luminance and colour to print reflectance or display luminance, with the aim of subjectively “properly” reproducing brightness and brightness differences.

The tutorial is a videocast which opens in its own window. Please set the window width to 1280 pixels to view the entire video.
