Mac is now a compelling machine in both 2. The upgrade includes a new panel that has an extended color gamut. Producing and Comparing Gamuts. Normal white LED backlights produce a lot of blue light, but not as much red or green light. Late 2. 01. 5 i. Macs are using the not- that- new GB- r LED backlight technology. This creates a much stronger green and red spectral component to match the already strong blue. The larger gamut can reproduce more vivid greens, reds, and their derivatives (cyan, yellow, magenta). These panels can target larger colorspaces, the most common being Adobe RGB in professional displays. In recent memory Apple has never shipped a wide gamut display, I am happy to see that has changed. Hopefully the larger gamut will find its way to all Apple products eventually. Apple decided to go with DCI- P3 instead of Adobe RGB for their wide gamut colorspace. This is an interesting decision, lets try to understand the differences. When we take a 2. D chromaticity diagram of both and compare them we get figure 1 . Apple's target P3 colorspace can cover fewer teals and greens (light shaded area). However, P3 is stronger in yellow- green, yellow, orange, red, and magenta (dark shaded area). If instead we compare P3 to the more standard s. RGB colorspace, the differences are even more significant ( figure 2 ). Figure 1. Adobe RGB in white compared to Apple P3 in black. Figure 2s. RGB in white compared to Apple P3 in black. Real World Comparison — The Teal Lake. I selected a series of test images to analyze the difference in real usage. Using soft proofing in Lightroom against a DCI- P3 target, images were selected which exceed s. RGB but which P3 could reproduce. A pair of files was exported for each image, one in Pro. Photo RGB, and the other converted to s. RGB. Then I visited an Apple Store and annoyed the staff (sorry!). I did bring my calibration tool with software, but they did not let me use it to profile the display. It is very difficult to photograph a screen and have the subtle color differences show up. Most of my illustration here will be generated overlays. Figure 3. First Lake in Valley of Five Lakes, Canada. Image is in Adobe RGB colorspace. First off is this lovely photo of a lake in Canada. The teals in this photo represent a case where Adobe RGB surpasses P3, and both colorspaces are markedly larger than s. RGB. The composite overlay ( figure 4 ) indicates which areas of the image are not reproducible by which colorspaces. Red is not reproducible by s. RGB, blue not reproducible by s. RGB or Apple P3, and green is not reproducible by s. RGB, Apple P3, or Adobe RGB. Each colorspace in turn has better coverage of teal hues, and therefore can reproduce more of the image. Figure 4. The red overlay correlates to s. RGB. At the bottom left is a 3. D plot representing s. RGB in color and Adobe RGB in white. The red shaded area indicates the colorspace coverage s. RGB is missing to display these teal colors. The overlays on the main image and on the 3. D plots relate to roughly the same colors, just a different visual representation. D LAB profiles will be discussed briefly later. Real World Comparison — The Orange Car. Figure 5. E9. 2 BMW M3, modified to be almost the same as the rare M3 GTS. Image is in Apple P3 colorspace. I like orange cars, so does the P3 colorspace. Orange is one of the areas where P3 exceeds both Adobe RGB and s. RGB. In this composite overlay ( figure 6 ) s. RGB cannot reproduce any of the orange paint whereas P3 can get pretty much all of it. Note that if you are viewing this page on an extended gamut display figure 3, 5, and 1. You can download and view these if your browser does not support extended colorspaces. Figure 6. The colors change with each image to keep them visible. I can't use red here because it blends in too much with the orange. The representation is the same. In the 3. D plots it is clear that the gamut required to display the bright, rich orange is only available in the P3 colorspace. On the 2. 7- inch i. Mac in person this photo had a lot of punch. The orange was bright, saturated, and brilliant to look at ( figure 7 ). Figure 7. Doing analysis at the Apple Store. The left side is s. RGB and the right side car is Pro.
