Display Gamma 1.8 vs 2.2
There is so much wrong information on the internet on this subject some of which come from otherwise “reliable” sources.
When you are calibrating the color of your display picking the gamma is NOT a personal preference, there is a correct and a wrong setting for your display. Most displays that come with Windows computers are designed to produce colors correctly with a gamma set to 2.2. Apple computers for many years were designed to produce colors correctly with a gamma set to 1.8. In the mid 2000s Apple switched to making gamma 2.2 displays.
Many people think it is a personal preference what they set their display gamma to but you need to find out what your display was designed for otherwise your tones will be too light or too dark. A gamma 1.8 display and a gamma 2.2 display when correctly set up should be indistinguishable from each other in color tonality. There is nothing better about one over the other, they are just two different standards. All Apple displays from the last 10 years are 2.2 displays.
Also, your display gamma has nothing to do with the gamma of an image you are working on. Macs at least have always been able to show the correct colors and tones of a 2.2 photograph on a 1.8 display and vice versa.
There are way too many photography tutorial sites with completely wrong information about the topic of gamma. Luckily the default across the board is now 2.2 so it’s mostly not an issue any more but it’s amazing how many people will form an opinion on a topic with having no facts and information to base it on.
