Why can’t cameras and screens reproduce colors that are the same as real life? And why are they so different between devices?
In: Technology
LEDs in screens vary in brightness a lot depending on manufacturer variability and even temperature. These variations aren’t consistent across red, blue, and green. So you get color variation.
There are tools to calibrate screens, but it’s an average–a calibrated screen doesn’t guarantee each pixel is correct, just that together they make the right colors and brightnesses. Cheap stuff isn’t even calibrated individually. There’s one factory calibration for every screen of that part number that may or may not work well with your particular screen. Further, things like brightness and contrast are specific to the hardware. Backlights vary too, in color and brightness. You can try to get screens of the same specs to match them, but could still be subtle differences due to different LEDs being used and different calibrations.
The same kind of thing applies to cameras. They have CCD pixels that turn light into electric charge. But their sensitivity also varies. Calibration has similar issues.
