First of all, what is reality? There are visual differences in the colors seen by men and women, and there are also differences in color, vision, and visual acuity among human individuals. Will a person with a 300-degree flash be the same as a person with no nearsightedness, farsightedness, or presbyopia? So what is reality? A certain object in the real world has a color of #750000 dark red when viewed with an impartial instrument. So if a mobile phone takes a picture of ##600000 which is too dark, and the screen turns out to be 750000 because the RGB value is raised due to the bright display setting, is this true or false? Finally, do you strive to be real when taking photos...? Do all selfies need to be real? Take a picture of the sky and dig out the gray, so it can't be bluer? The sky is so blue when the weather gets better. Why didn’t I see that blue color when I took this photo? So what does this color mean? Is the sky today very different, BEBEBE or D2E9FF? Can't it be adjusted? It’s so easy to adjust colors these days Not to mention Xiaomi’s magic to change the sky.
