My phone keeps making my skin look different in every room, so I am questioning the undertone notes I made from photographs. In indirect daylight, my complexion looks fairly neutral. Under a ceiling light it looks warmer, while the camera sometimes pushes the whole image toward pink. The pale fabric behind me shifts color as well. I found descriptions of
skin tone analysis but I do not know how much faith to put in an automatic phone image. I would choose even light rather than direct sun. I can turn off beauty filters. I could hold the same white card beside my face and photograph it at roughly the same time on several days. Is it useful to keep camera settings fixed? I could save the camera settings for each attempt. I would also compare the actual fabric in a mirror, because the photo may be recording the room more than my skin. I do not want to overinterpret small color changes. For people who have done this carefully, which lighting conditions gave consistent observations, and when did you decide a photo was misleading? I can try the setup more than once to check consistency. A practical checklist would help me separate the camera settings from the colors I am trying to judge.
