Does True Tone turn off automatically when in the photos app or watching videos?

    As my title says, does anyone know about this? What about for HDR content? I’ve tried checking by turning it off and on while in the photos app, but I can’t quite tell if it’s using it or not. Maybe my eyes adjust too fast to it during the couple steps it takes to go back and forth, even when using the control center to toggle it.
    If it doesn’t disable TT for photos/videos, what do you all think, better to turn it off manually for those things?

    It definitely doesn't shut off for video. I'm not really a fan of true tone so far but I'm keeping it on to see if I can get used to it.

    Back when True Tone debuted on the 9.7" iPad Pro, True Tone did automatically disable when launching the Photos app.

    However trying this on my X, True Tone definitely does not automatically disable.

    I'm not sure if this is an iOS 11 change.

    I find True Tone to be much more accurate in color tones so am happy to keep it on at all times, including photos and videos.

    I wonder if it is actually more accurate, or feels more natural to our eyes?

    It definitely feels more accurate to me. Also more comfortable to use.

    I certainly agree with the more comfortable to use - I am loving True Tone so far in that regard!

    It’s definitely off when you are in the photos app. Not too sure if it turns off for anything else.

    Just like with TV’s where you generally want to set it to the warm setting to have a more accurate representation of the shows/movies watched. On an iPhone you’ll want True Tone enabled for the same reasons. Content is usually edited to be viewed on the warmer side and not on a blue screen.

    No, if True Tone is on, it will stay on when in photos. Compare with a photo with lots of white.

    I have been wondering about this on my iPad. I don’t think it does, so whenever I watch Netflix I turn it off.

    Comparing with a white picture, it’s seems you are correct. It does seem as though the effect is lessened but it’s not off. It might just be the True Tone restibg to wherever I am idk.

    True Tone makes the screen more comfortable, but not more accurate. It literally applies a warm tint to the screen - that makes the colors deviate from the factory calibration of the screen.

    I don’t think that’s true. Because when you calibrate your tv, you calibrate it to the lighting you’re generally going to be viewing that tv it at. And that’s exactly what True Tone does. It shifts based off ambient light.

    No. These panels aren't reflective - for best accuracy, ambient light isn't normally taken into account. At least not to the degree at which it is right now with True Tone.

    Over the years, I have hated warm displays. My iPhone 8 Plus has a perfect tint to it, but I have grown so accustomed to True Tone, that it bothers my eyes when I turn it off. I find it ironic that the time I finally get a perfect color tint, I don't take use it.

    Oddly enough, True Tone still shuts off in the photos app just as it always has on my 9.7” iPad Pro running 11.2 beta 2. It’s defintely not shutting off in the photos app on my X though.

    True Tone makes whites a more accurate white based off the ambient light you’re in. If you’re whites are right then so are your colours.

    If your whites are on the blue side it shifts all your colours off as well. Same goes for if your whites are too orange.

    iPhone X has a much better ambient light sensor. I believe 10bit while other versions of True Tone only have something like 4-6bit ambient light sensor. It probably stays on for the 10 because it’s just more accurate than previous (even including what’s in the 8/8+) versions of True Tone.

    Sigh... that's not how calibration works at all. True white is a certain kelvin value - ambient light color doesn't change the accuracy to the reference kelvin. This is the last reply I have to give on this matter - you can google this on your own time if you need any more information.

    So perhaps it’s fine on the X to just keep
    True Tone on and not worrying about whether or not it turns off in photos app or when viewing videos. That would be nice if that’s the case!

    Except the colours coming off the screen can be influenced by the ambient light you’re in. That’s a fact. Ambient light will change the perceived colours.

    This is where True Tone comes in and adjusts, allowing those colours to be properly perceived by the eye/brain again.

    Interesting possible explanation. It would be nice if Apple gave us the option to turn it off in photo and video apps though. I’d rather colors not be adjusted for ambient light when I look at photos. Of course, I’m finding True Tone to be a bit too aggressive in general on the X so I’m considering turning the feature off.
