True Tone

[imagineadam]

So true tone is basically automatic night shift during the day right? Basically all true tone does is adjust the color temperature based on your surroundings? Am I correct? So really all iPhones that can do night shift really already have this but we have to adjust manually? Am I right? Or does true tone do something else besides change the color temperature of the display?

I always turn on night shift once the sun sets on my iPhone 7 and I'm inside around our yellow lighting. If I'm at work the light is blue light so I keep night shift off cause it would look way too yellow. I guess my point I'm getting at is that it's a cool thing but it's really not that cool because all us people who don't have true tone actually do because we just need to turn on night shift and adjust the slider to get the same effect... or am I missing something about true tone?

Here's a nice explanation.

I turned True Tone off on my 10.5. They can write books about the supposedly mindblowing awesomeness of display tech that dynamically adapts the white balance to the ambient light, but if all the sensors do at the end of the day is arrive at the same conclusion that the image needs to be soaked in yellow, then I’ll pass, thanks. Sometimes “natural” doesn’t mean better. 30 fps produces a more realistic and fluid image than 24 fps, but the brain still screams “soap opera effect!”. I’ll rather have a slight blue tint than one that makes a new bright display look like a 20 year old newspaper.

All it really is is an automatic full time night shift. When you are inside it makes it warmer. When you are outside it's more blue.

 

[jpn]

it adjusts both intensity and white point automatically.
the user can duplicate this by controlling both Brightness and White Point.

i agree very much with what a poster said a few posts above:
i haven't ever used Night Shift since i do not find it enjoyable viewing anything that looks like the equivalent of a 20 year old newspaper.

i haven't played enough with True Tone to understand if i will find it useful or not.

on the other hand, damage to the eyes by having too much blue light exposure for frequently 16 or 18 hours per day is probably harming eyes.

I trust science regarding this thing with blue light screwing with your sleep patterns, so I've enabled Night Shift on all my devices; it kicks in at 10 PM. However, I've set the slider to 25% rather than the default 50%.

I mean, the default 'medium' setting is just nuts. It adds a massive amber tint to everything, and combined with the default auto brightness setting in a dark room, it makes it virtually impossible to read anything on the screen – you have to turn up the brightness or disable Night Shift. Unless the idea is to make the user just give up, put down the device and go to sleep, I don't really see the point of rendering it unusable.

The maximum Night Shift setting... I don't even know what that's for. Maybe to simulate what it's like to use an iPad inside a volcano? "Wanna know what an eternity in hell feels like? Grab your iPad, lock yourself in a sauna, set the Nyan Cat song on repeat, crank up Night Shift to the max and scroll through a never ending list of Trump tweets!"

It uses a sensor to determine your ambient light and adjusts white balance on the screen accordingly, to make colours more accurate.

It’s not just night shift.
Night shift deliberately makes colours warmer and less blue than they should be

my eyes always adapt to nightshift in a few minutes or less. doubt it would be different with true tone

 

[drygioni]

I couldn't stand it. Tried it for an hour before turning it off.

That's technically true, although it always seems to arrive at the same conclusion: What your display needs is more yellow tint. True Tone is a bit like the Sirius Cybernetics' Nutri-Matic Drink Synthesizer in The Hitch Hiker's Guide to the Galaxy:

"The Nutri-Matic Drink Synthesizer claimed to produce the widest possible range of drinks personally matched to the tastes and metabolism of whoever cared to use it. When put to the test, however, it invariably produced a plastic cup filled with a liquid which was almost, but not quite, entirely unlike tea."

Who knows – maybe True Tone actually produces a different result outdoors in direct sunlight or inside a tanning bed, and maybe this will become more useful on iPhones since they see a lot of different environments, but when it comes to iPads I think that the vast majority of them are used in homes, with fairly uniform and predictable lighting conditions, which means you're gonna get a light version of Night Shift in 99 cases out of 100.

So is it worth having Night Shift on anymore if True Tone does practically the same thing all day?

Night Shift turns everything sunset orange.

True Tone adapts the color temperature to its surroundings. If you're an avid collector of blue neon tubes and your home looks like Mr Freeze lives there, True Tone will likely shift the color temperature toward blue. but if you're a regular human in an off-white room lit with IKEA bulbs, True Tone will make everything yellow-ish.

So they do different things even if it doesn't seem like it.

Thanks. Think i'll probably keep them both on.

Compared to regular displays, real life does have more yellow tint.

Two different things

Night shift makes your screen excessively warm / orange to help you sleep better. It deliberately makes the display “wrong”

True tone doesn’t do that.
The idea behind true tone is to make the display match ambient light.

I.e. if you have a white piece of paper on your desk and your room is lit with 6700k lighting then the display will show white (e.g. a photo of said paper) at 6700k colour temperature as well.

Have you even experienced Tru-Tone to make that assumption. Tru-Tone simply uses sensors to correct the white point on the dislay for more of a natural looking
Of a natural appeal with images. Night Shift intentionally yellows the dislay for an easier transition on the eyes away from the blue light spectrum.

 

[Technarchy]

I would not enable it for 5 minutes and turn it off.

Actually leave it on and understand how it works before making a decision.

Use it at home, work, in sunlight and under clouds. You’ll understand it better and know if it appeals to your eyes better then.

It’s not less aggressive night shift. Not even close.

 

[BeeGood]

I couldn't stand it. Tried it for an hour before turning it off.

Like others have said, you may want to give it a try for a day or two in order to see how it looks in many different lighting conditions, and especially both indoors and outside.

TrueTone is a complete FAIL - a stupid gimmick that will cause more trouble than its worth.

Try to edit colors in photos with True Tone on ... hahaa.

 

[throAU]

True tone isn’t fail

Every other display you’ve used previously is probably wrong and excessively blue.

What you’re used to is most likely wrong. Not true tone.

Oh yeah, total fail, all the rest of us do it edit photos on our iPhones all day and require correct colors! Nevermind that it makes the screen much more comfortable to read, since we never text, browse safari, use apps, or anything else.

 

[ProMod]

Mine and my wife's 8+'s handle True Tone totally differently. The two displays are very similar with TrueTone off, but with it on, mine always goes much more warm than hers does. I guess it's a difference in the sensors?

 

[204353]

30 fps produces a more realistic and fluid image than 24 fps, but the brain still screams “soap opera effect!”

I presume you mean 60 fps? The difference between 24 and 30 is tiny. The 'soap opera effect' usually refers to the horrible motion smoothing that a lot of TVs add by default. This involves taking the 24 or 30 fps source and interpolating it to 60 fps to match the 60Hz refresh rate of the display.

Also, I don't see how that has anything to do with True Tone. I've used True Tone on the iPad Pro and it's great. Makes the display much more comfortable to look at, mimicking the appearance of a magazine or piece of paper.

That said, there's a reason it's optional. Everyone has their own opinion, which is why the device set-up asks whether or not you'd like to use it.

No, I mean 24 vs 30. The SOE moniker predates our fancy 120/240Hz hi-refresh rate LED TVs with motion interpolation, it wasn't coined yesterday. It refers to the cheesy daytime soap look caused by shooting straight to video at 60i, as opposed to fancier TV shows that were shot on 16mm at 24 fps. Both were converted to 30 fps (PAL) / 29.997 (NTSC), but the difference was still very apparent on a CRT TV.

What's different now is that modern TVs with motion interpolation exacerbate the problem by SOE-ifying 24 fps material, something an old analog CRT set just couldn't do. 30 fps didn't kill the 24 fps film look; digital motion interpolation does.

Also, I don't see how that has anything to do with True Tone.

Both are examples of our brains clinging to what we're conditioned to. On paper, there's nothing about 24 fps that makes it "better" than 30 or 60, quite the contrary. It sucks for panning across landscapes, etc. And yet, people need their 24 fps for that film look magic. Peter Jackson's 48 fps experiment wasn't well received, and everyone's googling instructions for how do get rid of the SOE on their new TV.

On paper, automatic white point adjustment certainly seems "better" than an unnatural bluish tint. And yet, a lot of people can't stand True Tone, myself included. It sucks for watching movies and shows, as it adds an icky sepia tint to everything. Yellow doesn't really give a lot of positive associations. It's the color of urine, coffee and nicotine stains, of yellowed wallpaper, of faded photographs, questionable dental hygiene and hepatitis. It makes my 5 day old iPad Pro look like the dying display on the 10 year old iMac 24" I keep in a dark corner to tinker with Windows on. So thanks, but no thanks.

Have you ever gone to the paint section of a hardware store? When looking at the color swatches they have, have you noticed how they have those little
Light boxes, each with a different light temperature. When you stick the paint swatch under the light it literally changes the color perceived by your eyes, so the paint will look different under different lights.

True tone works by shifting the white point on the display to make sure no matter what lighting you’re in, the colors on your phone will always look the same.

So how does True tone work with Nightshift turned on?
