    Ever since we released Portrait Mode, it has been a real fan-favorite. We define a high-quality feature as a feature that meaningfully improves a user’s experience with our devices over a long period of time. That means developing a Portrait Mode that lets you take genuinely better photos. Portraits can be honest and intimate, charming and whimsical, and dramatic and awe-inspiring.

    Difference in Power
    Professional cameras depend on optical processes that require a lot of physical space, such as the use of a long lens, to compensate for a lack of size we use a dual camera setup and computational imagining techniques. The OnePlus 5T’s hardware and software package gives our phone several tools to produce DSLR-like results. Not only are we able to process images more quickly, the hardware also enables us to run more complex software algorithms. As the capabilities of computational photography increase, the limitations preventing mobile cameras from taking professional-level photos decrease.

    Two Lenses, One Focal Length
    Commonly, dual camera setups crop images when shooting in portrait mode. Because most dual camera setups use lenses of different focal lengths, the visible extent of any given scene changes when you shift from one lens to the next. The longer the focal length of a lens, the smaller the visible extent of a scene is. In portrait mode, both lenses are used to create a depth map. This means the size of the area that can be captured is determined by the lens with the longest focal length. In practice, this means that switching to Portrait Mode from the default shooting mode forces the camera to zoom in on the subject. As a result, you have to awkwardly adjust the distance between the camera and the subject to capture the same portrait. As both lenses of the OnePlus 5T Dual Camera feature the same focal length, portraits are no longer cropped, and a wider scene is captured.

    True Clarity
    Behind any great portrait is a series of software algorithms designed to improve clarity. To fully understand how all of these algorithms work, we have to trace a portrait’s journey from your lens to your hard-drive.

    Step 1: Analyzing frames
    When you capture a portrait, both lenses of the OnePlus 5T analyze the same scene using a custom algorithm. By comparing frames of the same photograph, the OnePlus 5T can create a pleasant portrait. In the first step, the two sensors use one another’s captures to create a depth map, which tells the OnePlus 5T where to apply a depth-of-field effect and helps determine the intensity of the effect.

    Step 2: De-noise
    The OnePlus 5T uses a de-noise algorithm to detect and reduce noise in portraits taken in low-light conditions. Noise is essentially random, which means that no two instances of the same scene will ever have the same amount and variation of noise. So when the OnePlus 5T analyzes multiple instances of a scene, it can reduce noise by filtering out inconsistencies. The result is a clearer portrait with little to no noise to ruin your shot.

    Step 3: Depth Map
    Using the depth map and de-noise, we can create a clear portrait with an authentic depth-of-field effect. To further improve the clarity of a portrait, the OnePlus 5T Dual Camera increases the importance of faces in portrait shots. As a result, the face – the most important part of any portrait - is more distinct from the rest of the scene resulting in a more appealing final shot.

    Step 4: What a Beauty
    At OnePlus, we are all about giving our users options. So, if you’re looking for a realistic reflection of your subject you can turn off beauty mode. Otherwise, simply tap the button in the UI to beautify your next portrait. Our goal with beauty mode was to fade out blemishes and create a more even portrait. It obscures the more uneven parts of a portrait, and adjusts brightness to improve the final shot.

    What this all adds up to is our most powerful portrait mode yet, with improvements to accuracy, clarity and dynamic range. Portrait Mode remains one of our most popular camera features, and we are committed to optimizing Portrait Mode on the OnePlus 5T through future software updates.

    Portraits are all about intimacy and honesty. With Portrait Mode we want to give you the tools to take captivating portraits wherever you go. We’re curious to find out where you will take your portraits. So, share your best portraits with us on Instagram and Shot on OnePlus, be sure to share your thoughts and comments on our Portrait Mode.

    I honestly still believe it's a bit gimmicky. If the scene is a bit more complex, it misses horribly.

    A clear example:

    Louis,

    Why don't you guys use OIS over EIS? OIS is better at reducing noise then EIS. Are you guys thinking of implementing OIS in future OnePlus devices?

    It works well enough, but I think the next step it’s to try and make it differentiate even better the soft edges in the pictures - like the hair.

    Speaking of de-noising. Any chance you can address all the complaints about the watercolor / oil-painting effect caused by post-processing?

    OIS -> Photo (mainly)
    EIS -> Video only

    EIS is not used in photos, meaning you have no stabilization system for photography, only video.

    Ah thanks for th correction, so no image stabilization on the 5/5T!! That's why there is noise. Implementation of the OIS is definitely a necessity.

    Albeit that's taken via the oneplus 5 and not the 5t(as claimed by him), what you say still stands true. Both the phones (especially considering 5t has a different secondary sensor altogether) still miss out terribly on the portrait mode and sometimes low light/day light photos (like oil painting effect). Hopefully the update early this month that Carl spoke of would solve this (and for 5 too). Fingers crossed :oops:

    There are ways to go around that like having a greater aperture (lower f/ number) so more light gets to the sensor or using bigger pixels (so each individual pixel gets more photons).

    But the perfect scenario is having those three things combined (like the Pixel 2): A big aperture (f/1.8), big pixels (1.4 μm) and OIS.

    OP5 and OP5T have a better aperture (f/1.7) but smaller pixels (1.12μm) and no OIS.

    Taking in consideration that the 2x or 1.6x digital zoom on the 5T achieves good detailed images, why not give us the option to also use portrait while zoomed in?

    With the current "wide angle" portrait, a zoomed portrait option, and with the ability to change the blur, it would be the most versatile option on the market to date.

    Okay so prioritise a product launched just over 3 weeks ago but completely shove aside another launched 4 months ago for which there has been MANY complaints on the same subject you now speak of? Hmmmm. :/

    You're right about those three things being combined. You also forgot to add better camera software algorithms :D

    Because Samsung keeps talking about the S7 nowadays. /s

    Of course they will focus on their latest device. People do like to complain about everything.

    Last thing Oneplus needs to boast, Camera !
    You have great phones. May be great camera hardware too. But poor processing software algos .
    Buy me a peg and i will talk otherwise.

    You can just crop the picture, which is what digital zoom does anyway.

    Love the username BTW :D

    OnePlus 5 slow motion camera needs huge improvement. it looks like we have zoomed in for the shoot.

    There is sensor quality also (pixels size are part of it) that matters
