Blurrish lines while taking potrait photos

[chunden13]

As stated in the subject, while taking photo in portrait mode, using rear camera, there will be some blurrish parts on the focused object itself.

For a better understanding, refer to the youtube video below which was uploaded by myself.

Not sure if it is a defect on camera or software issue or it is normal?

anybody faces this issue on their iphone x?

 

[everlast77]

Mine is the same .

It’s the edge recognition algorithm. It will get better over time.

Does it do the same thing when the subject is an actual person? Or even just an object that doesn’t contain a picture on its surface? I’m wondering if the subject in this example is messing with the algorithms that determine appropriate depth of field?

Hi guys, so far I do not think i have serious issue like this when i am taking photo of a REAL person. However, when it comes to food, or any other non human objects, this "blurrish issue" seems to be quite serious, like the one shown in youtube i uploaded

Do you mind sharing the video of it?

Its designed to recognise faces, its not for objects. Sometimes you will get a good shot of an object, other times it will spaz out. Face work perfectly though.

Took this shot on the 8 plus and I think the algorithm really nailed it.

And this one.

And this one.

It really depends on the object and the lighting.

 

[rawlus]

also depends a lot on how good a photographer you are.

This makes me wonder when we will see an iPhone with a rear facing dot projector. That will bring True Depth tech to the rear camera, in addition to 3D object scanning.

Try using an app like Focos which takes the depth information and leta you adjust the blur so more of the subject is in focus. Also has a very cool ability to sho the depth ‘slices’ in your photo

Is this over time as in the more you use it? Or with updates through Apple?

I noticed the issue was pretty awful on my end. If I have to teach my phone what is good in these regards I’m inclined to just never bother with it.

Nope. Not over time. You just need to know where it will work.

So you’re referring to “experience”, yes? You mentioned it will get better over time and I was trying to understand if this is the user improving on their skill or the software improving.

It’s both. The algorithm doesn’t work well in every situation. That’s what Apple will improve with time but as you learn where it actually works, you will be able to take better pictures as well.

Does anyone have trouble with their portrait mode-stage lighting?? I’ve only gotten it to work a few times. I’ll sit forever and try to take pictures (circle needs to turn yellow to work) and it just won’t work .

The first two photos are not a test of that mode. There is no background to blur out.

the background is what the software chose to colour in black. Edge detection is working well there.

I starting to doubt if it is hardware defect until i found that the disay phone in apple shop is having the same issue when i was trying to take potrsit photo.

So can we conclude evrryone will face the same blurry issue depending on situation and lightning ?

Indeed. I face this when the light wasn’t right. Struggled a lot taking this picture.

Even simple autofocus struggles more in low light, because it's based on detecting contrast. The brighter lens and more sensitive sensor help, but you either need something with really clear contrast to focus on or a bit more light. My Olympus OM-D E-M5 can struggle to AF in low light as well, but it's better using a bright f/1.7 or f/2.8 lens than it is with a lens that can't open up the aperture as wide. Even then it will struggle if there isn't enough contrast.

This is why I believe you should (although I don't have an X yet to test this with) get better results with the selfie camera thanks to the dot projector's infrared being able to provide additional information on the depth and shape of the subject.

Ahhhhh. Got it.

Don’t need no stink’n portrait mode (he says with a joking sarcastic evil grin) for that, especially with dark backgrounds.

So far sefie camera works fine just that the rear one doesnt. It has blurry line or cannot even focus when taking potrait mode photo

I don’t think the dot projector is used for anything other than authentication.
