    Is 48MP camera better than 12MP camera?
    Why Iphone 11 still using 12MP?
    But many china brand phones using 48/64/108 MP camera.
    is it really higher MP will produce better shot?

    I think the main thing in the "picture" is the lens...
    Phones can't match the lens in a DSLR camera so I expect a phone with a large claim on Megas won't match the quality of the DSLR camera... also I think the phone is limited in sensor size and Megas are derived from multiple lens trickery.
    Mind you the quality of photo from phones surprises me...mine has upto 60x zoom and even without a tripod (which one needs for zoom) it produces a respectable image...way way better than I expected.
    And I love the slow motion feature...had a swallow in the van and the capture was incredible...and just a phone.

    A few folk are using their phone for astro photography with most pleasing results.

    At a certain point it probably depends on how much you intend to magnify the image and how good your eyes are.

    just a simple question, is higher MP the better the picture quality?

    Yes but at a certain point you may not be able to tell the difference. If you aren't magnifying your pictures excessively you may not be able to tell the difference.

    You can tell the difference between a 3 MP image and a 12 MP image. I don't know how much you can tell the difference between a 48MP image and a 12 MP image.

    Not necessarily.
    If everything else about the camera is the same, then yes, technically it should give greater quality to the picture in that it allows for greater detail.
    But the way the camera handles and processes the image is probably more important.
    A good 12MP camera will be better than a poor 48MP camera, if it can handle colours and brightness/darkness better, and provides more options with the lens, for example, and all the other bits and bobs that go in to making the image look good (beyond the actual composition of the image).

    What is the f/1.8, f/2.0, f/2.4 etc spec?
    Seems that f/(smaller number is better)

    The f/number refers to the lens aperture, or how much light it can let in.
    The lower the number the better, as this means a wider aperture, letting in more light, which is great for low-light environments.
    Lower numbers also mean you can have faster shutter speeds, as enough light can get quickly.
    Therefore it is good for action shots, reduces motion blur etc.

    It’s not always true that lower f number is better, as there are other things to consider, such as the lens itself.
    But in the absence of any other data, it gives an indication of performance in low light, and to shutter speed.
    And with mobile cameras, low-light performance is often important to the user.

    The best pictures are taken when you don't have a loose nut behind the camera.

    The smaller the number, the larger the aperture, which lets more light in. Thus you can use a higher shutter speed for the same light levels and avoid blur due to motion and camera shake.
    The trade off is that a larger aperture also lowers the depth of field. Depth of field determines how much leeway you have have in terms of focus.

    So for example, this would be what you might get with a small f-stop:

    And this is what you would get with a larger f-stop

    In both cases the focus is on the point of the cylinder in the middle of the frame. In the upper one, the focus gets blurry for nearer and further parts of the cylinder. But in the lower one the entire length is is pretty sharp focus.

    So, whether a larger or smaller f-stop is "better" depends on needs of the photo being taken.

    I used to have a medium format camera, Mamiya 645 1000s. I could blow up pictures to 4x5 feet without losing resolution. I don't know how close digitals have come to that these days.

    while you are not wrong
    i think saint is in the middle of new consumer product market wars
    cell phone companys do not want to put in processors that drive a 48mp camera

    it will make the cell phone crash then all the customers will be asking why the cel phone is slower than the $1,500.00 one they bought last year.

    those market influencers who drive new sales are youtube blogger social media savy tech aware people who know how to utilise advancements to get better quality content for their fans.
    however
    that doesnt sell profit margins for the ISP's because they dont want to give band width.
    it only flys well on downloadable platforms

    lol at everyone talking about 5g
    it sounds nice but its like using a mining dump truck to drive to the shop to buy a loaf of bread.

    remember these are Chinese circuit boards
    made for 50 cents sold for $500.00(by western tax dodging companys)
    what is their true board rate(board-rate speed width & capacity) ?

    How about the Sony's IMX586 sensor?
    Why most phones are using sony sensor?

    where will you store the massive amounts of picture data ?

    lol

    sony are good, but they dont control the cell phone producers choice of storage and processor speed and board rate

    My stacked astro images when using a 3x drizzle are 1.6 gig each before they get to the image processing software and there are usually 7 individual photos merged into one that is reduced to 80 meg and then to 20 and to post here down to less than a meg.

    Do you not have Google?

    It determines what type of "out of focus" effect you get.
    For example, here is a image without bokeh effect.
    The blurry spots are distant cubes like the one in the foreground.

    The same image with a bokeh effect applied:

    Now the out of focus cubes have a more "triangular" look to them. It is basically an artistic effect.

    Unless you have an infinite focal length, only those things that are focussed on will be crisp and sharp in the image.
    Everything else will be out of focus / blurred.
    Bokeh is the way that the lens renders those out of focus parts.
    Look it up on wiki if you want a greater explanation.

    Can AI camera focus near and far distance objects, combine both into a clear picture?
