How can a smartphone take pictures of a landscape with everything in focus?

It's worth noting that sensor size plays a huge role in depth of field and behavior of the lens. A smartphone has a tiny camera sensor, often around 25 square mm. This gives the camera a crop factor ...

Do smartphones suffer from degrees of chromatic aberration? If so, how is it possible?

Because the chromatic aberrations happen in the lens, not the sensor - the picture is already distorted by the time it reaches the sensor, so it doesn't matter if there is a Bayer matrix (or any other ...

Why is this smartphone picture better than this dedicated camera picture?

No, your camera sensor is not bigger than your smartphone sensor, they are both about 1/2,5". The difference is that your Canon camera uses ancient sensor technology (more noise), smaller aperture (...

What could be the reason for these block-like artefacts in the blue sky?

I would suggest that it might actually be a sensor fault (or firmware bug). My reason for suspecting this rather than JPEG artefacts or banding is that the surrounding sky has exactly the same ...

Can an old DSLR be upgraded to match modern smartphone image quality

You could get a really fast 50mm f/1.4 [or cheaper 1.8] lens for $£€ 200 second-hand that will make those fabulous blurry background photos that smartphones can now fake quite well, in low light too. ...

What could be the reason for these block-like artefacts in the blue sky?

These look like JPEG compression artifacts, possibly caused by picking a lower-quality setting in the camera settings. On many cameras there's e.g. a Fine JPEG mode and a SuperFine mode, or something ...

How can a smartphone take pictures of a landscape with everything in focus?

If by "landscape" you mean something like this: then the answer is simple: at very large distances, depth of field is extremely large even at large apertures. That is, at any aperture if you focus at ...

What causes these streaked rays from light sources?

In my opinion that "flare" is caused by a dirty lens. I'm guessing you attempted to clean it, by using a wipe, but failed to properly clean it, which is why the flare has directionality. Try using a ...

How many megapixels to get readable pictures of descriptions/prices labels?

It's not really a case of how many megapixels you have - 12mp is plenty just for a product label - it's whether you can get enough light onto the label for the exposure to be short enough that you ...

How can a smartphone take pictures of a landscape with everything in focus?

Aperture is only one factor in depth of field. Others are: sensor size and focal length. Large format camera lenses often have max apertures in f/4-f/5 range, yet they yield very shallow DOF - because ...

How to estimate pixels per degree for an image from a camera phone using EXIF data?

I assume this is a still frame from a video, because 16:9 is a common video ratio. In order to maintain constant frame size, "digital zooming" needs to be reinterpolated. Thus, yes, you need to ...
