Explanation of Camera Quality of Smartphones:
What are the properties of a good
smartphone camera???
A smartphone camera
having more megapixels??? is better right, I think not because alone megapixels
does not define a good smart phone camera, so what is important thing which can
define a good quality smartphone camera?
Sensor is the most
important piece of Hardware when it comes to image quality, there are good
sensors there are bad sensors, there are different types of sensors and there
are large sensor is there a small sensors and everything in between it's hard
to tell a lot about an image sensor just by the name or the numbers but there's
one thing is pretty much Always Rings true which is that when all other things
are held constant a larger sensor an outperform a smaller one, now the cameras
sensors and smartphones are pretty much always tiny, not tiny enough to get rid
of the camera bump and 99% of smartphones these days have got them but
obviously a lot smaller than your normal point shoot, so your smartphone
cameras have to rely on their own tricks to make great picture, I remember
HTC's attempt at an UltraPixel camera back in 2013 a 4 megapixel camera that
claim to be much better at all other things including low-light here's why, a
sensor is a piece of Hardware responsible for turning all the light that hits
it into electrical signals you can imagine it like a grid of pixels, the larger
the sensor obviously the larger the pixels and the more sensitive they can to
be light but all these smartphones sensors are all pretty tiny, so HTC instead
went with way less pixels so that individual pixels are much larger for better
low-light performance now 4 megapixels is still enough to have a decent amount
of detail if you don't zoom in at all but most of the time we see smart phones
at the other end of the spectrum with 12,16,18 megapixel sensors, which gives you a ton of detail
but obviously they will suffer a little more and lowlights.
So in front of the
sensor is all the glass and all the lenses through which light has to pass and hit
the sensor, aside from the quality of the glass the aspect that matters is the aperture
smartphone cameras are all fixed
aperture lenses and generally the bigger the better because the more light you
can let in, so the best smartphone cameras now have F/ 2.0, sometimes even
F/1.9 or F/1.8 apertures which is great for letting like I said a ton of light
in and also getting a little bit of separation between the foreground and
background with a shallow depth of field one thing that is hit-or-miss is
stabilization, so software stabilization or electronic image stabilization is
decent for correcting a little bit of minor hand shake, or if you get a little
bit of a blur it's good at removing that and not having that images but in
video content it can tend to have a little bit of a Jello effect but Hardware
stabilization or OIS is awesome pretty much all the time it's much better for
having longer exposures and while having shaky hands can still produce very
sharp images its better for a low light and it can produce much smoother video ,not
every smartphone uses OIS and not every sensor is even compatible with it but
when it is possible its preferred now aside from that you don't really need to
pay too much attention to the number of a lens elements.
The Flash design I
wouldn't pay too much attention to that either sometimes you can get something
interesting like a ring flash or a dual-led flash or even a Xenon flash but for
the most part I have been using a flash with smartphone pictures.
Every smartphone
camera processes the images that come from that sensor a little bit differently
some do a little bit more sharpening some do less some do a little bit more noise
reduction and some do a little bit less some shift towards warmer colors some
shift towards cooler colors some crank up the situation others keep it pretty
tame some favorite bright exposure some keep it a little bit underexposed but
the one thing about photos is it's all
subjective so you might have a smartphone that takes an objectively more
accurate photo and then another one that takes a little bit less accurate but
also more pleasing to the eye photo.
